Conventional external pressure UF membrane module cannot adapt high-concentration activated sludge biochemical tank environment, fiber breakage and rapid fouling often occur. LEFILIER LF-MBR immersed UF membrane is dedicated sewage Ultrafiltration membrane in the catalog, special flexible anti-sludge PVDF fiber can work stably under long-term aeration scouring. This frame-type Ultrafiltration membrane module completes solid-liquid separation of sewage sludge, permeate water can directly enter all types of RO membrane filter for advanced reuse treatment. All sewage treatment membrane products are placed in Water Filter Element page, gas phase filter elements at gas filter element.
Submerged MBR Separation Principle Of LF-MBR UF Membrane Module
LF-MBR UF membrane frame is fully immersed in biochemical sewage tank. Negative pressure suction acts on the inner cavity of Ultrafiltration membrane hollow fiber, sludge flocs, bacteria and macromolecular organic matter are trapped on the outer fiber surface; clean clear water penetrates into the fiber and flows to the rear Reverse Osmosis membrane element. Continuous aeration at the bottom of the tank scours the surface of Ultrafiltration membrane module to reduce sludge accumulation, extend the maintenance cycle of UF membrane.
Core Performance Parameters
Membrane Material: Flexible sludge-resistant PVDF for UF membrane module
Nominal Interception: 0.01μm for sewage Ultrafiltration membrane
Single Frame Membrane Area: 10/15/20㎡ different specifications of UF membrane
Max Safe Transmembrane Pressure: 0.05MPa negative pressure
