Deionized Tank Exchanges provide deionized water onsite at a customer’s facility. Tanks are connected to a customer’s potable water supply and produce deionized water with flow rates from a
few gallons per minute, up to several hundred gallons per minute.

Deionized water, also known as demineralized water (DI water, DIW or de-ionized water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.
Deionized Water Tank Exchange Service is also called “Portable Exchange Deionization” or “Service Deionization”. This process flows your process water through tanks at your facility containing deionization resin, which we exchange for fresh tanks when needed. After exchanging, your tanks are regenerated at a WaterProfessionals Regeneration Facility for reuse in the future. This way, you have minimal up-front investment by eliminating complicated plumbing and installation, and you’re only paying for the high-purity water that you need.
For over 42 years, WaterProfessionals has engineered custom deionization solutions that scale from critical laboratory benchtop units to large-capacity industrial trailers. Unlike single-brand providers, we utilize a vendor-agnostic approach to source the best equipment for your specific application, ensuring compliance with rigorous ASTM, CLSI, and CAP purity standards where required.
For facilities seeking to minimize operational risk, our Service Deionization (SDI) platform delivers flows from 0.5 to 500 GPM via portable exchange tanks, effectively eliminating the need for on-site chemicals, hazardous waste treatment, and OSHA compliance training.
Whether you require a permanent installation or emergency response within 24 hours, our application engineers design systems that balance capital constraints with operational performance, offering flexible purchase, lease, or pay-per-gallon rental options.
