Abstract

this invention relates to the purification and clarification of a dyestuff and pigment colored waste water by contacting said waste water with an effective amount of a condensation product of formaldehyde and dicyandiamide, and an electrolyte, to coagulate said dyestuff, and removing the resultant coagulate from the waste water.
