Radial Flow Separators

Radial Flow Separators / Settlers

The Radial Flow Separator / Settler (RFS) is a pre-filtration device for particle removal from fish system effluent flows. The RFS is also very effective in removing settleable solids such as sand and grit from fish farm supply flows. This simple, energy neutral, proven device is in use on fish farms in the United States, Canada and Norway.

Solids Removal – A Comparison of a Swirl Separator and a Radial-Flow Settler

This is an whitepaper written on the subject of solids removal in a coldwater recirculating system, comparing the efficiency of swirl separators vs. radial-flow settlers. The conclusion was that radial-flow settlers were found to provide approximately twice the TSS removal efficiency of swirl separators of identical size and surface-loading rate. Also, the use of a radial-flow settler vs. a swirl separator provided considerably reduced solids loading on the microscreen drum filter, which would be expected to reduce its backwash requirements. The whitepaper was written jointly by John Davidson and Steven T. Summerfelt.
