Stainless Steel Mixed Bed Deionizer – Ion Exchange Polisher Vessel (With Sight Glasses)
Stark Mixed Bed Deionizer (STK1 Series) is a specialized ion exchange vessel for ultrapure water polishing. Featuring a high-tower design with dual sight glasses for resin monitoring, it offers optional Rubber Lining or Epoxy Coating to withstand acid/alkali regeneration cycles.
Product Description
The Final Step to Ultrapurity (18 MΩ·cm).
While Reverse Osmosis removes 98% of salts, the Stark STK1 Mixed Bed Polisher is required to remove the remaining trace ions. By mixing cation and anion resins in a single tall column, this vessel produces ultrapure water suitable for semiconductor, pharmaceutical, and high-pressure boiler applications.
Optimized Regeneration Design:
1. Corrosion Resistance: Since resin regeneration requires strong Acid (HCl) and Alkali (NaOH), we offer internal Rubber Lining (3-5mm) or Epoxy Coating to protect the stainless steel shell.
2. Visual Monitoring: Equipped with standard Sight Glasses, allowing operators to clearly see the resin separation interface during the backwash and regeneration process.
Internals & Regeneration Specs:
The efficiency of a mixed bed depends on its internal distributor system (middle collector). For detailed drawings of the acid/alkali injection nozzles and resin filling ratios, please reference the technical data at our manufacturing division:

Applicable Industry
- Semiconductor & Electronics:
Produces Ultrapure Water (UPW) essential for wafer cleaning. The polisher ensures resistivity reaches the theoretical limit of 18.2 MΩ·cm. - Power Plant Boiler Feed:
Removes silica and trace ions to prevent scale on turbine blades in high-pressure steam systems. - Laboratory & Pharmaceutical:
Provides Grade 1 reagent water for critical analysis and injectable drug formulation.
Advantage One
Precision Regeneration Control (Sight Glass)
Regenerating a mixed bed requires separating the Anion and Cation resins into two distinct layers. The STK1 series features strategically placed Sight Glasses.These windows allow operators to visually confirm the interface level between the resins during backwashing, preventing cross-contamination and ensuring successful regeneration.Advantage TWO
Corrosion-Resistant Lining Options
To withstand the harsh Hydrochloric Acid and Sodium Hydroxide used during regeneration, we offer an optional Internal Rubber Lining.This lining creates a robust chemical barrier, protecting the stainless steel vessel from corrosion and significantly extending the service life of the equipment in acidic/alkaline environments.Related Products

FAQ
Q1: How long does the reverse osmosis system last?
The lifespan of a reverse osmosis system depends on water quality and maintenance. Typically, the membrane lasts 2–3 years, while the system itself can last over 10 years with proper care.
Q2: Can the system be customized based on different water conditions?
Yes, all our systems are fully customizable. We analyze your water report and application needs before providing tailored solutions.
Q3: What standards does STARK equipment comply with?
Our products comply with CE, ISO 9001, and can be designed to meet specific regional regulations or industry standards upon request.
Q4: What is the delivery time for STARK RO systems?
Standard systems are shipped within 7–15 days. For customized orders, lead time may extend to 20–25 days depending on complexity.
Q5: Do you provide technical support or installation guidance?
Yes. We provide full technical documentation, remote guidance via video, and can dispatch engineers internationally upon request.
