Abstract
The present invention relates to a method of manufacturing filtering aids, coagulants or clarifying agents, and odor suppressants and a using a protein-polysaccharide complex composition as a filtering aid, coagulant or clarifying agent, and odor suppressant for in the processing of fluids including gases and liquids to absorb a variety of separable components.
Claims13
A process for treating a liquid to remove undesirable impurities or components contained in the liquid comprising:
- contacting a liquid containing undesirable impurities with a clarifying or filtering effective amount of a filtering aid comprising a protein-polysaccharide complex composition comprising between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein to purify or clarify the liquid, separating the liquid and the filtering aid and recovering a purified or clarified liquid.
A method of filtering metals from fluid streams containing metals comprising the steps of:
- contacting a fluid containing a metal or a metal salt with a clarifying or filtering effective amount of a filtering aid comprising a protein-polysaccharide complex composition comprising between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein to purify or clarify the fluid,
- separating the fluid and the protein-polysaccharide complex composition and recovering a purified or clarified fluid.
A method for reducing malodors emanating from fluid containing compositions comprising:
- contacting a fluid containing composition having an eminating malodor with an odor reducing effective amount of a protein-polysaccharide complex composition comprising between about 90% to 99.5% by weight of a water-soluble polysaccharide impregnated with between about 10% to 0.5% by weight of a substantially water-insoluble protein to substantially reduce the malodors emanating from the fluid.
