The externally loaded TanFlow drum screen is notable for its robust and straightforward design, plus a small footprint that also allows it to be used in tight spaces. It is employed everywhere where solids need to be separated from larger liquid flows, irrespective of whether this is in industrial or municipal applications. Even oily and fatty media can be separated.

Operating principle

The process or waste water is fed through a feed chamber onto the drum screen surface. The liquid first flows through the drum from the outside in. This deposits solids larger than the selected slot size on the surface. These are then transported by the steady rotation of the drum to a scraper, where the solids are removed carefully. After separation, the cleaned liquid flows through the drum again, from the inside out, and then flows off through a drain connector.
