Fairfield-Suisun Sewer District Reduces Plant Polymer Usage With Polyblend® DP Dry Polymer Preparation System Demo Trailer

<p>Located between San Francisco and Sacramento in Solano County, California, the Fairfield-Suisun Sewer District (FSSD) services more than 135,000 residential, commercial and industrial customers over 41 square miles. Built in 1974 and updated most recently in 2010, the state-of-the-art facility consists of a tertiary waste treatment plant averaging 13.7 million gallons per day (MGD) with a capacity rated at 23.7 MGD. Sustainability is a priority at Fairfield, and energ-yefficient practices and technology are used throughout the facility, including a gas engine that operates on methane produced in the digester; the engine heat warms both the sludge for digestion and the maintenance building. They also have four 50 kilowatt (kW) wind turbines on site and approximately 30% of the consumed power is produced by an on-site solar array.</p>
