The removal of suspended solids and sludge dewatering from paint spray booth treatment systems within the automotive industry is an area of specialism for MSE Hiller, which is why leading car manufacturers BMW, Mercedes and Opel, choose Hiller centrifuges to dewater their wastes.

Hiller Decapress decanter centrifuges are used in paint shops to considerably reduce the volume of paint sludges, By reducing sludge volume this has the added benefit of reducing costs for disposal.

Our centrifuges can effectively treat waste from both water-based or solvent-based paint.

The effluent waste wash waters typically contain dispersed acrylate and vinyl resins, dissolved cellulose derivatives, together with residues of pigments and filling agents, dyes, solvents, traces of acids or alkalis from pH-value adjustment - as well as residues of preserving agents.

The sludge obtained by physio chemical treatment which is used to denature the paint effluent after the spray booth is typically stored in an agitated tank prior to being pumped into a Decapress centrifuge. Our centrifuge solutions are capable of handling anything from 300 to 80,000 litres of paint effluent an hour - dependent upon the size of plant used.

The solids discharge is either disposed of or recycled for re-use, while the clarified liquid phase is recycled back into the process, thus reducing costs by minimising the use of fresh water.
