Lystek International (Lystek) and the Fairfield-Suisun Sewer
District (FFSD) have jointly been recognized for the Excellence in
Innovation and Resiliency award by the California Association of
Sanitation Agencies (CASA). This prestigious Award of Excellence
was given to Lystek and FSSD at the CASA Annual Conference on
August 1, 2024 in Monterey, California.
CASA’s statewide award program recognizes
achievements in the clean water community that promote the
utilization of renewable resources and promote environmental
sustainability as well as public health protection. The category of
Innovation and Resiliency recognizes efforts in the innovative
application of technology or the development of new technology to
the wastewater field, such as collection, treatment, wastewater and
biosolids recycling, and renewable energy production. These are
highly innovative and increase resilience and/or have a broad
application to the industry.
FSSD wastewater treatment operations produce an
effluent discharge to the San Francisco Bay which contributes
unwanted nutrients and can cause environmental stress to the
eco-systems of the Bay. While pursuing treatment plant upgrades,
FSSD partnered with Lystek to divert anaerobic digestate away from
their dewatering process and directly to the Lystek system, thereby
reducing nitrogen-rich filtrate from returning to the plant’s
influent. The result has shown reductions in the concentrations of
nitrogen in FSSD’s effluent and subsequent discharge to the
adjacent Suisun Marsh (which connects to the San Francisco Bay).
The project is titled Digestate Direct Dilution (D3) and utilizes
sustainable practices by incorporating existing assets and
digestate transfer redundancy for resiliency. The incremental
reduction of nutrient concentrations in the FSSD effluent for the
cost of this project is many times less than the expected capital
expenditures for implementation of advanced technologies and new
infrastructure.
FSSD and Lystek have been cooperating on a
Public-Private Partnership (P3) since 2016 in the management of
biosolids for diversion of residuals and organics for land
application in Northern California. "This project demonstrates the
ability of the public and private sector to work together and
realize an immediate reduction in overall nutrient content in the
plant effluent while diverting these nutrients to agriculture for
beneficial use as soil amendment land application," said
Jordan Damerel, General Manager of FSSD.
Jim Dunbar, General Manager for Lystek, added,
“By working in close partnership with FSSD and Lystek, both parties
have seen the benefits in achieving our missions of providing an
environmental service to the public and the surrounding nature we
are charged to protect."
