Dagyee IRD9-2500 SUS304 SUS316 Wedge Wire Pharmaceutical Wastewater Static Screen

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.

Applicable Scenarios of External Rotating Drum Screen

• Industrial and municipal applications

• Primary and secondary treatment stage

• Protection of membrane plants

• Replacement for primary settlement tank

• Load reduction in the biological treatment system

• through reduction of COD / BOD/ AFS

• Screening in the inlet to power plants

• Treatment of cooling water circuits

• Brewery wastewater

• River and sea outfall

• Surface and river water screening

External Rotary Drum Screen Benefits

• Internal water inlet, high removal rate;
• Adjustable drum speed, low energy consumption;
• Backwashing mode can be set to adopt the most water saving mode;
• Structure of the equipment is made of stainless steel and corrosion resistant.

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.
