METHOD AND ADDITIVE FOR CLARIFYING AQUEOUS SYSTEMS WITHOUT PRODUCTION OF UNCONTROLLABLE FLOC ABSTRACT Method and additive are provided for clarifying an aqueous system which may contain an oil-in-water emulsion, a dispersion of a non-aqueous discontinuous phase, without pro- duction of a resultant uncontrollable floc in the system, by contacting the system with an effective water clarifying amount of a composition having present a dithiocarbamate of bishexa- methylenetriamine, said dithiocarbamate having the formula: Image wherein: R is hydrogen, an alkali metal, an alkaline earth metal, ammonium, ion or an amine, the ratio of carbon disulfide to primary amine for said dithiocarbamate of bishexamethylene- triamine is approximately stoichiometric. The composition is maintained in the system for sufficient time to effectively clarify the system without production of an uncontrollable floc.
