ALVESTAD COMPHATCH

Alvestad Marin CompHatch A simple system containing 8 levels that provide capacity for 360,000 roe and fry

Alvestad Marin CompHatch Turnkey Hatchery System Handles 360 000 roe and fry The CompHatch hatchery system combines an efficient design with complete control of the hatching process. Using an eight-floor cabinet with two sections on each floor, the system handles 360,000 roe grains and fry of Atlantic Salmon.

Produce over 1 mill. fry on 4m2 Traditional hatchery systems need lots of space and lots of hard work to function. To produce 1 million fry, a traditional system needs an area of up to 120 m2. When using CompHatch systems, you will produce more than 1 million fry on just 4 m2.

Optimum water quality for roe grains and fry The CompHatch system optimizes the water quality by continuously controlling the water flow rate. In order to make fry lie stable and avoid skin damage the hatchery sections are positioned upstream. CompHatch is delivered complete with EasyHatch hatching substrates. Option: Light-proof cover Design: Aluminium / plastic Size: Height 1750 mm Length 1600 mm Depth 800 mm Contact Sterner Today about the CompHatch; Tel: 01463 250275 Email: info@sterner.co.uk

Hatching Equipment Astro-Turf 

The new type of Astro-Turf is more rigid and has larger holes for



A perforated plastic sheet is put upon the hatching substrate, and eggs are dispersed all over the plastic sheet. During hatching the yolk sack fry will swim through the perforations in the plastic sheet and they get protection in the hatching substrate. This gives better utilisation of the yolk sack which subsequently will lead to higher starting weight. Brown type of Astro-Turf is now standard: The new type is more rigid and it has larger holes for flow through of water compared to the traditional green type (no longer available).

Bio-Bunn 

Astro-Turf is normally fixed to the bottom grate by using poison free silicon or fastened using thread. It is crucial not to seal too many holes due to the flow through of water.

The Bio-Bunn hatching substrate is delivered in sets of two mats, pre-cut to fit into our hatching boxes (40x40cm).  The eggs are dispersed evenly upon the upper plastic sheet. At hatching the yolk sack fry will swim through the perforations in the plastic sheet and look for protection in the hatching substrate underneath. The substrate gives the fry the necessary support to prevent yolk sack deformation. Better utilisation of the yolk gives better starting weight.  The substrate is also suitable as fry shelter in start feeding tanks. It is a well known problem when you transport fry from the hatching box to the start feeding tank that the fry shows a tendency to tighten the outlet bottom sieve. By placing one of the BioBunns with the spikes towards the bottom of the thank, all the fry will take shelter underneath and the problem is solved. The use of a hatching substrate has been proven to give the following advantages:  Less stress and increased growth  Prevents yolk sack deformation  Higher starting weight (20-30 %) gives easier start feeding, better survival and more vigorous smolt.

Fish Counting

AQUASCAN CSE SE-

AquaScan Counters Fast, reliable accurate counting

Apollo Grader and AquaScan Fish Counters

AquaScan Counters Accurate Counting AquaScan is based on a patented counting principle which gives both high capacity and accuracy. The fish flow freely through a pipe and pass an advanced camera/measuring system which will register the size and speed of the passing fish. The resulting data is then transmitted to a control unit which may handle as many as 4 channels (e.g. during grading) simultaneously. AquaScan KD control unit The AquaScan Control Unit will always show the total number of fish passing through the registration unit(s). The powderpainted aluminium case is sturdy, splash proof and user friendly. It has 100-240 VAC input power, fluorescent buttons and backlit display. The input channels can power and control up to 4 CSE/ CSW or 2 CSF registration units at the same time. It also has connectors for auxillary equipment like PC, external siren and PLC/pump control. The adjustable carrying handle can also lift the front of the Control Unit (to approx. 10º, 30º and 45º) for easy operation and a better view.

