Circular Clarifiers

Circular clarification separation processes are widely used to treat contaminants for removal from water and wastewater. Some systems settle solids out of the liquid stream by gravity; others use flotation methods to float the solids to the top to be skimmed away.

Clarifiers at an Industrial Textile Plant

For removing particles and reducing total suspended solids (TSS) to low levels, Siemens offers almost every type of water and wastewater clarification technology, including circular and chain and scraper type clarifiers, separators and flotation devices, as well as a complete range of skimmers, decanters and other ancillary equipment Our clarifiers are available in virtually any size and configuration, including modular units for small and intermediate-sized applications. These efficient, compact units are designed to minimize installed costs.

Case Study: Rim-Flo® Clarifier at Neuse River WWTP

The Raleigh, NC treatment plant is a conventional activated sludge plant with both diffused air and jet aeration. Although their circular clarifiers were operating very well, the plant wanted to determine the performance characteristics of one of the large-diameter Rim-Flo® Clarifiers under normal and high flow conditions, with particular emphasis on the overall hydraulic characteristics.
