Unique Alkali-Resistant Membrane Element 8040
Pro-Base Series – Alkali-Resistant Special Separation Spiral Membrane Element
The Pro-Base Series is engineered with the proprietary PSI MEMBRANE® TFN alkali-resistant membrane and advanced acid-resistant construction materials, delivering superior durability and consistent separation performance in harsh chemical environments. This high-performance membrane element is specifically designed for strong alkali processing, ensuring stable operation, extended lifespan, and optimal productivity.
Key Features
Exceptional alkali resistance, withstanding up to 20% sodium hydroxide and 10% potassium hydroxide.
Advanced anti-fouling properties, large water flux capacity, high-pressure tolerance, and superior limit-alkali resistance.
Extended service life-over 12 months of stable operation in strong alkali conditions while maintaining high flux and reliable separation efficiency.
Key Applications
Concentration of cellulose, hemicellulose, papermaking fibers, and other valuable compounds.
Purification and recycling of alkaline solutions for improved resource efficiency.
Widely applied in mining, metallurgy, pulp and paper, rayon, chemical processing, pharmaceuticals, and the food & beverage industry.
The Pro-Base Series MEMBRANE is the ideal choice for industries that require reliable separation performance in high-alkali and chemically demanding conditions. Its combination of proprietary membrane technology, robust materials, and optimized spiral design ensures consistent results, reduced downtime, and long-term operational cost savings.
