LF‑BW‑8040‑FR Anti‑Fouling RO Membrane Element For High‑Turbidity Factory Raw‑Water

Factories with high‑turbidity raw‑water often suffer frequent biological scaling of ordinary RO membrane. Conventional Reverse Osmosis membrane element accumulates algae and organic contaminants rapidly and requires monthly chemical‑cleaning which increases production cost. Our Oil Filtration Machine supporting LF‑BW‑8040‑FR modified anti‑fouling RO membrane filter adopts special hydrophilic anti‑adhesion coating. Organic adsorption can be reduced more than 60%, salt‑rejection still maintains 99.6%‑99.7% under long‑time polluted raw‑water running. This heavy‑duty Reverse Osmosis membrane must cooperate with large‑flux UF membrane module for suspended‑solid interception. Check full water‑treatment catalog at Water Filter Element. Security filtration selects High Flow Filter Cartridge.

Anti‑Fouling Working Principle Of LF‑BW‑8040‑FR RO Membrane Element

High‑turbidity brackish‑water flows tangentially on LF‑BW‑8040‑FR RO membrane surface. Special smooth hydrophilic coating of this Reverse Osmosis membrane repels organics and calcium‑salt crystal deposition. Dirt cannot form compact bio‑film on RO membrane filter surface. Salt‑ions, heavy‑metals and suspended particles are continuously washed away by concentrated‑water flow. Reverse Osmosis membrane element maintains stable permeate‑water flux for long cycles and greatly cuts chemical‑agent and labor cost for cleaning work.

Core Technical Parameters

• Membrane Material: Anti‑fouling hydrophilic polyamide for RO membrane filter

• Stable Salt Rejection of Reverse Osmosis membrane:99.6%‑99.7%

• Standard Test Pressure of RO membrane element:1.55 MPa (225psi)

• Special Design:34mil wide flow‑channel for RO membrane

• Matching Pre‑Treatment: Large‑flux UF membrane module

Each LF‑BW‑8040‑FR Reverse Osmosis membrane element completes anti‑scaling aging test before delivery; fits industrial wide‑bore pressure vessels with High Flow Filter Cartridge.
