Abstract

Sewage effluent and sewage sludge were used as culture media for Chlorella pyrenoidosa in the laboratory. It was discovered that the growth rates, chlorophyll contents, protein contents and dry weights of C. pyrenoidosa cultivated in the effluent, 2% sludge extract and the enriched medium, Bristol's solution, were similar. It was also noted that the effluent and sludge extract contained tolerable levels of heavy metal for the growth of algae. The outdoor mass production of algae with sewage effluent has been conducted all over the world with success. It is suggested to use sludge extracts for the same purpose in the near future.
