Many South Australian groundwater sources contain elevated iron concentrations. The presence of iron in water does not pose a risk to human health, but it can lead to brown discolouration and possible staining of fixtures and washing. IRPs are a simplified version of conventional water treatment plants, where chlorine is added to oxidise the iron to an insoluble form that precipitates naturally, forming small floc. The iron floc is removed from the water by filtration through sand media. SA Water is currently engaged in a program to upgrade many iron removal plants by installing facilities to capture and reprocess backwash water. This will reduce the amount of groundwater extracted and minimise environmental impact.
