All the benefits of deionized water without the ridiculous costs.
No capital investment, maintenance, labor or chemical costs, or wastewater treatment problems.
-
Features
Our DI systems feature a charge ion exchange resin. This reduces mineral ions from water, improves water quality and reduces scale buildup, improving commercial and industrial operations.
-
Benefits
Provides high-quality water for specialized applications without capital investment. Regeneration or exchange provided by Culligan of Central Texas. This system reduces on-site labor and regenerant chemical handling. We offer a configuration of weal-base or strong-base resin tanks.
-
Advantages of PEDI Systems
PEDI systems reduce both positively and negatively charged ions from water by means of ion exchange resins. We also offer portable exchange softening (PES) systems, which deliver a constant supply of soft water to small and large operations, without a capital investment.
-
Automatic Deionization
Automatic DI is a proven, cost-effective component in an integrated Culligan system for improved commercial and industrial quality. Its corrosion-resistant construction features a pumped regenerant system for consistent dosing. The system automatically rinses until your desired effluent quality is reached.

DEIONIZED WATER TREATMENT in CENTRAL TEXAS
What is deionized water?
Deionized (DI) water is water that has had dissolved mineral ions (such as calcium, sodium, iron, copper, and chloride) removed through ion exchange resins. The process of deionization removes ions from water using ion exchange resins. It produces highly purified water by attracting and removing positively and negatively charged ions, making it useful in industries like electronics and pharmaceuticals.
What are the types of high purity water?
- Deionized (DI) Water – Removes ionized salts and charged particles. Commonly used in labs, electronics manufacturing, and processes where mineral deposits can disrupt operations.
- De-mineralized Water – Similar to DI, with most minerals and salts removed through ion exchange, carbon filtering, or microfiltration. Used in applications requiring high purity.
- High Purity Water – Essential in semiconductor and pharmaceutical manufacturing, where impurities can affect processes or product quality. Achieved through multi-stage treatment like RO, UV, and DI.
- Lab & Medical Grade – Meets strict purity standards for research and medical use. Involves advanced filtration, RO, DI, UV treatments, and sub-micron filtering to remove bacteria and pyrogens.
How is DI different from reverse osmosis (RO) or softened water?
- Softened water removes hardness minerals only.
- RO removes a wide spectrum of impurities but may leave trace ions.
- DI produces the highest resistivity/purity levels, ideal for lab, medical, and industrial use.
How long do resins last?
Resin life depends on incoming water quality and usage volume. Culligan technicians monitor and exchange tanks as needed to ensure continuous water purity.
What are the operating costs?
Running a DI water system requires more than just the equipment itself. Costs include the upfront system investment, replacement of consumables such as resins and filters, energy use, water consumption, and waste disposal. You’ll also need to account for maintenance, repairs, labor, and the handling of regeneration byproducts. Careful cost management and system optimization help ensure consistent, high-quality water production while keeping operating expenses under control.
What are the maintenance requirements for a DI water system?
Maintaining a DI water system involves regular monitoring of water quality, periodic regeneration or replacement of ion exchange resins, pre-filtration to remove contaminants, system flushing, sanitization to prevent bacterial growth, and regular maintenance checks of system components.
What purity levels can I expect?
Culligan DI systems can achieve effluent water resistivity up to 18 megohm-cm, depending on system design.
What are the Specifications of DI Models & Tanks?
How do I know if a DI system is right for my business?
If your processes require water that is free of dissolved minerals or salts, a DI system is often the best solution. Industries like healthcare, labs, electronics, and food processing rely on DI because even small amounts of minerals can cause equipment damage, product defects, or compliance issues. A Culligan water expert can test your water and recommend whether DI is the right fit.
What happens if my water demand grows over time?
Culligan DI systems are designed to scale. You can start with a single tank or small setup, and we can add additional tanks or reconfigure your system as your operation expands. This flexibility means you won’t outgrow your water treatment solution.
Is DI water safe for drinking?
No. DI water is not intended for drinking or cooking because the ion exchange process strips out essential minerals. It is strictly used for industrial, commercial, and laboratory applications where high-purity water is required.
How quickly can I get DI service?
Culligan provides local service and rapid tank exchange throughout the San Marcos area. In most cases, exchanges are scheduled proactively so your business never experiences downtime. Emergency service is also available when needed.
Do DI tanks help with environmental compliance?
Yes. Culligan’s portable exchange DI systems eliminate on-site chemical handling and wastewater disposal. Spent resins are regenerated at a licensed Culligan facility, with metals safely recovered and recycled — helping businesses meet environmental regulations while reducing liability.
What types of businesses benefit most from DI water?
Any operation that requires consistent, mineral-free water can benefit from DI tanks. Common examples include labs, hospitals, semiconductor manufacturers, food and beverage processors, automotive plants, and power generation facilities. Even small businesses like dental offices and research labs often rely on DI water for reliable results and compliance.
