Method Of Clarification Of Waste Water For Production Of Animal Feeds
View pageUS Patent:
52040070, Apr 20, 1993
Filed:
Dec 30, 1991
Appl. No.:
7/814574
Inventors:

International Classification:
C02F 124
US Classification:

Abstract:
Method for removing suspended solids from a stream of waste water for subsequent use as an animal feed, wherein bentonite and an anionic polymer are added to the waste water which is maintained within a predetermined pH range. No metallic salts or other materials unacceptable as food additives are added to the waste water stream to facilitate flocculation of the bentonite and suspended solids. The pH range, maintained from 3. 5 to 9. 0 and optimally from 4. 0 to 5. 0, facilitates the coagulation of the suspended solids without the use of the metallic salts or other such additives. Microscopic air bubbles are used to float the flocculated bentonite and solids to the surface. In some cases the materials may be floated by gravity forces alone without the use of air bubbles. These floated materials are removed by skimmers or other top-floating solids removing apparatus commonly known in the industry and rendered into animal feed products.
