These recommendations are based on element size and quality of feed water being treated. The concentrations of the dissolved and suspended solids in the boundary layer control the performance of the membrane.

to reduce the contaminant to a safe level. The quality of the incoming water, or feed water, is crucial here. For example, if the water supply contains nitrate at 40 mg/L, an RO membrane with 85 percent rejection would reject 40 x 0.85 = 34 mg/L nitrate, leaving 6 mg/L in the treated water. However, if the water supply contains 80 mg/L nitrate, an
