Internal Rotary Micro Filter

Workflow

Inlet water filtration: sewage enters axially from the inside of the drum, flows out radially through the gap of the mesh cylinder, and the impurities are retained in the inner wall of the mesh cylinder;

Dregs removal and cleaning: the rotation of the drum brings the retained materials to the top, and then flushed into the dregs removal tank through the high-pressure backwash water to realize continuous automatic dregs removal. Filtration media: adopt stainless steel hard grid or micron-level filter plate, with high mechanical strength and deformation resistance.

Core structure and features

Structural design

drum screen: built-in slag guide screw, combined with backwash spray system to prevent clogging;

drive device: frequency conversion speed control, suitable for different working conditions; Frame material: stainless steel or anti-corrosion treatment, to adapt to the highly corrosive environment.

Performance Advantages

Filtration: suspended solids ≥ 80%, fiber recovery rate of up to 98%;

Automated operation: continuous water intake, slag discharge, no need for manned operation;

Low Maintenance Low maintenance cost: backwashing system reduces the frequency of manual cleaning, stable operation;

Small footprint: compact structure suitable for space-constrained sewage treatment scenarios.

 Application areas

 Industrial wastewater treatment

paper mills: recovery of pulp fiber (recovery rate ≥ 98%), purification of white water recycling;

textile printing and dyeing / chemical plants: clean up suspended solids and chemical fiber residues.

Municipal and public facilities

Sewage treatment plant: as a fine grille to intercept hair, plastics and other impurities;

Water plant: raw water filtration, cleaning algae, plankton ( Algae removal rate of 40-70%).

Other scenes: aquatic processing wastewater treatment, circulating cooling water purification.

Technical parameters and selection

 Key parameters

Filtration precision: pore size 0.2mm~15μm;

Processing capacity: daily processing capacity of a single machine can reach 36,000 cubic meters;

Power range: 0.75kW~3.5kW. Power range: 0.75kW~3kW (depending on the model).

Suggestions for selection:

Select the type of filter media (orifice plate/wedge mesh) according to the concentration of suspended solids and the size of particles;

Wastewater with high fiber content is preferred to be equipped with enhanced backwash system.

Operation specification

Check the status of flushing pipeline valves before starting to ensure that the backwash function is normal;

Regularly clean the slag discharge tank to avoid secondary pollution.

Maintenance requirements

quarterly check the tightness of the transmission chain, adjust to a good operating condition;

mesh broken or clogged need to stop to replace/clean.
