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 of Epoxy Coating to withstand acid/alkali regeneration cycles.

Product Beschrijving

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:

  • 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.

Voordeel één

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.

Voordeel TWEE

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.
