16. emonstrates membrane productivity 15 very sensitive to changes in feedwater temperature As water temperature increases water flux increases almost linearly due primarily to the higher diffusion rate of water through the membrane Increased feedwater temperature also results in lower salt rejection or higher salt passage This is due to a higher diffusion rate for salt through the membrane The ability of a membrane to tolerate elevated temperatures increases operating latitude and is also important during Cleaning operations because it permits use of stronger faster cleaning processes NOTE EFFECT OF RECOVERY As shown in Figure 1 reverse osmosis occurs when the natural osmotic flow between a dilute solution and a concentrated solution is reversed through application of feedwater pressure If percentage recovery is increased and feedwater pressure remains constant the salts in the residual feed become more concentrated and the natural osmotic pressure will increase until it is as high as the applied feed pressure This can negate the driving effect of feed pressure slowing or halting the reverse osmosis process and causing permeate flux and salt rejection to decrease and even stop please see Figure The maximum percent recovery possible in any RO system usually depends not on a limiting osmotic pressure but on the concentration of salts present in the feedwater and their tendency to precipitate on the membr
