Wedge Screen Tube for Wastewater Treatment  

The  wedge wire screen tube (rotary drum screen) is renowned as a fine screen for pretreatmentin wastewater treatment plants. It widely used in meat processors, food processors, tanneries, textile mills, petrochemical plants, and recyclers, the users rely on it for product recovery and wastewater treatment.

How it works

An externally-fed type, the influent is directed under a baffle, then upward and over the length of the drum. The natural action of wastewater flow through the screen creates a powerful backwash which results in a continuously clean surface. Solids are caught on the outside of the screen surface and are removed by a tensioned doctor blade

If it's an internally-fed rotary type with wedge wire tube(cylindrical) screen. Influent enters through the inlet and flows into a headbox. The headbox fills and the influent flow over the weirs and touch two sides of the rotating drum screen. As the influent hits the turning screen, the solids are caught inside the drum and the liquid passes through the screen into the process or on for further treatment.
