Product description

ZA-DF Series drum filter is composed by four parts: house, roller, back washing system and 

electric control system. Capacity: 20~200M3/H (or higher), use non-toxic seawater corrosion 

resistant high quality engineering plastic materials, and use 200 mesh (80 microns) stainless steel 

mesh to remove & separate suspended solids.

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.

Features

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

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

3). With auto back washing function to ensure system is working properly.

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

Product appliance

1) Suitable used for pre-solid-liquid separation processing of aquaculture raw water treatment.

2) Suitable used for pre-solid-liquid separation processing of aquaculture industrial water 

treatment.

3) 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.
