The treatment of waste water consists of systems for the separating and drying of paint sludges by the painting booths’ recirculated water.
The paint overspray is collected by the water that flows on the bottom of the painting booth and is carried towards a decanting pit, inside of which doses of chemical products are added that encourage the paint to float to the surface and accumulate.
The sludges produced are subsequently separated mechanically from the water that can then be reused as a means of separation on the floor of the Hydrospinplus booth. The treatment pits can be separated according to paint product or, depending on the products applied, they can collect the water originating from several painting booths.
The paint sludges produced can be subsequently dried to reduce the concentration of water and the related volume and weight.
