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.

1-46. (canceled)
A water treatment composition, comprising:
- 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 natural non-derivatized polysaccharide selected from guar, locust bean gum, gum arabic, gum tragacanth, starch (branched and linear), agar, carrageenan, pectin, xanthan, konjac, cellulose, chitin, a galactomannan, glucomannan, α-D glucan, xyloglucan, arabinoxylan, insulin, linear polysaccharide of alternating α-(1-3)-and α-(1-4) galactopyranose units, linear polysaccharide of glycosidically linked units of α-D-glucopyranose, linear polysaccharide of glycosidically linked units of α-D-glucopyranose, and heteropolymer of glycosidically linked units of both α-(1-4)-2-acetamido-2-deoxy-D-glucopyranose and α-(1-4)-2-amino-2-deoxy-D-glucopyranose, sodium caseinate, hydrolyzed casein, an aminoacid homopolymer, or polyglutamic acid.
A method for clarifying or reducing the turbidity of drill 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 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.
A method for clarifying or reducing the turbidity of water comprising hydrocarbons, 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 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.
A method for clarifying or reducing the turbidity of water comprising suspended materials from oil or gas drilling or hydraulic fracturing or suspended matter present in water from oil refinery operations, 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 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.
