Abstract

A set of studies was carried out to see whether it would be feasible to implement technologies to enhance evaporation ponds as a form of brine disposal at regional desalination plants. The technologies in question were Wind Assisted Intensified Vaporization (WAIV) and a Fluidized Bed Pellet Reactor complimenting a reverse osmosis system. Aided by the Water Corporation, the studies were conducted to see whether the technologies were feasible to introduce to three water treatment plant sites using evaporation ponds in Western Australia. The study was conducted by the combination of modelling with the advice from the Water Corporation and other water treatment companies. The studies revealed that the technologies were not feasible due to costs and the conditions at these sites. Therefore, further modelling was done to find in what circumstances these technologies would be feasible. Findings indicated that increasing brine flows, reducing costs or adhering to certain water qualities could create scenarios where these technologies would be feasible. The research project should provide valuable information for future construction or expansion of regional desalination plants in Western Australia.
