Abstract |
This report is an interpretive analysis of formal and informal developments at the Ninth International Conference on Water Pollution Research held in Stockholm, Sweden, on June 12-14, 1978, and has been prepared for the U.S. Environmental Protection Agency by the U.S.A. National Committee for Representation of the United States to the International Association on Water Pollution Research. Information of particular significance concerning developments in international water pollution research included: In the developed countries the emphasis is changing from energy intensive physical-chemical processes back to biological systems for removal of both organic matter and nutrients from wastewaters; a chemical-biological system for the removal of both organic matter and nutrients from wastewaters requires a design using mechanistic principles and parameters which integrate both the chemical and biological processes rather than treating them separately. |
