ABSTRACT:
An improved method for promoting algae growth in a sewage medium is disclosed. A high density algae culture can be obtained in a sewage water treatment process by placing algae in pure water separated by a dialysis membrane from sewage water wherein osmotic interaction occurs across the membrane. In a preferred embodiment algae is placed in pure water in dialysis tubing and the tubing is suspended in the presence of light in sewage water for osmotic interaction therewith.
