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.

Since 2010 the City of Los Angeles’ Hyperion Treatment Plant started running its own FOG Digestion Pilot Project. The project’s objective is to achieve a 10 to 20% increase in gas production by adding processed grease trap waste to the plant’s anaerobic digesters. With over two years of experience to date, it’s time to check in with the project engineers. Mr. Ronald Palacios, PE is an Environmental Engineer for the City of Los Angeles’ Hyperion Treatment Plant in Playa Del Rey, California.

Decentralized water recycling facilities can reduce the capital cost for water conveyance infrastructure and provide a reliable and sustainable source of local water supply. The City of Anaheim, CA (City) provides potable water to approximately 350,000 people within a 50 square mile area, which results in a demand of approximately 75,000 acrefeet per year (AFY). In order to augment the existing water supply and to demonstrate sustainability features to the public, the City decided to build a demonstration‐scale water recycling facility (WRF) next to the City Hall. The WRF has a treatment capacity of 115,000 gpd and consists of MBR and ozone treatment processes to produce disinfected tertiary effluent that meets the Title 22 requirements of the California Department of Public Health (CDPH).

LABS September Dinner & Presentation
The Santa Susana Field Laboratory (SSFL), located in western San Fernando valley was a premier test facility involved in rocket engine testing and nuclear energy research. The legacy of these activities resulted in environmental contamination of soil and groundwater. While the technical challenges of this site were being assessed, public concerns regarding site contamination lead to cleanup that is vastly more stringent than well-established state and federal law. This presentation provides a case study on how Boeing integrated the technical challenges of cleanup with community concerns to demonstrate to local stakeholders that Santa Susana could be – and would be – a public benefit if comprehensively and responsibly remediated using standards that are both protective and responsible in returning the area back to open space parkland.
