Polyamide reverse osmosis composite membrane is a kind of seawater desalination membrane. It consists of three layers: a non-woven physical support layer, a polysulfone ultrafiltration membrane int...
How is reverse osmosis membrane fouling caused? How to solve it?
Membrane fouling is a significant problem which has a negative impact on its performance. It reduces both rejection and flow rate, r...
After using the water purifier for a period of time, contaminants in the RO membrane will accumulate. At this time, the reverse osmosis membrane needs to be cleaned.
The cleaning frequency of the ...
