Abstract
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.
Claims46
A method for clarifying water or removing phosphate from water, comprising:
- adding an aluminum-containing coagulant selected from polyaluminum chloride, aluminum chlorohydrate, polyaluminum chlorohydrate, aluminum sulfate, sodium aluminate, polyaluminum sulfate, polyaluminum silicate chloride, polyaluminum silicate sulfate or a combination thereof, and a synergistic amount of a natural, non-charged polysaccharide to water containing matter;
- forming agglomerations in the water comprising the matter, the aluminum-containing compound, and the polysaccharide;
- and
- removing the agglomerations from the water to remove the matter from the water.
