Reverse Osmosis

Reverse Osmosis (RO) is a membrane process that acts as a molecular filter to remove more than 99% of all dissolved minerals. Water passes through the membrane while the dissolved and particulate matter is left behind. As pressure is applied to the concentrated solution, the flow is reversed and water is passed through the membrane from the concentrated side to the dilute side. RO can be effectively used for the reduction of Total Dissolved Solids in groundwater, surface water and sea water applications.

The success of RO technology can be attributed largely to the economics of its operation and to its simplicity. Compared to other salt removal technologies, it is relatively inexpensive to purchase and to operate. It requires neither an energy intensive phase change such as distillation nor a large volume of strongly acidic and caustic chemicals, such as those required for ion-exchange systems.

RO design considerations

To allow us to size your RO plant accurately both from a technical and an economical point of view we require basic data such as:

Complete chemical and physical analysis of raw water
Average temperature of raw water
The amount of water you expect to use per 24 hour period
Your peak water demand
Use and destination of the purified water
