  • Performance comparison of rotating disk ultrafiltration membrane module, a high shear device with cross–flow module

    Apart from plenty of advantages, the main disadvantage of ultrafiltration is rapid flux decay due to concentration polarisation and membrane fouling. The purpose of this work is to overcome this problem employing shear enhanced membrane filtration technique. To accomplish this, two different membrane modules were used; one was a standard cross–flow membrane module and the other one was the ...

  • An experimental study on the effect of spacer on concentration polarization in a long channel reverse osmosis membrane cell

    This study was to experimentally investigate the performance and organic fouling behaviour in a 1-m long RO membrane channel with or without spacer for desalting. It was found that local permeate flux distributed heterogeneously along the long membrane channel without a spacer inserted due to exponential growth of concentration polarization, which also resulted in decreasing salt rejection and ...
