Abstract:
An improved process for the decontamination and deodorization of waste waters selected from the group consisting of: livestock wastewaters, slaughterhouses waste waters and livestock lagoon water streams, which process comprises adding to said waste waters a composition comprising a sufficient amount of an acid to lower the water pH to 3.0 or less than 3.0; and wherein said acid is selected from the group consisting of a 1,3,5-Triazine-2,4,6-(1H,3H,5H)-hydroxyalkyltriglyoxilic acid of the formula ##STR3##2,2-ether diglycolic acid, and sulfamic acid, wherein said composition comprises: (a) from 1 to 40 parts by weight (pbw) of said acid; (b) from 0.5 to 20 parts of a coagulant selected from the group consisting of inorganic coagulants and inorganic flocculant-coagulants; (c) from 1 to 10 parts of an alkaline compound; (d) from 1 to 6 parts of a water soluble amine selected from the group consisting of water soluble polyguanidine resins, water soluble polymelamine resins, water soluble cationic alkyl polyamines, water soluble alkyl polyamines, polyethyleneimines, mixtures of two or more of these amines, and mixtures of one or more of these amines with one or more water soluble inorganic coagulants; (e) from 2 to 50 parts of one or more organic modified clay; and (f) from 0.5 to 10 parts of an organic flocculant selected from the group consisting of: polydiallyldimethylammonium chloride (PDADMAC), cationic copolymers of acrylamide, anionic copolymers of acrylamide, nonionic copolymers of acrylamide, and mixtures thereof; wherein said organic flocculant has a Viscosity Molecular Weight range of from 10,000 to 30,000,000.
