Automatic Drum Filter

Our Drum filters are a mechanical and self-cleaning filters specially designed for high performance in systems where it is essential to prevent particles from fragmentation. The water is filtered through the periphery of the drum. Backwash of the filter is only required according the loading of particles.

2.  Working principle

When the water containing particles of suspended solids enter into the drum, suspended solids are stainless steel filter retention, filtered water which does not contain suspended solids enter into water tank. When the suspended solids accumulate to a certain amount inside roller, it will reduce the filter permeable capacity, so increase the drum water level, when the water level reaches to the fixed high level, the water level auto-control system starts working, back washing pump and roller motor start working at the same time, and use high pressure water to wash running mesh. The suspended solids be washed into the dirt collection tank and then exhausted from outfall by high pressure water. When the mesh is clean, it will improve the filter permeable capacity and reduce the drum water level, when the water level reaches to the fixed low level, back washing pump and roller motor stop working, and drum filter will start the new working recycle.

3.   Features

1). Use with high quality plastic material and SS316L mesh, corrosion resistance and durable.

2). Use special made SS316L mesh with small size aperture, low resistance and high discharge capacity.

3). Auto back-wash function ensures that system is working properly.

4). Low power consumption, high efficiency, easy operation and maintenance.

Applications

Applications

  • Suitable used for pre-solid-liquid separation processing of aquaculture raw water treatment.
  • Commercial swimming pools
  • Suitable used for pre-solid-liquid separation processing of aquaculture industrial water treatment.
  • Widely used in various lines which required pre-solid-liquid separation. Such as urban sewage water, paper, textile, printing and dyeing, chemical and sewage etc.
