52 Feature article higher, with the flexibility to increase further following heavy rain. By comparison, under MIEX DOC resin, the plant operated at a treatment rate of 600 bed volumes over summer, sometimes decreasing to 400 bed volumes during periods of poor raw water quality. This operating mode will decrease the regeneration costs (salt consumption, waste generation and power consumption). As regeneration capacity is limited, it also improves the ability of the plant to deal with varying raw water quality into the future. CONCLUSIONS The Aireys Inlet demonstration validated the benefits of MIEX Gold resin, which can provide a significant change in treatment rate, compared to existing MIEX DOC resin. Along with other technological advances, this improves the viability of MIEX treatment as a cost-effective process for dealing with difficult-to-treat raw waters.
