Advantages
Small purifying plants are used for the purification of waste water from toilets, bathrooms, kitchens and similar sources of pollution from houses and other residential facilities.
1. Reliable functioning – no smells or malfunction. Water purification in the treatment plant is simple, as all its features s and drives function according to the principle of air – sub-pressure (mammoth pumps).
EU Directive
2. 24h service – maintenance and servicing done by ROTO's experts. We provide advice on a suitable location, supervise the entrenchment, monitir out the start-up, repair the purifying plant, etc.
According with the EU Directive, every building must be connected to the sewage network system or provide its own treatment by year 2015. In cases where a connection to the sewage system is impossible or is too expensive, the most rational investment is to install a purifying plant.
Determining the size of the purifying plant The size of the purifying plant is determined by population units (PU) or equivalent users, while at the same time defining the biochemical capacity of the treatment plant. The PU unit signifies the specific consumption of water ranging from 0.15 to 0.20 m3/person/day and the biochemical load of 0.06 kg BNO5/person/day. Only waste water coming from households and toilets without the inflow of rainwater can be led into the purifying plant.
3. Fast delivery – ROTO is a manufacturer, because of this purifying plant is manufactured and delivered in a few days. 4. Easy to install – the purifying plant can be installed in a few hours. A pit is dug, the treatment plant installed, the waste water inflow from the house is connected, the timer is connected to the tank and the computer is turned on. The burial instructions are enclosed. 5. Low operating expenses – the annually cost of the consumed electric energy amounts to only €6.1 per person. This expense can be reduced by the installation of a photovoltaic system. 6. High purification capacity – The ROTO purifying plant purify water up to 97.2%. 7. Water purified by a treatment plant can be reused for watering garden. 8. Economy – Investment in purifying plant is repaid in period of five years. 9. Long life – the purifying plant’s tank is made of polyethylene and has a life of 50 years. 10. 100% recyclable – after using it, the treatment plant may be disassembled and its polymer components may be recycled.
Conformity of treatment plants ROTO's small purifying plants are made according European SIST EN 12566 standard and bear the marking CE. The ROTO purifying plant received the Building and Civil Engineering Institute of Slovenia's quality mark. ROTO Purifying plant has received quality label Engineering Institute Slovenia.

INFLOW of waste water
COMPRESSOR • The device functions completely without moving mechanical parts (pumps, sliders, cylinders, etc.). • The compressor is the only machine element. • It supplies air to bacteria in order for them to survive and process waste water into pure water. • It works quietly; 9 hours per day on average.
OUTFLOW of waste water

COMPUTER Purifying plant is controled by a computer (microprocessor), allowing the following advantages: • All elements are digitally supervised; inaccurate functioning is detected automatically. • The computer can be set to holiday functioning.
The bacteria survive for a few days even if there is no waste water inflow. The electronic equipment is installed into a special place in the house or in an external box.
Air blowner
Waste water purification process The house purifying plant control is supervised by a computer built in a box or, for example, in a basement or in the garage, next to the compressor. The computer contains set times for the functioning of individual phases. The computer controls 4 valves, each with their own function:
1. Pumping water from the mud chamber to the aerator chamber. 2. Aeration in the aerator chamber. 3. Pumping the purified water from the small purifying plant into the outflow. 4. Pumping the sedimented mud from the aerator chamber back to the mud chamber.
Upon anticipated longer absence (more than a week), we can set the small purifying plant to holiday regime via the computer. During this time, only the necessary ventilation of biological functions is carried out.
1. The waste water flows into the spurifying plant in free fall and is collected in the first chamber (mud collector). The mud collector accumulates waste water coming from the house.
2. From the mud collector, the compressor, working on sub-pressure, pumps through a certain amount of toilet water into the aeration chamber. In the process of pumping through, the computer turns on the first valve.
3. Air (micro bubbles) is supplied through the compressor into the aeration chamber, where the decomposition of toilet water is carried out by means of bacteria. The compressor supplies air through the other valve and the membrane into the small treatment plant. The aeration time depends on the size of the small treatment plant.
4. After the aeration is finished, the mud sedimentation phase in the aeration chamber begins. The purified water on the surface is separated from the sediment. In the sedimentation phase, the compressor doesn't work.
5. The purified water is pumped out (on sub-pressure) from the aeration chamber by means of the compressor (the third valve is activated).
6. The purified water is pumped out (on subpressure) from the aeration chamber by means of the compressor (the third valve is activated). The purification procedure is repeated four times a day.

Waste water treatment procedure The sediment-selective chamber (the SS chamber) is a flow chamber of the purifying plant, into which flow the household discharges that will be biodegraded. The discharges, mixed with active mud, move through the opening at the bottom into the aeration-activation chamber.
Into the aeration-activation chamber (the AA chamber), air is supplied by means of a ventilating fan and is lifted in small bubbles through aerators installed at the bottom of the device to the surface. The AA chamber enables the biological process of water purification with bacteria and air. The bacteria have enough oxygen and feed on waste supplied from the SS chamber.
Separation chamber (the S chamber): A mixture of mud comes from the AA chamber to the separation chamber, where the separation of the purified water from active bacteria takes place. The active bacteria sink to the bottom of the S chamber, from where they are pumped to the beginning of the process, while the purified water flows out into nature. The mud mixture, which can also be used as fertilizer, must be pumped out twice a year. We provide expert assistance in treatment plant maintenance.

User advice
Tips for user of Purifying plant Treatment plant maintenance The buyer or maintenance staff are obliged to maintain the smallpurifying plant in line with the enclosed instructions. In order to supervise the functioning, the customer may sign a contract on the small purifying plant for maintenance with the manufacturer. The purifying plant cleaning takes place once a year, depending on the load and the size of the small purifying plant.
PURIFYING PLANT START-UP Start-up can be carried out by the users themselves or with the help of the ROTO company. The biological matter forms itself after two to three months of use.
MAINTENANCE WORK UNDERTAKEN BY THE USER This comprises of cleaning work and control over the functioning of the entire hardware. The results of all controls must be entered into the operationallog. The control is carried out visually, more often at the beginning and less frequently later. Weekly control: Verifying whether the compressor works (small purifying plant – green light, eko6 – compressor's sound). Monthly control: Fasten a 1.5l cut plastic bottle onto one end of a stick that is at least 1.5 m long. Once aeration is underway, take a sample of the toilet water (small purifying plant -second chamber, eko6 - middle chamber) and pour it into the 1l measuring cylinder with markings for millilitres. Then, wait for 30 minutes and read out the sedimented part. The sedimented part is where the bacteria is. The purifying plant’s functioning is optimal when the bacteria becomes brown and the amount ranges between 30 and 70 ml/l. Using a stick, we can check the thickness of the formed paper crust, etc. in the first chamber. The crust must be removed when it exceeds 20 cm (we must call the municipal utility company). Annual maintenance work: The crust must be removed once a year. If there is no crust, or if the crust is thinner than 20 cm, the annual maintenance is not necessary and can be done every two years. CAUTION: If we wish to establish healthy bacteria for the plant to function optimally, we must take care of the bacteria by NOT using cleaning agents and other substances containing chlorine, chloride, sodium hydroxide or potassium hydroxide. All cleaning agents containing hydrogen peroxide, alcohol, ethanol or methanol can be used with the purifying plant but it is better to use cleaning agents that are labelled as biodegradable and environmentally friendly. Throwing wet wipes, cotton buds, cotton wool or other similar non-biodegradable hard particles into the purifying plant in not allowed.
