This Priority Research Theme plays a significant role in maximising the efficiency of the preferred desalting technology. The Centre funded research that would lead to an improved understanding of the relationship between pre-treatment and treatment, and how novel pre-treatment technologies and improvements can reduce fouling and/or scaling of the coupled treatment process.
These were the primary research areas:
- Preheating using waste heat or renewable energy and the use of lower-pressure membranes;
- Optimal use of chemicals;
- Specific issues for pre-treatment in rural and remote areas relating to seasonal and location variability in feedwater composition; and
- Characterisation of groundwater and seawater sources and mapping those to best fit desalination technologies.
Across the five Priority Research Themes, investment in pre-treatment research represented 23% of the Centre’s total research investment, with 27 of the 50 projects addressing one or more of these primary areas.
