Rotary Drum Screen
Product introduction
Rotary drum screen is widely used in urban sewage, industrial wastewater, food processing industry, paper industry, and other sewage treatment projects. The equipment salvage and remove the scum, staple fiber, and suspended solids at the intake of the water source, and squeeze and dehydrate them before discharging. Suitable for high-precision treatment, suitable for small grid gaps, and shallow channel depth of wastewater treatment occasions.


Low water head loss, high separation efficiency, and large processing capacity.
All stainless steel manufacturing, low maintenance, long service life.
Equipped with a washing device, with a self-cleaning function.
Set multiple functions in one system, compact structure.


The equipment integrates four functions intercepting pollution, removing slag, spiral lifting, and pressing dehydration. The equipment is installed in the canal at 35° with the horizontal plane, and the sewage flows into the drum from the port of the drum. The water flows out through the grid gap on the side of the drum, and the grid intercepts the suspended objects and floating objects in the water in the drum, and the drum rotates at a certain speed. The top of the drum is provided with a nylon brush and a washing water nozzle to remove the grid slag and lift the output through the spiral. The grid slag is dehydrated and pressed before being discharged into the container or subsequent transport device, and the whole process is clean and odorless.
