Elimination of laquer sludge
In paint application devices, booths and chambers with water-based waste air purification systems, waste is generated in the form of lacquer sludge, i.e. emulsion of the residues of paint in the purification system water. To eliminate lacquer sludge from the technological water flows, we have developed batch or continuous process purification plants applying neutral absorption techniques. The plant pumps polluted water from the lacquering chamber into a reactor, in which a metering system admixes coagulant to increase the size of floccules.
Waste sludge may take the form of suspended or sedimented waste and is separated out of water by means of skimming or passing through a belt or bag filter. After purification, water is pumped back into the booth-chamber reservoir. With highly loaded plants, upgrading with a filter-press is recommended.
Neutralisation of waste water
With chemical pre-treatment of surfaces, diminishing effectiveness of chemical media leads to waste technological water. We offer batch or continuous purification-neutralisation equipment for such waste water. The equipment specifications may meet the general, statutory criteria for water effluent into the sewage network; alternatively, equipment meeting higher criteria is available on request.
The construction of the purification-neutralisation is adjusted to the type of waste water.
