ABSTRACT:
This invention provides a process for clarifying waters and wastewaters by using aluminum salts and/or aluminum polymers and newly formulated high molecular weight quaternized polymers. The aluminum polymers and the high molecular weight quaternized polymers are blended in the water or wastewater to form a flocculated suspension, causing liquid-solid separation. The quaternized polymers have a molecular weight of greater than approximately 1,000,000 and have a viscosity greater than about 1,000 cps at a concentration of approximately 20% in water. Preferably, poly-aluminum hydroxychloride, poly-aluminum chloride and poly-aluminum siloxane sulfate are used as aluminum polymers along with high molecular weight quaternized polymers such as di-allyl di-methyl ammonium chloride (DADMAC), to significantly improve liquid-solid separation in waters and wastewaters. Aluminum salts, such as alums and aluminum chloride, can also be used along with the quaternized polymers to clarify water. In addition, algae can be removed from water by blending at least one aluminum salt and/or at least one aluminum polymer with a quaternized polymer.
