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.
