Introducing the PSI MEMBRANE® Pro-Acid NF98 Series, a pinnacle of high-pressure acid-resistant membranes. Integrated with cutting-edge Thin Film Nanocomposite (TFN) technology, this membrane is meticulously crafted for the treatment and recycling of challenging wastewater. Its high productivity and durable, fouling-resistant design furnish industrial users with a steadfast and efficient solution, perfect for achieving water recovery within Minimal Liquid Discharge (MLD) systems. Capable of rejecting Total Dissolved Solids (TDS) levels exceeding 170,000 mg/L, this membrane offers the most cost-effective operation possible.
Key Features:
Working pH 0-12:Our acid-resistant, high-pressure membrane excels in a pH range of 0-12, ensuring long-term stability and outstanding cleaning efficiency.
Excellent Anti-fouling:Crafted with a robust, fouling-resistant TFN membrane, it guarantees reliable, long-term performance.
Unmatched Cost Efficiency:This system is expertly designed to reject a total dissolved solids (TDS) level of 170,000 mg/L, efficiently reducing concentrate stream volume during standard operations.
Professional Technical Service:Our elite national-level expert team is dedicated to delivering first-class technical support to all clients.
Key Applications:
Engineered specifically for industrial acidic wastewater treatment plants, offering unparalleled efficacy. Perfect for Industrial Minimum- and Zero-Liquid Discharge (MLD/ZLD) applications.
Ideal for industrial resource recovery and recycling applications, such as metal processing, new energy lithium extraction from lakes, and the chemical & petrochemical industries.
Efficient in water softening processes, enhancing overall water quality.
