Drum Filters  remove solid waste from water using a fine mesh screen. The fine mesh screen traps waste particles, while allowing water to flow through. Sensors tell a connected control box when it’s time to rotate and clean the filter. 
During the cleaning cycle, the control box rotates the drum and activates the high pressure spray bar. The spray bar removes the trapped waste from the fine mesh screen and directs it into the stainless steel waste tray.
