TonkaFlo reverse osmosis pump is designed to apply the pressures needed to push liquids through the semi-permeable membranes. With a high pressure pump, feed water is continuously pumped at elevated pressure to the membrane system. Within the membrane system water is allowed to pass through the membrane but not the impurity. In the reverse osmosis process, the water that passes through the membrane is commonly referred to as permeate, or product water, the water that remains behind the membrane along with the dissolved and suspended solids is referred to as the concentrate, brine or reject water. RO membrane elements are designed to be operated at a specified pump pressure to create the proper product flow and rejection. Cellulosic membrane elements generally require twice the pump pressure compared to thin-film membranes. Operating the RO at a lower than suggested pump pressure will result in reduced product flow.
