Abstract
Materials such as amines, alcohols, aminoalcohols, ethers and mixtures thereof, including halogenated adducts thereof, have been found to be useful floc modifiers for water clarifiers to form an effective overall water clarifier composition. The water clarifier portion of the composition is a dithiocarbamate. The floc modifier of a particular water clarifier composition need not be the same compound that is reacted with carbon disulfide (CS.sub.2) to make the water clarifier portion of the novel compositions.
