Generally KDF is used in a purification system as a pre-filter, before another, finer stage of filtration, for example, reverse osmosis, deionisation and ion exchange systems.

The units have a built in prefilter to prolong the life of the reverse osmosis membrane and nuclear deionisation, organic adsorption, ultra-filtration and ultra-violet sterilisation and also available depending on the purity of water required.

Its industrial water and wastewater treatment plants (e.g. desalination, demineralisation, deionisation) are utilised to produce pure or ultra-pure water for process use and treat hazardous wastewater for safe discharge at power plants, oil refineries, gas processing plants, petrochemical plants, manufacturing plants, breweries and other process plants.

Helium provides about as short deionization time as hydrogen, but can withstand lower voltage, so it is used much less often.

The PureFlow uses a deionization process to create a 60 liter batch of dialysate.

Milli-Q water purifiers use resin filters and deionization to purify the water.

"Reverse osmosis, UV, chlorine, deionization - it all tastes good to me."

Some aquarists filter or purify their water through deionization or reverse osmosis prior to using it.

However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin.
