Rotary Drum Screen for Wastewater Treatment

What is a rotary drum screen filter? A rotary drum filter, also known as a rotary drum screen or rotary sifter, is equipment commonly used in municipal and industrial water treatment processes. It is typically employed as the second pre-treatment process in wastewater treatment plants, following screening. The rotary drum filter is usually positioned upstream of the system, at the outlet of the pumping station responsible for collecting wastewater. In addition to its primary function of fine particle separation, the rotary drum filter can also effectively remove mechanically coarse debris such as trash rack debris (RAG), thick sands, and grease. This prevents these wastes from mixing with mud and interfering with downstream processes. The Rotating Drum Screen is an internally fed rotary drum screen designed for heavy water/wastewater pretreatment applications, including draining, mud thickening, and treating sandy or industrial wastewater. It is especially well-suited for use in membrane bioreactor (MBR) treatment plants. This rotary drum screen offers an outstanding solution for the removal of small particles. Its exceptional removal efficiency perfectly caters to the requirements of Membrane Biological Reactor (MBR) designs. How does a rotary drum screen work? The rotary drum screen operates by sorting various fine and coarse materials. The water initially enters a container and is then poured onto a circular drum screen. The raw water, along with any debris present, passes through the drum screen due to gravity, allowing for sifting. As the drum rotates slowly, the debris becomes trapped on the surface of the trommel screen. […]
