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. |
