The photovoltaic industry generates fluoride-containing wastewater (fluoride concentration: 200–5000 mg/L) primarily from silicon wafer cutting, etching, and cleaning processes. Excessive fluoride discharge poses significant environmental risks. Traditional chemical precipitation methods struggle to meet stringent emission standards (e.g., Class IV surface water requires fluoride concentration ≤1.5 mg/L). In contrast, ion exchange resin technology, with its high selectivity and deep treatment capability, has emerged as a core solution for achieving near-zero fluoride emissions in the photovoltaic sector.

Kingshan JK-F is a high-performance fluoride removal resin based on a styrene-divinylbenzene (S-DVB) matrix with composite functional groups. It exhibits exceptional selectivity for fluoride ions, offering high adsorption capacity, low leakage levels, and simple regeneration, all while maintaining lower operational costs than comparable products.

Key Advantages:

1.Precise Fluoride Adsorption: The resin forms specific bonds with fluoride ions, ensuring priority adsorption even in the presence of competing anions (e.g., sulfate, chloride), guaranteeing stable effluent fluoride concentrations ≤1 mg/L.

2.Extended Service Life: The resin can be regenerated and reused for 3–5 years, significantly reducing long-term costs compared to traditional chemical precipitation (which requires frequent replacement of activated alumina or disposal of large sludge volumes).

Typical Applications:

1. A 500 m³/day photovoltaic wastewater treatment project adopted a two-stage resin system, achieving effluent fluoride levels <1 ppm with an operational cost of ~3.8 RMB/ton, representing 40% energy savings over conventional methods.

2. In a Jiangsu photovoltaic industrial park, integrated treatment (coagulation + high-efficiency sedimentation + resin adsorption) reduced fluoride concentration from 8 mg/L to 1.5 mg/L while cutting sludge production by 50%.
