Enhance Filtration Efficiency 110m³/h ultrapure Water treatment plant for Silicon Wafer Cleaning with edi module
I. Overview
Ultra-pure water is a core component in silicon wafer cleaning for achieving efficient, low-defect photovoltaic cell production. Its application directly determines the cleanliness of the silicon wafer surface, minority carrier lifetime, and ultimately, cell efficiency.
Industry rule of thumb: For every 10-fold increase in the purity of ultra-pure water used in silicon wafer cleaning, cell efficiency gains of up to 0.15% can be achieved—“Photovoltaic competitiveness begins with the first drop of ultra-pure water.”
II. Process
Wafer Loading → SC1 Cleaning → Ultrapure Water Rinsing → HF Acid Cleaning → Ultrapure Water Rinsing → SC2 Cleaning → Ultrapure Water Final Rinsing → Drying

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 )
