The mass transfer coefficient in use so far, for the solute transport on the high-pressure side in reverse osmosis, is for the back-flow due to concentration polarisation from the wall (membrane interface) towards the centre of the high-pressure channel. The correlations for it are borrowed from stu
The effects of solute concentration in the range of 0.0013 to 1.051 molality in the feed solution and operating pressure in the range of 100 to 900 psig on solute transport parameter D A M I K ~ in reverse osmosis have been studied for a class of laboratory-made aromatic polyamide membranes and aque
## Cellulose acetate membranes undergo hydrolytic decomposition which is accelerated at very high or low pH levels. Hydrolysis results in the loss of acetvl groups leading to a sharp decline in membrane performance. Minimum hydrolvsis rates occur in the pH range of 4-6. ## Cellulose Acetate Memb
