Located in Evesham, New Jersey the Elmwood Wastewater Treatment Plant was prompted to upgrade its filtration process to address three aging traveling bridge sand filters that had reached the end of their useful life.
The municipality contracted with the engineering firm Alaimo Engineers to evaluate tertiary filtration options. It was determined that the replacement of three existing traveling bridge filters that had reached the end of their useful life with two disc filtration units would be a cost-effective solution for addressing future tertiary filtration requirements.
Evoqua’s Forty-X Disc Filter Armor series combines the technology of outside-in and inside-out filtration into a single PLC controlled unit. Influent water flows through the pre-screen (outside-in) into the disc filter panels (inside-out). This innovative combination of two filtration technologies into one unit provides an effective and robust option for those challenging filtration applications.
The Elmwood Wastewater Treatment Plant upgraded their existing traveling bridge sand filters with disc filtration increasing capacity and performance.The two Forty-X™ Disc Filter Armor series units at the Elmwood Wastewater Treatment Plant were started up in October 2021 and have a peak flow of 3 MGD while maintaining a consistent effluent quality less than 5 mg/L TSS.
