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 production 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 bishexamethylenetriamine, 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 bishexamethylenetriamine is approximately stoichiometric. The composition is maintained in the system for sufficient time to effectively clarify the system without production of an uncontrollable floc.
