Abstract
An improvement in a process for the separation of aqueous paint spray mists from the environment of a paint spray operation employing a water rinse technique is described. According to the improvement, rinse water is mixed with a water-soluble, substantially non-volatile, low molecular weight, salt-like electrolyte in a quantity sufficient so that the specific weight of the aqueous salt solution at 20.degree. C. is at least 1.01. The electrolyte solution causes the paint to coagulate from the water mixture for convenient separation by decantation, filtration, or the like.

In a process for the separation of spray mists of water dilutable paints from the environment of a paint spray operation employing a water rinse or wash technique, the improvement wherein in rinse or wash water used to rinse the spray shops and/or wash the spray mist is mixed with a water-soluble, substantially non-volatile, low molecular weight, salt-like electrolyte, said electrolyte being present in an amount sufficient to provide an aqueous salt solution which, at 20.degree. C., has a specific weight of at least 1.01, causing paint to coagulate so as to permit separation from the rinse water in known manner.
