Chain and Scraper Systems
Proven, reliable, and cost-effective sludge collection technology
There are two main types of wastewater clarification; primary and secondary. Primary clarification removes solids prior to biological treatment. Secondary clarification follows the biological treatment process with the main goal of rapidly returning activated sludge.
Evoqua offers a variety of wastewater clarification technologies for primary and secondary treatment. Our Rim-Flo® circular clarifiers introduce feed at the periphery of tankage to increase treatment capacity and collect sludge with the our Tow-Bro® hydraulic sludge removal system. The Envirex® Chain & Scraper system from Evoqua includes high-strength non-metallic chain and durable flights to scrape sludge along the floor and skim floating solids.
Designed for virtually any size or configuration, including modular units for small & intermediate-sized applications
Provides maximum sludge concentrations or floating solids removal, regardless of treatment plant size or application
Increase performance, reduce maintenance & extend equipment life
