LF-BW Standard Brackish Water RO Membrane For Factory & Municipal Pure Water Plant

Factory water treatment operators often encounter unstable desalination rate of cheap RO membrane, after several months of operation, salt rejection drops sharply and cleaning cost surges. LEFILTER LF-BW standard Reverse Osmosis membrane is mass-produced flagship RO membrane element for light brackish water, the stable modified polyamide layer ensures long-term consistent performance of this RO membrane filter. Before raw water enters LF-BW Reverse Osmosis membrane element, matched UF membrane module pre-treatment can effectively intercept colloids and algae, slow down fouling speed of RO membrane. LF-BW series are core standard models in our pure water product catalog, all water filtration consumables are displayed at Water Filter Element, oil & gas coalescer cartridge and natural gas filter can be viewed via gas filter element.

Working Principle Of LF-BW RO Membrane Element

Municipal tap water or light brackish water flows tangentially over LF-BW RO membrane surface under standard operating pressure. Dense polyamide film of this Reverse Osmosis membrane only allows water molecules to penetrate into central permeate pipe, salt ions, suspended solids and microorganisms are fully intercepted and discharged with concentrated water. The smooth hydrophilic surface of RO membrane filter reduces organic adhesion, extend the chemical cleaning cycle compared with ordinary low-cost Reverse Osmosis membrane element.

FAQ About LF-BW RO Membrane

Q1 What raw water fits LF-BW RO membrane filter?
A1 Tap water and light brackish water with TDS below 2000ppm, not for seawater Reverse Osmosis membrane element.

Q2 Must match UF membrane module before RO system?
A2 Yes, Ultrafiltration membrane intercept colloids to protect RO membrane from fast fouling.

Q3 What cleaning agent can use on this Reverse Osmosis membrane?
A3 Standard weak acid & weak alkali special cleaning liquid for industrial maintenance.

Q4 Can LF-BW replace imported standard RO membrane element directly?
A4 Same outer dimension, direct installation into common pressure vessels.
