ABSTRACT OF THE DISCLOSURE Inorganic-organic alloy,organic blands,polymer compositions for waste water treatment, having the formula: A ? B+ ? C ? D+ wherein A is from 0 % to 98% by weight of the total alloy composition, and is selected from the group comprising: polyhydroxyaluminumchloride, hydroxyaluminumchloride, polyhydroxyaluminumagnesiumchloride, polyhydroxyalumi- numagnesium sulfate, polyhydroxyaluminumagnesiumsulfate, hydroxyaluminum- sulfate, polyhydroxyaluminumzincoxidechloride, polyhydroxyaluminumchloro- sulfate, polyhydroxymaynesiumchlorosulfate, polyaluminumferricchloride, polyaluminumferrouschloride, polyaluminumcholridesulfate, polyhydroxyaluminum- chloridesilicate, polyhydroxyaluminumsodiumsulfophosphate and aluminum salts; B+is from 0 to 100% by weight of the total alloy oomposltion, and is selected from the group comprising polymers or resins made from guanidine, dicyandiamide, or cyanoguanidine compounds, copolymerized with cationic charges, multiple organic cationic charges, protonized agents, alkylamines, alkanolamînes, alkyl, or hyaroxyalkylguanidine, or any mixture thereof; C is from 0 to 100% by weight of the total alloy composition, and is an aqueous solution of cationic resin mixed with a reagent selected from polyalky- lamines, polyethylenepolyamines, N-substituted ethylenelmines, polyquaternary compound, 1,3-bisquaternaryammonium compound, polyquaternaryalkylamines and melamine-formaldehyde protonized or quaternized; D+ is from 0% to 95% by weight of the total alloy composition, and is selected from the group comprising aqueous solutions of the quaternary ammonium compounds like PDADMAC,or cationic (co) polyacrylamide,or as homopolymer POLYDADMAC melamine formaldehyde alloy, Manich type, (co)polyacrylamide melamineformaldehyde alloy polymers, incorporated therein. and provided that at least one of A, B+, C , D+ is positive. Methods for making the compounds are also disclosed.
