Dagyee IRD9-1800 Factory Seawater Rotating Drum Screen Separators Ion-Exchange Pretreatment

The internal feed rotary screen operates very little. Influent water enters through the inlet and flows into the headbox. The headbox is filled with water and the inlet overflows onto the weir and contacts the sides of the rotating cylinder screen. When the incoming water hits the rotating screen, the solids are trapped in the cylinder and the liquid enters the process through the screen or continues to be processed. A splitter on the cylinder moves the solid along the length of the screen for discharge. The device is equipped with spray bars head to clean the screen.

How Does External Rotary Drum Screen Work

The discharge to be treated enters through the shaped wall located outside the screen body,evenly distributed by the overflow channel, and overflows on the rotary drum filter. Solids will remain on the rotary drum surface as the drum rotates, and the effluent entering through the screen will perform self cleaning function when it passes through the bottom of the rotary drum again. After passing through the external scraper, the solid is detached from the rotary drum.
