WHAT IS THE MEMBRANE PROCESS?
In water treatment, membranes are used to filter pollutants from water depending on factors like size or charge.
PROS OF MEMBRANE PROCESS?
- Less space is needed than in conventional treatment schemes.
- Simple operation.
- Easy disinfection without chemicals.
- Flexible. Depending on the impurities that need to be eliminated and the desired water quality by the end user, many types of membranes can be used to treat water.
As an example：
- To generate clean drinking water from brackish groundwater, nanofiltration (membrane softening) can be used.
- To remove dissolved solids, membrane filtration (microfiltration and ultrafiltration) is commonly used.
NOTE: The membrane has to be replaced regularly to maintain its performance and effectiveness in water treatment.
