Why purify waste water in this sector?
Download brochure
  • Waste water is extremely contaminated due to the presence of surfactants, COD and suspended materials

  • Disposal with no purification has high costs

  • There is the obligation to manage waste water in compliance with the law


More informations:

The production of wall paints or similar water-based products entails frequent washing of production equipment such as:

  • Preparation tanks (stationary or on trolleys)
  • Sundry equipment (spatulas, paintbrushes, small containers)
  • Reactors where the water-based paints are prepared
  • Production premises in general


The water used to wash this equipment therefore generates waste water containing various polluting substances, organic and not, released by the residues of the paints.

A specific treatment is required to remove these pollutants, so that the purified water may then be conveyed to the drain, in compliance with current Anti-pollution Regulations (ref. Legislative Decree no. 152 of 03/04/2006).

All proposed installation solutions feature:

  • Tailored plant design and implementation
  • Extreme ease of operation
  • Balanced operating costs
  • “Single block” constructive configuration pre-assembled in the Works
  • Extremely compact overall installation dimensions
  • Simplified system management
  • Management autonomy after suitable training
