Rotary Drum Filter for Shrimp Aquaculture

The Juntai Rotary Drum Filter works mainly on the principle of physical filtration. In the tilapia aquaculture system, aquaculture water containing fish feces, bait residues, algae and other impurities is pumped into the drum of the microfilter. The surface of the drum is covered with a fine filter mesh, and the pore size of the mesh can be selected according to the size of the impurity particles that need to be filtered, usually between tens of microns and hundreds of microns. When the breeding water enters the drum, under the action of water pressure, the water passes through the filter mesh, while the impurities are intercepted on the inner surface of the filter mesh.

 
When the water containing small suspended matter enters into the drum, the small suspended matter is retained by the stainless steel screen mesh, and the water without suspended matter enters into the artesian tank after filtration.

When the drum of suspended solids accumulated to a certain amount, will cause the water permeability of the screen decreased, resulting in a rise in the water level in the roller Jane, when the water level rises to a set high water level; level automatic control components work, at this time, the backwash pump and the roller Jane reducer at the same time automatically open the work of the backwash pump high-pressure water through the microfilter backwash components of the rotating drum screen high-pressure cleaning, clogging in the roller on the Jane filter screen Suspended matter on the screen of the roller simple screen will flow into the dirt collection tank and then be discharged through the sewage pipe under the high pressure water washing.

When the screen is cleaned, the water permeability of the drum screen. Rise, the water level in the drum falls, when the water level barriers to the set low water level, the backwash pump and roller simple reducer will automatically stop working, the microfilter and enter a new round of work cycle.
