Rotary Drum Screen

Internally fed rotary drum screen, also known as rotary drum screen, which is suitable for solid-liquid separation of industrial wastewater and domestic sewage, replacing the pre-sinker to remove suspended particles. The sewage enters the buffer tank from the inlet, and the special buffer tank makes the sewage gently and evenly distributed into the inner mesh cylinder, which discharges the retained material through the rotary force, and the filtered water is discharged through the gap of the mesh cylinder.
Due to the special water crossing section, the filter grate will never be clogged. The screen is made of stainless steel, which is highly resistant to corrosion.

1. High filtration precision of rotary drum screen and stable water quality of output water.

2. Through its own exploration and strain, it realizes automatic backwashing and can cope with unstable water quality fluctuations without manual intervention.

3. The rotary drum screen control system is responsive and precise, with dual setting function of differential pressure and time, which can flexibly adjust the backwashing differential pressure or time setting value according to different water sources and filtration precision.

4. The cleaning is efficient and thorough, and the filter can be completely restored to its initial state, so it can be used for life without replacement.

5. Water filtration equipment backwashing at the same time does not interrupt the normal water production, continuous operation, stable and reliable.

6. The backwashing time is short, and the backwashing water consumption is only 0.001-0.003% of the normal water production, saving water and electricity, saving energy.

7. Compact and reasonable structure design of rotary drum screen, small footprint, flexible and convenient installation and movement.

8. The equipment has few wearing parts, no consumables, low operation and maintenance costs, and simple operation.

9. The rotary drum screen has wide application fields and can be applied to different raw water quality and water requirements.
