| Abstract |
A two-stage pond system was operated as a process for polishing secondary sewage effluent. The shallow first stage was an oxidation pond in which a heavy growth of algae was permitted to develop. In the second stage a population of Daphnia pulex consumed the algae. Detention times were about 10 days in each stage. Chemical and biological monitoring were carried out over a year's period to determine feasibility of using the process to produce recreational-grade water and reduce algae growth potential.
