Method of Waste Treatment & Algae Recovery – a 1977 Patent<\/strong><\/p>\n

Abstract<\/p>\n

A method of waste treatment and algae recovery involves making available in a first pond open to light and air a first body of waste water such as sewage containing algae, the algae growing on the contained nutrients. The first body is retained under natural culture conditions for a predetermined detention period, usually several days, and is then transferred to a second pond as a second body open to light and air. To the second body some normal algal nutrients are added and more particularly the body is continuously agitated at a moderate rate to maintain the growing algae in suspension. Preferably, to the second body and with the nutrients, there is added an amount of lime insufficient to cause coagulation of the algae. After a predetermined detention time of several days in the second, mixing pond the mixed material is transferred to a third pond. The third pond is shielded from the light and is dark. The third pond is unagitated and is quiet. The algae therein readily separate…
