How to reduce fouling in reverse osmosis membranes?

Fouling in reverse osmosis membranes membranes is a critical problem that compromises efficiency, increases energy consumption and raises operating costs in water treatment systemsmineral deposits require higher pressures, reduce the flow of treated water and force frequent chemical cleanings. Recently, the control of this fouling has evolved from a simple operational practice to an essential […]
