Comprehensive Guide to Ultrapure Water Equipment Process Flow

1. Reverse Osmosis Equipment + Ion Exchange Equipment

  • Raw Water Intake
    • Raw Water Tank: Stores the incoming raw water.
    • Raw Water Booster Pump: Increases water pressure for subsequent filtration.
  • Pre-Treatment Stage
    • Quartz Sand Filter: Removes large particles and suspended solids.
    • Activated Carbon Filter: Adsorbs organic compounds, chlorine, and other contaminants.
    • Scale Inhibitor Dosing System: Prevents scaling in the RO system.
    • Precision Filter: Ensures fine filtration before high-pressure pumping.
  • Primary Filtration
    • High-Pressure Pump: Delivers water to the RO system at high pressure.
    • RO Main Unit (Single or Double Stage): Removes dissolved salts and impurities.
  • Degassing and Intermediate Storage
    • CQ2 Degassing Tower: Removes dissolved gases like CO2.
    • Intermediate Water Tank: Stores water post-RO filtration.
    • Intermediate Water Pump: Transfers water to the next treatment stage.
  • Ion Exchange Stage
    • Ion Exchange Bed: Further purifies water by removing remaining ions.
    • Terminal Filter: Ensures the final filtration step before ultrapure water output.
  • Final Output
    • Ultrapure Water: The final product, ready for use in various high-purity applications.

2. Reverse Osmosis Equipment + EDI Device

Process Flow:

  1. Raw Water Intake
    • Raw Water Tank: Collects and stores incoming raw water.
    • Raw Water Booster Pump: Boosts pressure for efficient filtration.
  2. Pre-Treatment Stage
    • Quartz Sand Filter: Filters out large particles and sediments.
    • Activated Carbon Filter: Removes organic impurities and chlorine.
    • Scale Inhibitor Dosing System: Adds chemicals to prevent scale formation.
    • Precision Filter: Provides fine filtration before high-pressure treatment.
  3. Primary Filtration
    • High-Pressure Pump: Pressurizes water for the RO system.
    • RO Main Unit (Single or Double Stage): Conducts the primary filtration to remove most dissolved solids.
  4. Degassing and Intermediate Storage
    • CQ2 Degassing Tower: Eliminates dissolved gases.
    • Intermediate Water Tank: Temporarily holds water after RO treatment.
    • Intermediate Water Pump: Pumps water to the EDI system.
  5. EDI Treatment
    • EDI Device: Provides continuous deionization, producing high-purity water without the need for chemical regeneration.
  6. Final Output
    • Ultrapure Water: The final ultrapure water, suitable for sensitive applications.
