Evoqua is the pioneer of non-metallic chain components, now considered the standard in the industry. The Envirex® Chain and Scraper sludge collection system provides maximum sludge concentrations and floating solid removal. The system is comprised of light-weight components, which makes installation easy and simplifies maintenance. Flights mounted on two parallel strands of non-metallic chain scrape the settled solids along the tank floor to sludge hoppers. On the return run the flights can skim the surface and concentrate the floating material at a scum removal device.
For high load and grit applications, the Envirex Heavy-Duty Sludge Collector System provides dependable, long lasting performance. High strength components including stainless steel chain and sprockets provide longer life and reduced wear to meet the toughest applications.
