Abstract: A method of making a concentrated, stable aluminum compound containing water treatment product comprising reacting an aluminum compound in solution form with a phosphoric acid compound at a temperature in the range of about 15° C. to about 98° C., measuring the aluminum as aluminum oxide content and adding water to the reaction product if needed to prepare a product having an aluminum oxide content of about 10 percent by weight of the solution. The process is particularly advantageous in providing a system for the production of aluminum water treating products by recycling aluminum waste metal such as beverage containers utilizing a phosphoric acid medium.

Abstract: A method of controlling ammonia levels and soluble phosphorus generated from the animal waste in milking parlors comprising applying to the parlor floor an acidic aluminum salt liquid. The treatment effective amount is effective to reduce phosphorus solubility in the manure; reduce phosphorus runoff and/or phosphorus leaching from fields fertilized with manure; inhibit ammonia volatilization from the manure; flocculate solids in the manure; reduce pathogens in the manure; increase the nitrogen content in the manure; and/or reduce acid rain associated with the manure.

Abstract: Animal bedding materials are pre-mixed with a dry blend or a solution of a hydrolyzable metal salt using a mechanical mixer. Ammonia control is more uniform and pH is reduced. Further, pre-mixing improves worker safety due to dust and corrosive chemical reduction in the atmosphere of animal enclosures.

Abstract: A stable activated silica sol is made by reacting sodium aluminum sulfate and a solution of silica. This solution removes suspended particles from aqueous streams rapidly and effectively. The silica sol is stable for many days and thus can be prepared off-site and transported to the point of use. Further, the activated silica or colloidal silica sol solution of the invention can be continuously added to water and waste water streams, or paper making pulps, stocks and furnishes, without danger of solidifying in the transport systems.
