Jacopa’s Copa® Cyclone water-powered, self-cleaning storm screen is used in combined sewer overflow (CSO) systems, and is particularly suited to remote locations that are difficult to reach and / or monitor, which require additional screening to accomodate elevated flow levels.

 The Cyclone’s design eliminates the need for an external power supply or mechanical cleaning of the screen’s surface.

The Cyclone is ideal for retrofit and new CSO chambers. The unit can be directly bolted onto a chamber wall, over a circular outlet or span across the CSO chamber from weir wall to chamber wall. The standard drum unit size is 700mm long, and 500mm in diameter.

The unit is designed to be virtually maintenance free. The normal maintenance regime is to inspect the drum annually to ensure that it is clean and rotating freely. The shaft bearings are stainless steel, sealed for life and require no further maintenance.

Extensive trials have shown that screenings roll from the rotating face of the drum on up-stream and downstream water levels, maintaining a clear surface area.
