 Organic waste floating on the surface through this circulation from the capillary wave is slowly drawn past the mouth of the skimmer where it is pulled in due to the laminar flow and surface tension over the skimmer weir.In a well-designed pool, circulation caused by the disturbed returned water aids in removing organic waste from the pool surface, directing it to be trapped inside the consecutive dilution system for easy disposal.Many return jets are equipped with a swivel nozzle.