AquaScan CSE The CSE-units are used for ―dry ―- counting (pipe 0-1/5 full of water through the unit). Available in four models, the two smallest models are introduced here. AquaScan CSE1600: Dimensions: 315x410x235 mm Weight: 14 kg Inner diameter: 150 mm Flange connection: DN150 Capacity, ca: 20000 fish (100g) / hour Fish size: 1-1000 g AquaScan CSE2500: Dimensions: 410x610x265 mm Weight: 23 kg Inner diameter: 240 mm Flange connection: DN250 Capacity, ca: 20000 fisk (1kg) / hour Fish size: 3-7000 g

AquaScan CSW  



Fish counter suitable for fish down to 0.2g. Compared to the traditional CSE counters, the CSW counter has higher resolution and therefore it will ―see‖ more. In addition, the CSW counter has a flat and wide counting channel (28 cm) so that fish are spread out on a larger surface. Due to these aspects, the counter is also extremely suitable for fish smaller than 1g. The AquaScan CSW counter must be connected to the KD control unit and possibly PC connection.

Fish Pumps Blue Comfort P16 fish Pump 

 



Easy to operate. The flexible hoses may be placed on top of the machine. Just connect the fish pump to the power supply and the pump is fully operational. The strong and adjustable supporting leg makes it easy to handle. A large inlet funnel and custom built connections enable gentle pumping. The funnel is fitted with rubber protection to ensure that the fish are unharmed during suction. The fish are separated from the water by a large bar separator before weighing and sorting. The water is led back into the pond. The pump itself is a simple construction, which leads to reliable operation and few repairs. The containers may be tilted to provide constant pumping and they can operate without the use of electronics. This prevents operational failures caused by frost, humidity and the ingress of water into vulnerable parts.

Blue Comfort P16: Capacity: 0-16 t/hr Fish size: 0-5000 g Max suction height: 5 m Outlet (fish): 0-230 mm Outlet (return water): 0-200 mm Bar distance: 8 mm Dimensions: 360x155x230 mm Weight: 650 kg

Blue Comfort W6 fish scale  

 

The fish scale machine may be fitted with a funnel for manual operation. The fish are fed into the scale and the revolving cylinder, which is emptied into the basket at every complete turn. Each quantity of fish is weighed, each weight is registered and displayed. The counting mechanism can total the individual quantities. The accumulated quantities of fish are easily read off the weight display. After weighing, the fish are gently returned to the production pond or tube system for delivery. The fish scale can be fed manually or operated together with the fish pump.

Vaccination & Anaesthetic Equipment Lumic vaccination machines 



Lumic LV-6 vaccination machine

   

 New type of control system

New type of vaccination syringe



The new Lumic vaccination machines are strongly improved compared to the old standard machines. The machines are more user friendly due to separate lifting mechanism for each vaccination trough. New type of vaccination syringes with preset doses. The standard versions are 0.05 ml, 0.1 ml or 0.2 ml doses. Syringes with other doses also available. The new type of syringe is very accurate and long lasting. The control system alerts you if there is a vaccine clogging. Possible PC connection. An open and well arranged system where the operators always have full control of the various functions of the machine. We deliver three types of vaccination machines: LV-2X, LV-4 and LV-6. LV-2X, LV-4 and LV-6 have 2, 4 and 6 vaccination chambers with separate alarms and counting functions. Maximum capacities are ca. 4500, 9000 and 12000 fish per hour for LV 2X, LV-4 and LV-6 respectively. Fish size: 30-600

Lumic Anaesthetic Machine Using both hands the operator places the fish with the head first into two troughs. The fish slides down together with water to the vaccination chamber. On the way down the channel the fish turns automatically into swimming position. During the time in the vaccination chamber the fish will be held stable by the means of two plates, one each side, and injected by a needle through an opening in the chamber. When the vaccination is completed a sluice will open and the fish will be let out. At the same time, the inlet sluice will open and let a new fish into the chamber. This sluice system prevents two fish being in the chamber simultaneously.

