ABSTRACT:
The invention is a water treatment composition comprising at least one phosphonamide and blends thereof and a method to treat water. As phosphonamides are generally odorless, and typically solids, phosphonamide and phosphonamide blend compositions are generally odorless, conveniently processed and manufactured, and safely used without risks of exposure to odors and vapors associated with the corresponding amines. Advantageously, phosphonamides blended with amino-phosphate esters provide useful treatment compositions. The inventive compositions are generally used to treat water contained in water flow systems such as boilers and cooling towers.
