External Feed Drum Filter Screen for Wastewater

External Feed Drum Filter Screen for Wastewater External Feed rotary Drum Filter screen is used for solid/water separation which usually consists of more dense particles that need to be removed from the effluent. The effluent enters the inside of the rotating drum through the feed inlet and then passes over the distribution weir on the drum surface. The particles and water separate as the drum rotates with the solids staying on the screen and passing down the length of the drum helped by internal flights or a continuous scroll. The external feed rotary drum screen is also equipped with a special flushing device. External feed drum filter screen brushes away the impurities that stick to the surface of the screen and removes even the smallest amount of impurities. The screen cylinder is rinsed twice internally to achieve optimum grating cleaning. At the same time, an internal rinsing device is provided to rinse away the dirt adhering to the mesh holes.
