As core purification component of industrial pure water systems, water filter element RO membrane series, also named Reverse Osmosis membrane, removes salt ions, colloids, bacteria and heavy metal ions from raw water efficiently. Each standard RO membrane element adopts composite polyamide membrane layer, achieving stable high desalination rate under long continuous operation. Before entering the RO membrane module, raw water needs to be pre-filtered by high flow filter to intercept large suspended particles and extend the service life of the Reverse Osmosis membrane.
Working Principle of RO Membrane Element
Under certain operating pressure, raw water flows along the surface of the RO membrane. Pure water molecules pass through the dense membrane layer and enter the central permeate tube to form clean product water. Salt, organic matter, microorganisms and impurities cannot pass through the Reverse Osmosis membrane and flow out along the concentrated water pipeline. The spiral-wound structure of the RO membrane element enlarges filtration area per unit volume, improving water production efficiency and reducing floor space of the whole water treatment equipment.

FAQ About Industrial RO Membrane
Q1 What raw water pretreatment is needed before RO membrane?
A1 Equip high flow filter, UF membrane and activated carbon filter to remove large particles and colloids to protect Reverse Osmosis membrane.
Q2 What is the standard desalination rate of RO membrane element?
A2 Standard brackish water RO membrane reaches over 99.2% salt rejection rate, seawater type customized separately.
Q3 What cleaning solution can be used for fouled RO membrane?
A3 Weak acid and weak alkaline cleaning agent are allowed for periodic online cleaning of the RO membrane.
Q4 Can RO membrane work at high temperature?
A4 Long-term stable working temperature shall not exceed 45℃, high temperature will damage the Reverse Osmosis membrane layer.
