REVERSE OSMOSIS GENERAL PRETREATMENT
These are standard pieces of equipment necessary to help your reverse osmosis operate
correctly. Individual circumstances, configurations and the type of system will determine if all the
above equipment is necessary, if more is necessary or if less can be used.
1.
Automatic backwashing sediment filter
This filter should be used in areas with higher sediment content. Dirty water can
clog the pre-filter of the R.O. causing an incoming pressure drop.
2
Automatic backwashing carbon filter
The reverse osmosis unit CANNOT tolerate chlorine. It is very important to properly
maintain the carbon unit. Doing so maintains the life expectancy of your membranes.
3.
Twin alternating water softener
Fouling and scaling on the membrane is one of the main reasons a water softener is
recommended before an R.O. It is always best to use a twin alternating unit in order
to ensure continuous soft water.
