✦ Synopsis

The effect of a variable power input on a reverse osmosis desalination system has been studied. Membranes were subjected to a continuous sinusoidal f3ow velocity change at a constant system pressure of 600 psi. Feed was a brackish water solution of sodium chloride and tap water.

For the test period, it was found that constant variation in the feed velocity had no effect on the membrane performance.

In fact, the product flux and salinity curves were similar to those obtained under steady state conditions. lhTRODUCTlON The Brace Research Institute has developed a wind turbine for power and irrigation purposes in isolated arid areas (I, 2). Chilcott (I) has shown that this prototype windmiii can produce efficient power for water pumping and desalination. For this reason, studies have been undertaken into the feasibility of adapting conventional desalination plants to rhe variable power output f;om the windmill.
