Beyond Nitrification – Benefits of Higher Solids Retention Time Operation

By Dr. Michael Stenstrom, Ph.D, P.E.

 The activated sludge process is the most common method of secondary municipal wastewater treatment; solids retention time (SRT) is the key control parameter for this process. Typically, operating at long SRT is considered only for nitrification, but there are additional benefits of high SRT operation. The presentation will present experimental and literature evidence to demonstrate three major additional benefits of long SRT operation: increased oxygen transfer efficiency; improved biomass particle size distribution, which results in more efficient clarification with fewer effluent particles and suspended solids; and enhanced removal of many emerging contaminants such as pharmaceuticals, personal care products, and endocrine disrupting compounds. This presentation will present the results from several treatment plants demonstrating these benefits. A long-term survey of three treatment plants concludes that operating at higher SRT is not as energy intensive as commonly assumed.
