PURE WATER TREATMENT SYSTEMS
What is Deionization?
Deionization is the process of removing positively and negatively charged ions (cations and anions) from water using ion exchange resins. This results in purer water with extremely low electrical conductivity.
Advantages:
High purity water production
Prevents calcification and sediment formation
Ideal for sensitive systems and devices
Does not leave chemical residue
Easy maintenance and long-lasting use
Our Deionization Systems
The deionization systems we offer as Polywets Industrial are designed to suit different needs:
🔹 Single Bed Deionization Systems: Provides basic purification using a single type of ion exchange resin.
🔹 Double Bed Deionization Systems: Contains two separate resin beds for both cation and anion removal.
🔹 Mixed Bed Deionization Systems: Combines cation and anion resins in the same bed for maximum purity.
🔹 Fully Automatic Deionization Systems: Requires minimum intervention with automatic regeneration and control mechanisms.
🔹 Custom Design Systems: Sector-specific and project-specific solutions.
How Does a Deionization System Work?
1️⃣ Pre-treatment: Sediment, chlorine and organic matter are separated from the water.
2️⃣ Ion Exchange Columns: The cation resin removes positively charged ions from the water, and the anion resin removes negatively charged ions from the water.
3️⃣ Regeneration: Saturated resins are renewed with chemical solutions.
4️⃣ Storage and Distribution: Purified water is stored and made available for use.

Deionization - Demineralization System Design Criteria It is crucial that deionization - demineralization pure water treatment devices are designed to meet the capacity and desired pure water quality, both during the design and implementation phases. The most important details of these systems include the correct selection of the necessary pretreatment to ensure efficient system operation based on the physical and chemical properties of the raw water to be used, the model and quantity of ion exchanger minerals to be used in the system, the selection of corrosion-resistant materials for the automation equipment and chemical suction sets used for backwashing, and the correct freshness and quantity of regeneration chemicals to be used during washing periods.

Things to Consider in Mixbed Systems: Mixbed systems, if not properly pretreated, can have both benefits and disadvantages due to high operating costs. To ensure the longevity of mixbed units, a pure water treatment system must be used to reduce inlet water conductivity.