OXYGUARD CO2 ANA-

OxyGuard Portable CO2 Analyzer

OxyGuard Portable CO2 Analyzer Portable CO2 measuring and logging The OxyGuard CO2 Portable is a reliable and easy to use instrument that measures the free dissolved carbon dioxide concentration directly in the water. The CO2 concentration is shown on the display and there is an analogue output. A version with built-in data logger is available. The OxyGuard CO2 measures the free dissolved CO2 directly and is not affected by carbonates or other dissolved substances.

It is the free dissolved CO2 - in other words the CO2 gas partial pressure - that affects the fish. The OxyGuard CO2 thus gives simple, continuous and direct measurements of the amount of carbon dioxide in the water that will affect the fish. The analyser is easy to calibrate using the front panel "slope" and "zero" adjustments, after which you just put the probe in the water and measure. Calibration intervals are long, and the OxyGuard CO2 does NOT need regular maintenance.

Monitoring Systems OxyGuard 8 System MODULAR CONSTRUCTION There are two sizes, OxyGuard 6 or 8. These can be fitted with up to 6 or 8 transmitters. It is possible to begin with a single measurement and expand later – this can be performed by the user. You only pay for what you need! REGULATION AND CONTROL Each channel (measurement) has a change-over contact to control diffusers or other dosing equipment. ALARMS There is an extensive alarm system, with individual low alarm, common high alarm and common low alarm contact outputs. The common alarms will also trigger on power failure. SAFETY The above alarm functions give good security. The units can also, as standard, be connected to 24 VDC, e.g. from a battery. Change-over will automatically take place if the mains supply fails. If a fault in one channel occurs the rest will carry on working – and the fault can easily be rectified by changing a transmitter. DATA COLLECTION & RECORDING CONNECTION Can easily be performed by making connection to the analogue output signals. OXYGEN, TEMPERATURE AND pH OxyGuard systems can also be used to measure, monitor and control temperature and pH as well as oxygen – mixed in the same system. GALVANIC ISOLATION Each input is galvanically isolated from all other circuits. This ensures good noise immunity and reliable measurement.

OxyGuard MultiLog The MultiLog is designed for use with the older OxyGuard 6 and OxyGuard 8 units, but can be used for other instruments. MultiLog is a data logger with a maximum of 8 channels. As well as storing values, the MultiLog can be used as interface between instruments like the OxyGuard 8 and a PC, so that real-time measured values can be seen on the PC.

Monitoring Systems OxyGuard Atlantic The OxyGuard Atlantic is an accurate, reliable and easy to use oxygen meter with features ideal for use in aquaculture facilities such as shrimp farms, carp farms and other installations with individual large ponds. It measures both dissolved oxygen and temperature and has 4 relay outputs. The dissolved oxygen measurement is compensated for atmospheric pressure, which permits accurate control of aerators. The user can link setpoints to parameters as desired. Setpoints can then be linked to output relays. It is also possible to link setpoints together. This permits, for example, an aerator to be started both from a DO setpoint and a temperature set point. mg/l (ppm), % saturation and oC The Atlantic has a barometric pressure sensor, and the probe incorporates a temperature sensor. This gives you correct values of dissolved oxygen in both mg/l and % saturation. And, of course, you don't need a separate temperature measurement. Safety First! The Atlantic has four relay outputs and 8 set points. There will always be at least one relay output that can be used to give an alarm if the oxygen level goes too low or the temperature too high. And since Atlantic measures both parameters and has logical linking you only need to use one relay. Timer functions The Atlantic has 8 timers that can be used for a number of purposes. For example, alarm can be delayed so that only a sustained fault results in alarm being given. Precise measurement in salt water Most users will find that manually setting the salinity for their Atlantic meets their requirements. However you can connect an Oxyguard salinity Meter and The Atlantic will compensate automatically.

