Recently, reverse osmosis technology is becoming a promising method for treating wastewater or as a desalination method for seawater. However, the bottleneck of this technology is membrane fouling. A lot of experimental effort has been made to investigate the effect of operating conditions on the rate and mechanism of fouling, but the nature of the feed water is also known to be one of the important parameters that affect membrane fouling. Colloidal fouling in RO system is the main concern as it can seriously degrade the membrane performances. Thus, it is essential to have a method that can predict the fouling potential of feed water by colloids.
The current study mainly focuses on developing better fouling indices to predict particulate fouling in RO systems such that the operating condition of system can be varied according to the fouling characteristics. This project also includes the use of non-invasive techniques to examine cake structure on membrane surface and the modelling of cake enhanced osmotic pressure (CEOP) of a RO system.
