Industrial Solar Nanofiltration Wastewater Treatment System with 1-10nm Membrane Pores and 0.5-1.5 MPa Operating Pressure

The industrial solar nanofiltration system integrates renewable solar power with advanced membrane filtration technology for industrial wastewater recovery and purification. This innovative solution is particularly suitable for industrial applications with limited power infrastructure or energy reduction requirements.

• Solar-powered operation reduces traditional electricity consumption and carbon emissions
• Chemical-free process eliminates secondary pollution risks
• Energy storage compatibility enables 24/7 operation capability

• Simultaneous desalination, decolorization, and trace pollutant removal
• Stable effluent quality meeting discharge standards
• Effective removal of heavy metal ions, organic compounds, and hardness ions

• Acid/alkali resistant membrane materials (polyamide, ceramics, composites)
• Anti-fouling properties for complex industrial wastewater environments
• Adaptable to various regional lighting conditions

• Flexible scalability based on treatment volume requirements
• Easy installation and system expansion
• Chemical cleaning and physical flushing regeneration capabilities
• Low maintenance costs with extended service life

• Industrial wastewater reuse in electronics, electroplating, chemical, pharmaceutical, and textile industries
• Water-scarce regions for seawater desalination and brackish water purification
• Remote industrial parks and mining areas without grid infrastructure
• Sustainable industrial development projects requiring low-energy solutions

The treatment process begins with pretreatment (screening and sedimentation) to remove large particles, followed by solar-powered nanofiltration at 0.5-1.5 MPa pressure. The system achieves selective pollutant removal through screening effects, charge repulsion, and diffusion/adsorption mechanisms, producing high-quality treated water suitable for reuse or standard discharge.
