Introduction：Water Recycling Solution for Photovoltaic Material Production

The photovoltaic materials industry is undergoing a green revolution, with manufacturers seeking sustainable wastewater treatment for solar panel production. A leading Chinese materials company specializing in fuel cell proton exchange membranes has implemented an innovative 4,000 m³/day water reuse system, combining advanced membrane technologies to achieve zero liquid discharge (ZLD). This photovoltaic wastewater treatment project demonstrates how manufacturers can significantly reduce freshwater consumption while maintaining production quality.

Project Overview

Challenges in Photovoltaic Material Wastewater

The production process generates wastewater containing:

• Moderate COD levels (≤40 ppm)

• High fluoride concentrations (≤80 ppm)

• Elevated TDS (≤5,000 mg/L)

• Chloride and hardness compounds

Traditional treatment methods struggle to achieve the ultra-pure water standards required for photovoltaic material manufacturing.

Advanced Water Reuse Treatment Process

The EPC water treatment system features a multi-stage approach:

1. Pretreatment & Ammonia Stripping - Removes volatile compounds

2. Bio-MBR System - Provides efficient organic removal

3. Fluoride & Hardness Removal - Chemical precipitation + filtration

4. Dual-Stage RO System - Ensures TDS ≤220 mg/L for production reuse

Key System Advantages

• Modular ultrafiltration (UF) + reverse osmosis (RO) for maximum salt rejection

• Automated resin polishing for consistent water quality

• Compact footprint ideal for industrial facilities

• Operating cost: ~$2/m³ - cheaper than freshwater procurement

Performance & Results

Water Quality Improvements

Environmental & Economic Benefits

• 100% wastewater recycled into production

• Reduces freshwater consumption by 3,600 m³/day

• Meets strict ZLD regulations with reliable performance

• Payback period under 3 years through water savings

Conclusion：Photovoltaic Material Wastewater Treatment

This photovoltaic material wastewater recycling system sets a new standard for sustainable solar panel manufacturing. By implementing MBR, chemical precipitation, and dual RO technologies, manufacturers can achieve zero liquid discharge while maintaining cost efficiency. For photovoltaic companies seeking eco-friendly water treatment solutions, this project proves that industrial wastewater reuse is both practical and profitable.
