Abstract
A novel method of treating circulating water containing over-sprayed water-based or solvent-based paint, such as in a paint spray booth operation, comprises adjusting the alkalinity of the paint spray booth water by adding an alkalinity source thereto, contacting the oversprayed paint with the alkalinity-adjusted water and with an alumina coated silica sol added to the water, adding an effective amount of a polymer floccing agent to the water, and removing resulting sludge from the water.
