Clarification and separation technologies remove suspended solids from wastewater, providing a clarified liquid effluent for downstream treatment processes. 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. Rim-Flo® circular clarifiers introduce feed at the periphery of the tank to increase treatment capacity and collect sludge with the Tow-Bro® hydraulic sludge removal system. Envirex® chain and scraper systems use high-strength non-metallic chain and durable flights to scrape sludge along the floor and skim floating solids. CoMag® ballasted clarification systems provide rapid settling for increased capacity and enhanced nutrient removal. Folded-Flow® Dissolved Air Flotation Separators introduces air or gas into recirculated effluent to float and remove suspended solids.
Read a recent case study, Turn-Key Solution Eliminates Chain and Scraper Downtime in Grass Valley, to learn how Evoqua quickly installed new clarification equipment to prevent downtime, reduce maintenance and increase the efficiency of solids removal.
