Deionizer Typical Installation
Deionizers produce low conductivity water usually in the 5-100 ųs/cm range, which means the water is aggressive and
wants to dissolve any material with which it comes in contact. Drain lines and product lines must be made of corrosion
resistant materials, such as PVC, CPVC, or stainless steel.
The deionizer has an inlet, an outlet, and four drain lines. It is recommended that manual valves be installed on the inlet
and outlet of the system for servicing. The cation drain (C5) will transport waste acid, the anion drain (A6) will transport
waste caustic soda, and the backwash drains (C4 and A5) will transport low quality waste deionized water.
Water from
the cation and anion drains MUST ALWAYS be neutralized prior to sending it to the city sewage system.
This can
be governed by local plumbing codes and discharge permits. The maximum recommended height for the drain lines is
eight (8) feet above the top of the unit. When using a recirculation pump, installation of a check valve on the inlet of the
DI is required to prevent deionized water, acid or caustic from being fed into the incoming lines. The recirculation pump

NOTE: If you are going to heat the caustic drum, make sure that
it is positioned close enough to the Caustic Tank to ensure that
the caustic chemicals do not cool before reaching the tank.
