Magnetic Ion Exchange (MIEX)

Magnetic Ion Exchange (MIEX)

At our Mount Pleasant and Middle River Water Filtration Plants, we use Magnetic Ion Exchange (MIEX®) to treat the water. Mount Pleasant was the first plant in the world to use this revolutionary process.

MIEX® – a specialised ion exchange resin which contains unique magnetic properties was developed after many years of research and teamwork by SA Water, Orica Watercare and the CSIRO Division of Molecular Science.

MIEX® resin is added to the raw water to remove dissolved organic carbon (DOC) prior to employing conventional water treatment processes. DOC is found in all natural water sources and is the result of the decomposition of

What does MIEX® do?

The MIEX® resin works like a magnet, attracting dissolved organic carbon (DOC) in the water. DOC is the main cause of colour in water, and it can affect both the taste and smell of drinking water.

Using this process has the side benefit of reducing the chlorine dose needed to disinfect the water.

Why is MIEX® innovative?

The resin can be regenerated and recycled through the plant again and again. It also reduces cost because it removes the need for large resin stocks. It's a continuous and flexible process, one that can adjust to wide variations in the quality of source water.

Magnetic Ion Exchange benefits include:

  • Cost-effective removal of dissolved organic carbon
  • Significant reductions in the creation of disinfection by-products
  • Lower volumes of chemicals needed (both coagulant and chlorine)
  • Lower volumes of sludge production
  • Reduction in water colour
