Industrial Water Purifier - China

Applicable Standards

Industrial water purifier systems adhere to global purity and safety benchmarks, including: ASTM D1193 (Specifications for Reagent Water)

USP <643> (Total Organic Carbon in Pharmaceutical Waters)

ISO 3696 (Water for Analytical Laboratory Use)

SEMI F57 (Ultrapure Water Specifications for Semiconductor Manufacturing)

GB/T 6682 (China’s National Standard for Laboratory Water)

These standards define purity levels (e.g., resistivity ≥18.2 MΩ·cm, TOC <10 ppb) for specific industries.

Working Principle

The system employs a multi-stage purification process: Pre-treatment: Sediment/carbon filters remove large particles, chlorine, and organic matter.

Reverse Osmosis (RO): Semi-permeable membranes reject 95–99% of dissolved salts and ions.

Electrodeionization (EDI): Ion-exchange resins and electric fields further polish water to ultrapure levels.

UV Sterilization: 185/254 nm wavelengths destroy bacteria and degrade TOC.

Ultrafiltration: 0.22μm filters ensure particle-free output.

Test Principle & Validation

Pure water systems undergo rigorous testing: Resistivity/Conductivity: Real-time monitoring to verify ion removal (18.2 MΩ·cm = 0.055 μS/cm).

Total Organic Carbon (TOC): Oxidation-based analyzers detect organic contaminants (<10 ppb for semiconductor use).

Microbial Testing: Membrane filtration or ATP bioluminescence assays confirm sterility (<1 CFU/mL).

Endotoxin Validation: LAL (Limulus Amebocyte Lysate) tests ensure <0.03 EU/mL for pharmaceutical applications.

Applications include: Pharmaceuticals: Sterile water for injection (WFI) and cleaning validation.

Electronics: Rinsing wafers in semiconductor fabrication.

Power Plants: Boiler feedwater to prevent scaling.

Laboratories: HPLC solvents and analytical reagent preparation.

Industrial pure water machines are indispensable for industries demanding zero-tolerance contamination, offering scalable, efficient, and validated solutions for critical processes.
