Abstract
Compositions including alum, a smectite material and optionally one or more of a buffer and an algaecide coating or additives for the clarification of bodies of water by removal of dissolved solids, dissolved organic materials and other anions such as fluoride and chloride as well as the removal of total phosphorus from such bodies of water. The compositions are designed to be delivered to concentrated or impounded phosphorus located at the bottom of various bodies of water and may be produced in various physical forms.
Claims55
