A few days ago, Kennedy/Jenks Consultants from the United States was honored with the annual Engineering Achievement Award by the California Water Environment Association (CWEA) for pioneering a groundbreaking wastewater treatment method. This innovative filtration technique employs a large-diameter filter medium during the backwash phase, significantly enhancing filtration efficiency and reducing operational and maintenance costs.
According to recent reports, a wastewater treatment plant in South Bay is currently conducting large-scale testing of this new method, and early results have surpassed expectations. Traditionally, solid removal from wastewater involves a dual-media granular filter using anthracite and sand. However, the test used a single-layer anthracite medium with a diameter 2.5 times larger than conventional materials. The facility now processes around 20 million gallons of wastewater daily, ensuring a steady water supply for areas like Menlo Park, Sequoia City, and Portola Valley.
Experts involved in the project believe that if the test results continue to show positive outcomes, the adoption of this single-media filtration system across the industry could lead to substantial cost savings. This advancement not only improves efficiency but also offers a more sustainable and economically viable solution for wastewater treatment facilities nationwide.
