Original Brine Sediment Removal Bag Filter Element

Product Details

The original brine sediment removal bag filter element is specially designed for raw brine pretreatment and coarse filtration. Made of high-strength PP needle punched felt or PTFE membrane, it features excellent dirt holding capacity and chemical stability. It effectively intercepts solid particles such as sediment, aquatic weeds and large particle slags in raw brine, protecting the stable operation of subsequent precision filtration equipment and process systems.

Product Features

3D Structure: PP needle punched felt forms a deep gradient filtration layer, capturing impurities on the surface and holding particles inside fibers to greatly increase dirt holding capacity and service life.

High Flow & Low Pressure Drop: Optimized porosity ensures high liquid flow while intercepting large particles, reducing energy consumption.

Acid and Alkali Resistance: Chemically inert material adapts to high-salinity and corrosive liquids like raw brine.

Anti-shedding Treatment: Inner surface treated by singeing or calendaring prevents fiber shedding under high-speed fluid flow, avoiding secondary pollution.

Reliable Sealing: Tight fit with filter support basket via metal or plastic ring, eliminating bypass leakage and ensuring filtration accuracy.
