PV Wastewater Treatment: Kintep's Advanced Solution in Action
The photovoltaic (PV) industry is expanding at an unprecedented pace, driving global renewable energy adoption. However, this rapid growth brings environmental challenges, particularly in managing PV wastewater. As international attention shifts toward sustainable manufacturing, effective treatment of PV wastewater has become a critical focus.
The Complexity of PV Wastewater
PV wastewater originates from processes such as cutting, grinding, and slicing silicon rods, as well as polishing and etching silicon wafers. It contains:
• High concentrations of organic compounds like polyethylene glycol (PEG).
• Suspended Solids including silicon powder and silicon carbide.
• Harmful chemicals such as fluoride ions, nitric acid, hydrofluoric acid, and other buffering agents.
These components make PV wastewater difficult to treat, requiring specialized systems to meet discharge or reuse standards.
Kintep’s Integrated Treatment System for Water Recovery
Our tailored solution for PV wastewater combines precision and efficiency:
Reaction System (coagulation and flocculation) → Lamella Clarifier (solid-liquid separation) → Automatic Filter Press (Sludge Dewatering)
With this system, you achieve significant sludge reduction and enable high-quality water reuse.
Case Study: Success in Jiangsu Client
In our project for a PV manufacturer in Jiangsu China, the client already had sedimentation equipment in place. We integrated our automatic filter press to optimize their sludge treatment process.
Key Results:
• Sludge Type: Solar PV wastewater sludge
• Initial Moisture Content: 97.5%–85%
• Operation: Automated, continuous operation for 5 hours and 15 minutes
• Output: ~730 kg of sludge across 4 bags
• Efficiency: ~139 kg of sludge per hour
• Final Moisture Content: 48% as measured by AMKS
The treated sludge, shown in the images, demonstrated volume reduction and stability, ready for safe transport and disposal.
Global Trends in PV Wastewater Management
Internationally, regulatory frameworks are tightening, with an increased emphasis on:
• Zero-liquid discharge (ZLD) and water recycling.
• Advanced sludge dewatering to minimize waste volume.
• Sustainable chemical management to reduce environmental impact.
Kintep’s systems align with these trends, offering scalable, efficient, and eco-friendly solutions for the PV sector.
