The condition for the quality of paint coatings is, apart from their mechanical properties and resistant, adequate adhesion to the ground to prevent the coating from separating. The adhesion of the coating is increased by chemical treatment of the surface of the parts to be painted. Chemical preparation of the surface requires the use of a properly prepared process water, softened water and demineralised water with appropriate parameters. However, the process generates chemical sewage of variable composition which in most cases makes it impossible to discharge it directly into the sewage system.

Watersystem offers a set of devices enabling preparation of water of required parameters and treatment of sewage to the quality specified by the recipient.
