I.Overview
Deionized water equipment plays a crucial role in photovoltaic cell production, serving as the “lifeblood system” of photovoltaic cell production. Its core value lies in providing high-purity water quality to ensure that key processes such as silicon wafer processing, cleaning, and cell manufacturing are not contaminated by impurities. It is the key to purity assurance, cost reduction and efficiency improvement, and sustainable development.
II.Main Process
Raw Water→Pretreatment→UF (Ultrafiltration)→Two - stage RO (Reverse Osmosis)→CEDI (Continuous Electrodeionization)→ Polishing Mixed Bed→Terminal Ultrafiltration → PV Production Line (Photovoltaic Production Line)
III.Core Application Stages & Water Quality Requirements
| Stage | Function | Water Quality Requirements | |||||
| Silicon Material Cleaning | Remove metal ions (e.g., Fe³⁺, Ca²⁺) and particles from silicon surface | Resistivity ≥ 15 MΩ·cm；Boron ions ≤ 5 ppt | |||||
| Silicon Ingot Cutting Fluid Preparation | Dilute cutting fluid to avoid surface damage | Conductivity < 0.1 μS/cm (≈ Resistivity > 10 MΩ·cm)；TOC < 10 ppb | |||||
| Battery Chip Surface Cleaning | Remove chemical residues, metal contaminants & particles after etching | Particle size ≤ 0.02 μm；Microorganisms < 0.001 CFU/mL | |||||
IV.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
