Synder’s Nanofiltration (NF) membranes: Better Rejection, Greater Flux.
The NFX & NFW membranes encompass molecular weight cutoffs (MWCO) from 150-500D and have typically displayed better rejection and greater flux than the leading competitor.  With high rejections of hardness, metals, and organic matter, and lower operating pressures than reverse osmosis membranes, Synder's NF membranes and systems are the economical option in certain water treatment applications.  Contact us today to find a solution for you.  

Common Applications
Hardness, Heavy Metal, Nitrate, Sulfate, Tannin, Odor, Color, and TDS Removal: Water Treatment  
Lactose Concentration: Dairy  
Dealcoholization, Fragrance Recovery, Maple Syrup Concentration: Food & Beverage 
Blood Serum: Antibiotics  
Polyvinyl Alcohol Recovery: Textile 
Precious Metal Recovery: Mining  
Coal Bed Methane Processing: Natural Gas  

Features & Benefits of Synder's NF Membranes 
Flexibility with two models and , the NFX & NFW
Better Rejection with a minimum 98% and 99.3% MgSO4 rejection by the NFW and NFX membranes, respectively 
30-50% Greater Flux than the leading competitor  


Reverse Osmosis

Ultrapure Water Production
Synder’s Reverse Osmosis (RO) membranes and systems can produce large volumes of ultrapure water with incredible efficiency.  As illustrated below, through the application of pressure to concentrated solutions, water molecules can be driven through a membrane against natural osmotic pressure.  This membrane separates these water molecules from all dissolved solids and other contaminants, thus producing ultrapure water.  Significantly more energy and time efficient that other conventional processes,  Synder's RO technology is the ideal choice when economical ultrapure water treatment is a necessity.  

Pretreatment typically a necessity for optimum RO performance.  Synder can provide UF and NF membranes and systems to prevent fouling and protect the RO membranes.
