Reverse Osmosis is a function of temperature, pressure and dissolved solids.  In order for the water to pass through the membrane it requires greater pressure on the high side.  Warmer water helps to reduce the back pressure while high dissolved solids increases the back pressure.  Therefore in order to get maximum production all three factors must be taken into consideration.  Over the years membranes have increased in there production capacity.  Two types of membranes are generally used due to the aggresiveness of chlorine.  CTA membranes are used with high levels of chlorine but are not as productive as TFC membranes.  TFC membranes are sometimes used on less cholorinated water with a carbon filter to remove the aggressive chlorine prior to the membrane.  Chlorine will actually destroy a TFC membrane but the TFC membrane will give greater production/rejection.

Reverse Osmosis will remove 60 – 98% of the Inorganics depending on the contaminant.  By testing the water you can determine what if any additional filteration you would require to obtain the type of water you need.  Reverse Osmosis generally is economical, more productive and takes less to maintain than Deionization or Distillation. It has become the most accepted method for home use.
