The source water for the deionizer can be ground water or tap water.

Depending on the quantity of high grade water needed, a first-stage pre-conditioner deionizer, such as a Culligan or Continental System, or equivalent, may be needed to provide feed water to the high-purity system.

If large quantities of high quality deionized water are needed, it may be advisable to supply the laboratory grade deionizer with preconditioned water from a Culligan , Continental , or equivalent mixed-bed water treatment system.