OxyGuard OxyLog The OxyLog measures oxygen and temperature in the environment The OxyLog consists of a battery powered data logger with displays in a sturdy cabinet and a combined oxygen and temperature probe. It can be chained to a tree or post â&#x20AC;&#x2022;in the wildsâ&#x20AC;&#x2013; and be left to monitor and register values of dissolved oxygen and temperature for months. The PC software that is included in the package makes it very easy to transfer values and to observe what happened when. Description OxyGuard Atlantic OxyGuard OxyLog

 Unsurpassed overview and security  Total Control-Oxygen injection, heating, pumping, everything!  Easy to optimise operation  Only a single data cable for all signals  LAN connection as standard  Access the system from anywhere!  Wireless LAN for even more freedom and flexibility  Easy integration with other systems. The OxyGuard Commander is a process control system specially designed to perform the functions necessary in a fish farm. Water quality monitoring and control is the main task, but Commander has practically unlimited capabilities. Commander combines newly designed input and output units and software with a tried and tested bus network to provide both small and large farms with a very economic solution that is easily and precisely adapted to your exact needs.

Monitoring Systems Via a PC running the main Commander program connection is possible both to other field bus systems and other computers. The latter can be performed through the office network or through the internet. A Commander system can thus become a part of the overall data system of the fish farm, enabling operation to be finely tuned to market demand trends to give a strategic advantage.

Ease of Use User friendly PC display to control your site from the office.

Commander systems can, just like the traditional OxyGuard multi-channel systems be extended and adapted, but the Commander provides possibilities far beyond the scope of any traditional system. There is no limit to the number of channels that can be incorporated, just add the units you need, and the system can be divided into sections that will function alone even if connection to the rest of the bus network is broken. Wiring is greatly reduced since input and output units can be placed close to where the actual measurements are made or to where control is effected. The Commander Probe is an improvement on previous OxyGuard probes. You no longer need to choose between mg/l and % saturation. The Commander gives you both. Temperature probes are no longer required, as the Commander also measure temperature. The Commander Probe is as near maintenance free as modern technology permits.

Sterner AquaTech UK can provide servicing on Commander Probes. Contact us today for information.

Water Filtration HydroTech DrumFilter Micro-screening is an efficient and reliable technique for separation of particles from all kinds of liquids. Hydrotech develop and manufacture high performance filters for water purification and product recovery. The Hydrotech Drumfilter is a mechanical and self cleaning filter specially designed with a view to achieving high performance in systems where it is essential to prevent the particles from fragmentation. The filter works without pressure and is robustly designed with few moving parts to ensure long life and low maintenance costs. HydroTechâ&#x20AC;&#x2122;s patented filter elements greatly simplify both the replacement and change of the filter opening size. The drum is constructed in sections, each with three, four or five filter elements depending on diameter. This facilitates maintenance and makes it easy to adapt the filter to actual need of flow capacity and performance requirements of filtration. The HydroTech Drumfilter is specially suitable in fish farming systems where it is essential to prevent the particles from fragmentation. Both in re-circulated systems and in open systems for intake and outlet water.

HydroTech DiscFilter The Hydrotech DiscFilter is a range of micro screens for solids removal and product recovery. The disc design is particularly advantageous when a large filter area is needed. The compactness of the disc filter configuration result in 2-3 times more filter area compared with drum filters with same external dimensions. This makes the Hydrotech Disc filter a good choice for recirculation systems, effluent polishing of waste water, fine filtration of intake water, or other applications where a space -saving filter with fine filter openings and large filter area is required. In normal operation the disc filter is approximately 60 % submerged and the head loss across the screen varies between 50 and 200 mm. Maximum allowable head loss in continuous operation is 300 mm. Back-wash and rotation can be continuous or controlled by an SS or 316 SS. titanium or special alloys. Filter cloth is made of polyester or 316 SS.

