SHUIYI Reclaimed Water and Zero Discharge Nanofiltration Membranes PCNF-8040/4040
PCNF products are highly selective nanofiltration membranes developed for material concentration and separation fields, which are suitable for water reuse, zero discharge of high saline water, and sewage and wastewater resource recovery, etc.
PCNF products are high-precision anti-pollution nanofiltration membranes developed for industrial reclaimed water field, with a retention molecular weight of 200-300 Da. They are characterized by a very high retention rate of organic matter and divalent salts, and can well meet the requirements of scenarios such as decolorization, hard removal and medium desalination.
Features
Dual effect separation
Synergistic regulation of filtration by physical screening and charge rejection
Hydrophilic and anti-fouling
Introduction of hydrophilic groups for wider and more frequent chemical cleaning resistance
On-demand interception
Different retention accuracy can be customized on demand
Secondary polymerization
Inhibit defects on the membrane surface,and is impervious to high concentration of salt
