Fastrip FP: Filter press for filtration of paint stripping baths

FASTRIP FP

FASTRIP FP series filter presses are specially designed for filtering paint stripping baths. Thanks to many years of experience in this specific sector, ALIT Technologies has identified the construction materials and electromechanical components that ensure maximum filtration performance and durability.

FASTRIP FP filter presses are equipped with as follows:

- Automatic-reset hydraulic control unit

- Oversized closing piston

- Hot-dip galvanised steel supporting frame

- PP filter plates

- Pneumatic diaphragm-type filtration pump, compatible with ALIT Technologies’ paint strippers

- Cover, sludge hopper, and drip tray

- ALIT Technologies’ filter cloths and underlays

- EC electrical panel with simple and intuitive interface for managing the filtration cycle.

FLOCCULANT DOSING DISPENSER WITH A VIBRATORY CHANNEL

ALIT Technologies’ flocculant dosing dispensers have been specially designed and sized for the automatic addition of flocculant to tanks containing paint stripping sludge. We offer different sizes of dispensers depending on the type of paint stripping equipment. By means of a special vibratory channel, they enable an ALITFLOCK series flocculant to be reliably transferred from the vibrating hopper to the sludge sedimentation tank, where it is mixed by the pneumatic mixer.

The dosing dispenser’s hopper is equipped with a level sensor that signals when the minimum product level has been reached. It is possible to adjust the automatic dosing parameters by operating directly on the filter press’ panel interface.

• AISI 304 with adjustable feet that can be fixed to the floor

• Vibratory channel

• Flocculant min. level sensor

• Lid and lump-breaking net

• Integrated into the filtration plant management software

• Variable load volume depending on the application (typically in the range 20-100 litres)

SLUDGE SEDIMENTATION AND FILTERED WATER RECOVERY TANKS

FASTRIP FP filter presses are normally connected to a sludge preparation and sedimentation tank and a filtered liquid recovery tank. The sludge mass formed in the paint stripping tank is sucked in and collected in the sedimentation tank. Its design and conical bottom promote the natural settling of sludge, which is then easily sucked up by the filter press pump. The presence of a level sensor allows the filling level of the unit to be adjusted at will according to specific parameters set by the software, either continuously or discontinuously. The tank is equipped with an ATEX pneumatic mixer for mixing ALITFLOCK flocculants. The filtered paint stripper coming out of the filter press is then collected in the recovery tank. This transfer takes place by gravity: therefore, the filter press and its recovery module must be placed close to each other. Again, the presence of a level sensor allows the filling level of the unit to be adjusted at will according to specific parameters set by the software, either continuously or discontinuously. Both tanks are made in AISI 304 steel, they have a conical bottom, and they are equipped with a level sensor, an opening lid, and an outlet valve at the bottom.

• 1” pneumatic pump for filtered water recovery

• Variable load volume depending on the application (typically in the range 100-1000 litres)

SEDIMENTATION TANKS FOR FILTER PRESSES 400

• 1” pneumatic pump for filtered water recovery

• 1” pneumatic pump for sludge suction

Fixed or customisable load volume depending on the application

ALITFLOCK 4840

This powder product can be used to improve the filtration quality and speed of filter presses with paint stripping baths. ALITFLOCK 4840 is to be added and mixed directly into the sludge, before the filter press phase. Its use guarantees much shorter filtration cycles, much drier sludge cakes, and easier detachment from the filter plates.
