Ultra-pure water equipment is a specialized device that employs multi-stage precision treatment processes to remove nearly all impurities from water, including ions, organic compounds, colloids, microorganisms, particles, etc., thereby producing ultra-pure water with extremely high resistivity (typically ≥18 MΩ·cm at 25°C). Its core objective is to meet the requirements of industries and fields that are extremely sensitive to water quality, such as semiconductors, pharmaceuticals, precision electronics, and high-end scientific research.

III. Process Flow Diagram
Standard Configuration:
Raw Water → Raw Water Tank → Booster Pump → Flocculant/Reducer Dosing → Activated Carbon Filter → Ultrafiltration (UF) → Scale Inhibitor Dosing → Security Filter → 1st Stage High-Pressure Pump → 1st Stage RO → pH Adjustment → Intermediate Tank → 2nd Stage High-Pressure Pump → 2nd Stage RO → Purified Water Tank → EDI Booster Pump → UV Sterilizer → Cartridge Filter → EDI System → Ultra-Pure Water Tank → Transfer Pump → TOC Removal Unit → Polishing Resin → Final Filter → Point of Use
Process Highlights:
Multi-Stage Pretreatment: Removes particles, organics, and chlorine to protect RO membranes.
Dual RO System: Achieves salt rejection rate for consistent high-purity water.
EDI Technology: Continuous electro-deionization eliminates the need for chemical regeneration.
Polishing Resin: Final purification stage for ultralow TOC and ionic contaminants.