Water Filtration HydroTech BeltFilter The Hydrotech Beltfilter is made for efficient filtration and draining of sludge and wastewater. It is an automatic, selfcleaning filter specially designed to achieve optimal performance in systems where high solids content in the dewatered sludge is essential. Sludge or wastewater is led into the filter 1 and passes by gravity through the filter belt 2. The belt is designed as a slowly moving conveyer installed in a stainless steel tank. As the water passes through the filter, the filtering process ensures the efficient removal of particles. These particles are drained on the belt to a high dry matter content. The dewatered sludge is removed at the top of the filter 3 and discharged through a hopper 4 for final treatment. Backwash System: Dewatered sludge is scraped off the belt which is then cleaned by a high-pressure water rinse system. (backwash unit retracted for visibility). The belt is further cleaned by a highpressure backwash system 5 and the rinse water is led either back to the process or to further treatment. The Belt filter is normally operated intermittently (demand) controlled by a level switch.

Bernoulli In Line Self Cleaning Filter Bernoulli AB develops and delivers self-cleaning filters for continuous filtration of liquids in pressurised systems. These can be used to remove sediment and debris from natural water sources such as sea or river water, or to remove particles from process liquids. Our filters harness the power of a natural physical phenomenon, which leads to an ingeniously simple but highly reliable filtering operation.

The Bernoulli cleaning principle In a Bernoulli filter, the bulk of the work is done by a disc mounted on a pneumatic cylinder. The filter basket is cleaned by this disc as water passes through a gap between the disc and the basket. Flow velocity increases locally around the disc and, in accordance with the Bernoulli principle, the static pressure is reduced. It is the vacuum effect of lower static pressure around the edge of the disc that cleans the basket. Advantages  Simple and ingenious cleaning system with few moving parts, ensuring high operational reliability and simple maintenance.  A low and constant pressure drop, the same in both clean and dirty conditions.  Low flushing pressure: from 0,3 bar g.  Easy installation: the Bernoulli Filter can be fitted directly to pipelines. Any horizontal or vertical position is possible.  Good corrosion resistance: filter bodies in PVC and glass fibre reinforced polyester (GRP) are particularly suitable for corrosive sea water, stainless steel filter bodies for fresh water applications.

Oxygen Injectors Oxygen Production AirSep Oxygen Generators eliminate the expense, inconvenience, hazardous handling and storage problems often associated with purchased liquid or high pressure oxygen. The 13 standard models AirSep offers are the most efficient and dependable generators available today. Fully automatic, they require no specialized operating personnel. Simply connect an air compressor to the generator and your oxygen distribution system to the generators oxygen receiver. Then connect the power cord to a grounded electrical outlet, turn the unit on, and set your oxygen delivery pressure. A simple on-off switch supplies oxygen whenever you need it.

Why a PSA and not a VSA system ? 1. 2. 3. 4. 5. 6.

PSA produces oxygen which is stored in a holding tank, this allows the system to deal with a crash situation which is common in aquaculture. PSA is not running 24 hours a day seven days a week, both compressor and generator go on stand by when storage tank is full and comes on has tank is been used. VSA booster has to run all the time to maintain pressure which makes running costs between systems negotiable. PSA uses two way solenoid valves since they have proven to be significantly more reliable than 4 way solenoids used in VSA. PSA can produce oxygen up to 5 bar directly, VSA has to use an oxygen booster which can produce up to 3.4 bar, are very complex and require more maintenance than standard compressors. PSA produces produce oxygen at high level of purity(92-94% ). Airsep PSA systems have hundreds of references in the aquaculture industry.

Oxygen Injectors OxyTech OXYTECH is a well proven system for in line, large scale oxygen enrichment of water. Oxytech has been invented and designed for aquaculture by us.

High capacity Oxytech is a vacuum driven mixing unit for total oxygen enrichment of the water flow. This method is often recommended because the efficiency always will stay at its maximum. Enrichment can be done either on the main water line or on the individual pipes to the fish tank, with separate regulation. In addition to the gross enrichment of the water it is recommended to adjust the oxygen level in the individual tank with diffuser elements, based on direct measurement in each fish tank. This also adds extra security in the case of circulation failure or pump stop.

