Demineralization (DM) Water Treatment Plants: Achieving Ultra-Pure Water

Our Demineralization (DM) Water Treatment Plants deliver the highest quality ultra-pure water, ideal for critical applications demanding exceptionally low levels of dissolved solids and ionic impurities. These plants are meticulously engineered and constructed to meet the stringent requirements of diverse industries, ensuring reliable performance and consistent water purity.

Applications:

• Pharmaceutical Industry: Meeting the USP (United States Pharmacopeia) and other stringent regulatory standards for injectable drugs, pharmaceutical manufacturing, and cleaning validation.
• Power Generation: Protecting high-pressure boilers and turbines from scaling and corrosion, maximizing efficiency and lifespan.
• Semiconductor Manufacturing: Essential for silicon wafer cleaning and etching processes, ensuring flawless chip production.
• Electronics Industry: Maintaining the integrity of delicate electronic components during manufacturing and testing.
• Chemical Processing: Providing ultra-pure water for specific reactions and processes requiring the absence of ionic contaminants.
• Laboratory Applications: Supporting research and analytical testing where the highest purity water is paramount.

Technology:

Our DM plants utilize a robust combination of technologies to remove virtually all dissolved minerals and impurities:

• Pre-Treatment: This crucial initial stage often incorporates a combination of processes like:
  • Coagulation and Flocculation: Removes suspended solids and colloids.
  • Sedimentation: Allows heavier particles to settle out.
  • Filtration: Removes remaining particulate matter using sand, multimedia, or cartridge filters.
  • Activated Carbon Filtration: Removes organic matter and chlorine. This is especially important to protect downstream ion exchange resins.
• Ion Exchange: The core of the DM process, using strong acid cation (SAC) and strong base anion (SBA) resins to remove virtually all dissolved ions like calcium, magnesium, sodium, chloride, sulfate, and silica. This produces water with exceptionally low conductivity.
• Polishing (Optional): For applications demanding the highest purity, additional polishing stages can be included, such as:
  • Mixed Bed Polishing: A final mixed bed ion exchange unit containing both cation and anion resins removes any remaining ions, resulting in water with ultra-low conductivity.
  • Ultrafiltration (UF) or Reverse Osmosis (RO): Further reduce dissolved organic matter and colloidal silica.
  • Ultraviolet (UV) Disinfection: Eliminates any remaining microorganisms.

Key Features & Benefits:

• Customizable Designs: Tailored to specific water quality requirements and flow rates.
• Modular Design: Allows for easy expansion and upgrades to meet future needs.
• Automated Control Systems: Ensures consistent water quality and minimized operator intervention.
• Real-time Monitoring: Provides continuous data on water quality parameters, enabling proactive maintenance and troubleshooting.
• Efficient Operation: Optimized for minimal energy consumption and water wastage.
• Robust Construction: Utilizing high-quality materials and components for long-term durability and reliability.
• Comprehensive After-Sales Support: Including installation, training, maintenance, and spare parts.
