Industrial Water Filtration – The perfect protection for RO.

Reverse Osmosis (RO) is a widely used method of water purification used in both industrial and commercial applications.

The main function of RO is to remove a large range of unwanted molecules and ions from water so this water can be used as required, for example for the paper making process in a paper mill or as potable water for consumption in a desalination plant.

A very brief description of the RO process is to force a liquid of high concentration through a semi-permeable membrane at a higher pressure than Osmotic pressure.  The semi-permeable membrane will only allow water through but stops soluble molecules such as salt (desalination.)

As the semi-permeable membrane (RO membrane) is of such as fine grade, in the majority of circumstance the RO membrane requires a good level of protection to remove solids and larger particulate (down to approx. 5 micron) before it reaches the RO membrane.  Without this level of protection in place the RO membrane will become loaded in a very short period of time.  Cleaning and in some more severe circumstance replacing the membranes and become extremely costly.

This is where Industrial water filtration plays a large part in providing efficient and reliable pre-filtration protection to the RO system.  Industrial water filtration provides a protective barrier filtering out water at any required flow rate down to less than 1 micron.  By using Industrial water filtration this way means that the RO system can operate effectively without risk of damage.  For example, in many industrial applications water is taken from alternative sources such as rivers, oceans and boreholes.  The quality of this water can be very variable and can contain high levels of suspended solids (silt, sand.) or biological material and wildlife (algae, mussels, eels.)  These need to be removed or obstructed before they can enter to RO system.

Industrial water filtration will do this efficiently at any given flow rate and filtration degree.  If you would like to know more about this subject please contact us.
