With the surging global demand for renewable energy, the European photovoltaic industry is experiencing unprecedented development opportunities. However, the manufacturing of monocrystalline silicon and polycrystalline silicon, which are at the core of the photovoltaic industry chain, is also a highly water-consuming sector. Particularly in the processes of ingot cutting, slicing, and cleaning, a large amount of grinding wastewater containing silicon powder, PEG (polyethylene glycol), and silicon carbide is generated. 

The "Water" Challenge and Environmental Pressure in Photovoltaic Manufacturing 

The traditional straight discharge or simple tsareatment methods not only waste precious water resources, but also pose a threat to the environment due to their high concentrations of suspended solids and chemical oxygen demand (COD). Europe has the world's strictest environmental protection regulations, which impose extremely high requirements on the discharge and recycling rate of industrial wastewater. Therefore, achieving "reclaimed water reuse" and even "zero wastewater discharge" has become a must for photovoltaic manufacturing enterprises to gain a foothold in the European market. 

Baihui Pu Environmental Protection: Your Reliable Partner for Water Resources Solutions 

Baihui Pu Environmental Protection has been deeply engaged in the industrial water treatment field for many years. In response to the characteristics of wastewater from monocrystalline and polycrystalline silicon production, we have developed an efficient and stable reclaimed water reuse system. This system, through integrated physical, chemical, and membrane separation technologies, can purify the complex production wastewater to a high standard of water quality that can be reused in the production line. 

Core technical advantages of our single/multi-crystalline silicon water reuse equipment: 

1. Efficient pretreatment system: It adopts multi-stage coagulation, sedimentation and air flotation technologies to effectively remove the majority of large particle suspended solids such as silicon powder and silicon carbide in the wastewater, providing reliable protection for the subsequent membrane system. 

2. Core membrane separation technology: The double-membrane process of ultrafiltration (UF) and reverse osmosis (RO) is applied. Ultrafiltration ensures extremely low turbidity and SDI values in the effluent, while reverse osmosis efficiently removes dissolved salts, TOC and trace organic substances, resulting in water quality that exceeds the reuse standards for production lines. 

3. Anti-pollution and Automation Design: In response to the highly polluted nature of the wastewater, we have selected anti-pollution membrane elements and optimized the flow channel design. Coupled with an automatic chemical cleaning (CIP) system, this significantly extends the membrane's lifespan and reduces maintenance costs. The intelligent PLC control system enables unattended operation 24/7. 

4. High recovery rate, contributing to cost reduction and efficiency improvement: The system's water resource recovery rate can reach 75% to 90%, significantly reducing the enterprise's fresh water intake and wastewater discharge fees, directly lowering production costs, and featuring a short investment payback period. 

5. Compliant with European standards: Our equipment fully considers and meets the requirements of the EU CE certification and related environmental protection directives in terms of material selection, electrical safety and energy efficiency design, ensuring customers can use it without worries.
