THE PHENOMENON OF CALCIUM SULPHATE DEPOSITS ON REVERSE OSMOSIS MEMBRANES WAS STUDIED EXPERIMENTALLY. A MATHEMATICAL MODEL WAS PROPOSED AND SOLVED, WHICH CAN PREDICT THE PRODUCT FLOW RATE, AS WELL AS THE TOTAL DEPOSITS ON THE MEMBRANE AS A FUNCTION OF TIME. THE MODEL IS BASED ON THE FOLLOWING ASSUMPTIONS: 1. THE RATE OF DEPOSITION IS PROPORTIONAL TO THE DEVIATIONS FROM EQUILIBRIUM CONDITIONS, 2. THE EXTENT OF MEMBRANE PERMEABILITY DECREASE IS PROPORTIONAL TO THE TOTAL SALT MASS DEPOSITED. SIMPLE PREDICTING EQUATIONS WERE PROPOSED FOR THE PARAMETERSOF THE MODEL AS A FUNCTION OF TEMPERATURE AND PRESSURE. THE ABILITY OF THE MODEL TO DESCRIBE THE PHENOMENON AND THE ACCURACY OF ITS PREDICTIONS ARE SATISFACTORY, AS SHOWN BY THE RELEVANT EXPERIMENT...
