Introducing the PSI MEMBRANE® Pro-Acid NF98 Series, the ultimate high-pressure acid-resistant membrane system. Enhanced with cutting-edge Thin Film Nanocomposite (TFN) technology, this membrane is meticulously engineered to tackle and recycle even the toughest wastewater challenges. With its exceptional productivity, robustness, and resistance to fouling, it offers industrial users a dependable and highly efficient solution. Achieve superior water recovery within Minimal Liquid Discharge (MLD) systems, effectively rejecting TDS levels exceeding 170,000 mg/L, and enjoy the most cost-effective operation.
Key Features:
Working pH Range 0-12:Our acid-resistant and high-pressure membrane excels across a pH range of 0 to 12, ensuring long-term stability and optimal cleaning efficiency.
Exceptional Anti-Fouling Capability:Featuring a robust and fouling-resistant TFN membrane, enjoy unparalleled long-term performance and reliability.
Unmatched Cost Efficiency:Capable of rejecting system total dissolved solids (TDS) levels of 170,000 mg/L, this system significantly reduces concentrate stream volume while maintaining standard operational efficiency.
Professional Technical Service:Our team of national-level experts delivers first-class technical support to ensure seamless client experiences.
Key Applications:
Ingeniously crafted for the treatment of industrial acidic wastewater in treatment plants. Ideal for Industrial Minimum- and Zero-Liquid Discharge (MLD/ZLD) processes.
Perfect for industrial resource recovery and recycling in sectors such as metals, new energy lithium extraction from lakes, chemical, and petrochemical industries.
