Industrial NF Membranes

Alkalistab Series alkaline resistant nanofiltration membrane elements are designed for water and wastewater applications operating under high-pH conditions where conventional NF membranes rapidly degrade.   They provide stable separation performance and long service life in alkaline cleaning, process water reuse, and chemical wastewater treatment systems. Key Technical Highlights Stable nanofiltration performance under continuous alkaline operation Enhanced chemical resistance to caustic cleaning and high-pH feed water Reliable separation of multivalent ions and organic compounds Consistent flux and rejection for long-term industrial use Compatible with standard NF system configurations Customer Value Reduced membrane replacement frequency in alkaline processes Improved system reliability during frequent CIP and high-pH operation Lower operational risk in industrial and municipal water treatment systems Proven solution for challenging alkaline water and wastewater applications

ENF Series water treatment nanofiltration membrane elements are designed for applications where conventional filtration cannot effectively remove organic matter, color, and multivalent ions.   They are widely applied in municipal and industrial water treatment systems to improve treated water quality while maintaining stable flux and energy-efficient operation. Key Technical Highlights Selective removal of organic matter, color, and multivalent ions Stable separation performance under variable feed water conditions High permeate flux with low operating pressure Balanced water recovery and rejection efficiency Compatible with standard nanofiltration system designs Customer Value Improves treated water clarity, color, and overall quality stability Reduces operating pressure and long-term energy consumption Enhances system reliability for continuous municipal operation Supports long service life with standard cleaning procedures

Acidstab Series acid-resistant nanofiltration membrane elements are designed for stable separation and recovery in acidic and corrosive process streams where conventional NF membranes fail.   They are widely applied in acid recovery, metal separation, and chemical wastewater treatment to improve system reliability and reduce membrane replacement frequency. Key Technical Highlights Stable separation performance under acidic conditions High resistance to hydrochloric, nitric, and sulfuric acid solutions Effective recovery of metal ions and valuable components Consistent flux and rejection in corrosive process environments Designed for continuous industrial operation Customer Value Enables reliable operation in acidic and corrosive water treatment processes Reduces membrane damage and unplanned shutdowns in harsh conditions Supports acid recovery and resource reuse, lowering operating costs Proven solution for industrial systems requiring long-term stability