Very economic Oxytech works by taking out a separate flow which is enriched in a special venturi process. This mixture further goes into a vacuum chamber where the oxygen is left to dissolve properly. Because the chamber is pressurized the water will be super - saturated. All surplus gas is collected at the top inside and is well remixed through an injector system. This recycling ensures a high efficiency and a rich solution of both dissolved gas and microscopic bubbles. The efficiencyâ&#x20AC;&#x2122;s will in practical terms be 100 %.

Low pressure = low cost Oxytech operates at a relatively low pressure, which is good for two reasons. Principally the energy costs for operation will be low. Secondly - Oxytech can make use of all types of oxygen supplies. This adds freedom to choosing the source of oxygen, and even to save even more by producing oxygen on site.

Since 1993 For two decades we have installed a large number of Oxytech systems on fish farms. Hands on experience with instalment and operation has given us very useful feedback, which has been incorporated into the design. At a great number of fishfarms, Oxytech contributes significantly to savings, higher production output and net returns. Complete installations Sterner AquaTech delivers complete systems for automatic oxygenation of water, with control and monitoring systems included. We deliver systems both for total oxygenation and direct oxygenation in the fish tanks, separate functions and parts, with oxygen generators, systems for distribution, as well as integrated monitoring for bio-economic management. An increasing number of fish farms make the use of oxygen produced on site, and all records prove increased profitability.

Oxygen Diffusers Point-Four Trac Lock Diffusers Point Four Trac-Lock diffusers are an economical alternative to the Point Four MBD’s (Micro-Bubble Diffusers). Like the MBDs, they are good for use with pure oxygen or carbon dioxide for Aquaculture applications. Their modular design allows for greater flexibility and the plastic base eliminates the possibility of corrosion. The flat plate design ensures bubbles across the entire surface. The slim design will not hinder fish netting and is ideal for Fish Transportation systems. The ―twist and lock‖ design allows for easy diffusing area adjustment or for simple removal of sections for cleaning or servicing. The Trac-Lock diffuser delivers a high gas absorption efficiency, depending on the submerged depth, flow rate, and dissolved oxygen concentration. Typically 40% to 50% at 1 m depth; can be as high as 80% or even 100% at depths of 6m or more.

Point-Four Wedge Lock Diffusers WEDGE-LOCKTM is a modular system of diffusers and end sets that fit together to form a bank of up to eight units. Oxygenation capacity can be increased (or decreased) as your needs demand by simply changing the number of diffusers used for greater flexibility and minimal downtime. Designed for total ease of use, WEDGE-LOCKTM modules Twist and Lock together to form an air-tight seal without the use of tools. Hose with push-in fittings connect the diffuser banks to the gas supply, significantly reducing set-up time and effort. Manufactured from tough plastic WEDGE-LOCKTM will not corrode and is resistant to the ultraviolet rays from the sun. The diffusers streamlined wedge shape improves stability in tanks with high water flow and offers less resistance in self-cleaning tank systems. WEDGE-LOCKTM uses an ultra fine pore ceramic producing a high Absorption Efficiency (AE) allowing you to increase yield while controlling the cost of expensive gases.

Point-Four Micro Bubble Diffusers One of the simplest ways to dissolve gases, such as oxygen or carbon dioxide, in water is to introduce the gas as small bubbles the smaller the bubbles the more efficient the absorption of the gas. The Point Four microbubble oxygen diffuser produces a cloud of extremely fine bubbles - 100 to 500 microns. This is much finer than graphite or carborundum diffusers porous hose and because the diffuser is flat, the bubbles do not coalesce as with circular section diffusers. The Point Four diffuser uses an ultra fine pore ceramic plate which ensures uniform bubbles across its entire surface. The ceramic is a clean and inert material.

