Water Treatment compositions comprising a coagulant containing Aluminium and not a natural polysaccharide Derivative, where the relationship between the polysaccharide and the coagulant is between 1: 10 to 1: 100; and Methods of use.

摘要

Methods for clarifying water, reducing turbidity of water, and removing phosphate from water include adding a water treatment composition having an aluminum-containing coagulant, and a natural non-charged polysaccharide, such as guar. The aluminum-containing compound can include polyaluminum chloride, aluminum chlorohydrate, polyaluminum chlorohydrate, aluminum sulfate, sodium aluminate, polyaluminum sulfate, polyaluminum silicate chloride, polyaluminum silicate sulfate, or a combination thereof.
