Abstract
Polysaccharide agents for removing solids from an aqueous suspension and methods for using the polysaccharide agents to remove solids from an aqueous suspension.
Claims20
A method for removing solids from an aqueous suspension of solids, comprising,
- contacting an aqueous suspension of solids with a quantity of a plant polysaccharide agent for a period of time sufficient to flocculate a portion of the solids to provide a suspension comprising flocculated solids, and
- mechanically dewatering the suspension comprising flocculated solids to provide separated solids and an aqueous supernate.
A method for removing solids from an aqueous suspension of solids, comprising:
- contacting an aqueous suspension of solids having a first concentration of suspended solids with a quantity of a plant polysaccharide agent for a period of time sufficient to flocculate at least a portion of the solids to provide a suspension comprising flocculated solids, wherein the plant polysaccharide agent is an extract selected from fenugreek, cactus, okra, aloe, chia, psyllium, or tamarind extracts;
- and
- removing at least a portion of the flocculated solids from the suspension comprising flocculated solids to provide an aqueous medium having a second concentration of suspended solids, wherein the first concentration is greater than the second concentration.
A composition, comprising:
- (a) a fenugreek extract;
- and
- (b) one or more plant polysaccharide extracts,
- wherein the ratio of fenugreek extract to the one or more plant polysaccharide extracts is from about 0.5 to 2.0 based on dry weight.
