Summary: Reverse Osmosis (RO) is the dominant technology in desalination. An effective pre-treatment is the key to alleviate the major hurdle of RO, membrane fouling. In this study, we will develop an integrated membrane system to minimize RO membrane fouling. We will achieve this through establishing i) new practical fouling indices, and ii) advanced analytical protocol to characterize saline water to arrive at a novel pre-treatment of immersed membrane hybrid system (which couples membranes with flocculation and bio-adsorption). The operating parameters of this system will be optimized through a new control approach. This project will bring the benefits of strong international collaboration and lead to a sustainable pre-treatment technology.
