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.
Claims13
A method of producing an aluminum water treatment product comprising:
- a) dissolving an aluminum compound by liquefying a solid aluminum compound in an acid medium at a temperature of about 20° C. to about 125° C.,
- b) reacting the aluminum reaction solution with from about 1 to about 10 weight percent of a phosphorus compound;
- and
- c) diluting the resultant reaction product with water to make a product solution containing about 23% by weight of aluminum as aluminum oxide (Al2O3) and having a basicity of from about 30 to 85 percent.
