Understanding the transformation kinetics of iron and copper species is critical to maintaining Australia's water resources since i) iron transformations are key to generation and transport of acid in Australia's coastal environment; ii) growth of toxic algae are stimulated by dissolution of iron-rich sediments with subsequent release of nutrients phosphorus and iron, and iii) algal toxicity is related to iron and copper nutrition and interplay of these metals with oxygen. Additionally, global cycles of carbon, phosphorus and nitrogen are influenced by iron and copper interactions with light and oxygen. Improved understanding of these processes should lead to an awareness of how to prevent these problems and, if they occur, approaches to their mitigation.Read moreRead less

This project is aimed at studying pre-treatment options for composite fouling which is the main type of fouling present in RO units by using both model feed systems and actual field water. The project outcomes are to understand and develop pre-treatment strategies and to use those to develop a hybrid pre-treatment technology. This project will significantly impact water production in general and its outcomes will have far-reaching implications in treatment of water both within Australia and globally.Read moreRead less
The Boron Rejection by RO Membranes in presence of Calcium Carbonate and Magnesium Hydroxide. Water scarcity in various parts of the world demands the use of available saline waters for production of potable water. Reverse Osmosis membranes have been used as a means of achieving this objective. Fouling is a major impediment in operation of reverse osmosis units.

Water scarcity in various parts of the world demands the use of available saline waters for production of potable water. Reverse Osmosis membranes have been used as a means of achieving this objective. Fouling is a major impediment in operation of reverse osmosis units. The project aims to study boron removal by RO under high pH which increases the boron rejection but at the same time exacerbates composite fouling by calcium carbonate and magnesium hydroxide. Optimum pH for boron rejection will be determined and propensity of calcium carbonate and magnesium hydroxide at that pH range will be evaluated.Read moreRead less
