Characteristics of the Filter: 1. Capable of filtering precision liquids with high solid content and producing dry residue. 2. One-time filtration of particles larger than 0.5 μm. 3. Rapid gas backflushing for residue discharge and simultaneous filter tube regeneration. 4. Rigid microporous PE and PA filter tubes with excellent chemical resistance ensure long service life and significantly reduce operating costs. 5. Sealed filtration for safe operation, no odor leakage, improved production environment, and compact footprint. 6. Specially designed sealing rings enable quick opening and closing of the large-diameter pneumatic residue discharge bottom cover. 7. Easily integrated into automated control systems. 8. External insulation jackets and internal anti-corrosion coatings can be added based on process requirements. Successful Applications: 1. Filtration and washing of ultrafine products (e.g., catalysts, molecular sieves, ultrafine magnetic powders). 2. Precision filtration and washing of biological fermentation broths. 3. Precision refiltration to remove precipitated proteins from fermented filtrates after initial filtration. 4. Precision filtration of powdered activated carbon. 5. Precision filtration of sugar solutions. 6. Primary or secondary brine precision filtration in chlor-alkali and soda ash production. 7. Precision filtration of caustic soda to remove crystalline salts; precision filtration of sodium bicarbonate solutions to improve clarity. 8. Precision liquid desulfurization filtration in chemical fiber, coking, and petrochemical production. 9. Precision filtration of heavy metal wastewater (chromium, copper, nickel, zinc, lead, cadmium). 10. Precision filtration for recovering chemical products from industrial wastewater (e.g., carbon black, soda ash, sodium bicarbonate). 11. Precision filtration of wastewater containing fluorine, sulfur, phosphorus, and latex paint wastewater. 12. Precision filtration of dust scrubber wastewater for recycling and reuse. 13. Product recovery filtration following vacuum drum, plate and frame, belt, or cartridge filters. 14. Filtration for oilfield water injection.