Oxygen Diffusers Bio-Weave Diffusers Self-weighted Bio-Weave diffuser hose is a popular method of introducing air and oxygen into hauling tanks, culture tanks, lakes or wherever long flexible diffusion is needed. It's made of a strong, woven Dacron material that will last for years. Operating range is 0.2–0.6 cfm per foot. The diffuser surface is a soft fiber that flexes easily. Because Bio-Weave is self-weighted, placement and removal of these large diffusers is simple. We make these medium-bubble diffusers with garden hose fittings (a cap on the male end and a 1/4inch male barb adapter on the female fitting). Bio-Weave has about a 20‖ H2O resistance to air flow, so it is marginally compatible with regenerative blowers. Ship weight is about 1 lb/ foot. Note: Diffusers are also known as airstones.

CO2 Degasser

STERNER CO2DEGAS-

CO2 Degasser Can improve production by improving flow currents in tanks generating more oxygen whilst removing CO2, offering lower energy consumption and reduced running costs.

Sterner CO2 Degasser Lower Energy CO2 Remover New CO2-aerator makes it possible for big reduction in water consumption Reasonable use of oxygen within land based fish farming has as known increased the capacity of site considerably. The key to further efficiency is to reduce and re-use the water. At Vik Settefisk, near Bergen in Norway has a new CO2 Aerator which has been on a recent trial. The aerator was tested during normal running at the site, by a specific water consumption at 0,1/l/ new water/kg.fish/min. the CO2 level was reduced from 21 mg CO2 to 10 mg. CO2 in the fish tank (this corresponds to a reduction at more than 50%).

The water is supplied with a large amount of O2 during the aerator. Samplings done by the site manager Bjarte Landro shows 75 % saturation in to the aerator and 95% saturation out of the aerator. By good O2 regulation in the tanks at approximately 75% saturation is it a lot of O2 that aerates in to the water. Calculations show that the value of the O2 that the aerator adds to the water covers the electricity expenses for the aerator. The trials were carried out during one week in September 2008. Bjarte Landro observed the fish during the trial period and confirms that both the growth and the appetite were very good during the whole period.

Water Treatment WEDECO Tak 25 & 55 Wherever waste water can enter water used for bathing or drinking, or when waste water is to be recycled - e.g. in agriculture, targeted disinfection of the waste water is necessary. The modularly designed UV system WEDECO TAK 55 allows practically unlimited quantities of waste water to be disinfected - absolutely safely and energy-efficiently. The UV system WEDECO TAK 55 is ITTâ&#x20AC;&#x2122;s solution for safe, more environmentally friendly waste water disinfection. The philosophy behind WEDECO TAK 55 is absolutely reliable operation and objective performance for long-term deployment. The system has been validated according to standards recognised across the globe such as NWRI and US EPA. The WEDECO TAK 55 UV system has been specially developed for the disinfection of waste water from clarification plant processes. Installed within the effluent channel, the modular, compact construction of the TAK plant allows for the treatment of practically unlimited flow quantities.

WEDECO BX The reactors of the WEDECO BX series are equipped with efficient high-performance low-pressure SpektrothermTM UV lamps. In combination with special flow installations for the improvement of hydraulic conditions, very good disinfection results are achieved with low energy consumption at the same time. Vario dose control: Less energy consumption - longer emitter running times The SpektrothermTM lamp technology does not only enable an increased UV-C performance, but also a variable controlling of the lamp power from 50 - 100%. This development makes using the modern dose control possible, which leads both to a reduction of the energy consumption and to extended emitter lifetimes. Automatic wiping system reduces deposits BX UV systems are already designed for fast and simple maintenance, e.g. through simple disassembly with manual cleaning or the standard integrated chemical rinsing system. In addition, WEDECO BX equipment can be optionally fitted with an automatic wiping system, which prevents the formation of organic and inorganic deposits on the protective quartz pipes. Therefore interruptions to operation are practically ruled out thanks to manual cleaning of the emitter cladding pipes. The chemical-free wiping system works with PTFE viton wiper rings, which are not impaired themselves by the intensive UV-radiation at the emitter surface.
