Method For Treating A Waste Stream Using Photosynthetic Microorganisms
US Patent:
6465240, Oct 15, 2002
Filed:
Dec 11, 1998
Appl. No.:
09/210153
Inventors:
Howard M. Wexler - Bristol CT 06010

International Classification:
C02F 300
US Classification:
4352625, 210600, 210602, 210603, 210610, 435243, 4352521, 4352571, 4352573, 4352574, 435822, 435946
Abstract:
A method is provided for treating a waste stream by contacting the waste stream sequentially with a consortium of prokaryotic microorganisms, preferably purple non-sulfur bacteria, followed by a the green algae Chlorella. The consortium of prokaryotic microorganisms assimilate a first portion of the wastes, and the green algae assimilate the remaining portion of the wastes to produce a substantially purified effluent stream. Isolated microorganisms made by the above method are valuable commercial products.

US Classification:
4352625, 435243, 4352521, 4352571, 4352891, 435822, 210601, 210602
Abstract:
The present invention is directed to a method for treating a waste stream by contacting the waste stream sequentially with a consortium of prokaryotic microorganisms, preferably purple non-sulfur bacteria, followed by a the green algae Chlorella. The consortium of prokaryotic microorganisms assimilate a first portion of the wastes, and the green algae assimilate the remaining portion of the wastes to produce a substantially purified effluent stream. The process of the present invention preferably includes a photobioreactor in order to increase the amount of light made available to the photosynthetic microorganisms, and result in improved uptake of waste materials from the waste stream.
