Notes:
A new class of polyacrylic membranes has been tested under reverse osmosis conditions on dilute (1%-4%) salt solutions. Fluxes up to 0.2 gal-mil/ft2-day at greater than 98% rejection have been achieved. The effect of membrane composition on product flux and salt rejection is discussed. Increased fluxes at even higher rejection should be possible by proper selection of the type and concentration of hydrophilic, hydrophobic, and crosslinking monomers. It is concluded that improved membranes should have as high as possible a concentration of hydrophilic groups, distributed randomly through a lightly crosslinked, rubbery polymer matrix.
