LF-BWFR Anti-Fouling RO Membrane Filter For High Turbidity Factory Raw Water

Factories with high-turbidity raw water often face frequent biological scaling of ordinary RO membrane. Conventional Reverse Osmosis membrane element easily accumulates algae and organic dirt, requiring monthly chemical cleaning and increasing production cost. LEFILIER LF-BWFR anti-fouling RO membrane is special modified RO membrane element for high-pollution raw water, the hydrophilic anti-adhesion coating of this RO membrane filter reduces organic adsorption by over 60%, salt rejection still reaches 99.6% under long-term high turbidity running, far superior to standard Reverse Osmosis membrane. As heavy-duty industrial desalination core, LF-BWFR Reverse Osmosis membrane element must be matched with large-flow UF membrane module to intercept suspended solids, protect the surface of RO membrane filter. Our factory has independent membrane R&D laboratory, all anti-fouling RO membrane pass 1000-hour fouling aging test, all water filtration consumables at Water Filter Element, oil gas purification filters at gas filter element.

Anti-Fouling Working Principle Of LF-BWFR RO Membrane Element

High turbidity brackish water flows tangentially over LF-BWFR RO membrane. The special smooth hydrophilic coating on this Reverse Osmosis membrane repels organic pollutants and calcium salt crystals, dirt cannot form dense biofilm on RO membrane filter surface. Salt ions, heavy metals and suspended particles are continuously washed away by concentrated water flow, stable permeate water flux of Reverse Osmosis membrane element can be maintained for long cycles, cutting cleaning labor and chemical agent cost greatly.

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: 1.55MPa (225psi)

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

• Matching Pre-Treatment: Large flux UF membrane module

Each LF-BWFR Reverse Osmosis membrane element completes anti-scaling aging test, fit industrial wide-bore pressure vessels matched with High Flow Filter.
