Supply DK8040F nanofiltration

GE nanofiltration D Series DK4040/8040 
 D Series proprietary composite nanofiltration membrane MWCO of 150-300 daltons (neutral molecular computing), 
 Applications: remove or concentrated dyes, heavy metals removal, the purified acid, sodium chloride leaching, the concentration of sugar and grading, and the desalination of whey protein concentrate, titanium concentration and desalting 
 Of divalent and multivalent anions priority retention, retention rate of the unit size and ionic liquid concentration and composition of relevant, due to price ions through the membrane, no osmotic pressure, so the D-Series system can be compared with anti-NF infiltration systems to run at lower operating pressures. 
 DK nanofiltration membrane element flux standard fiberglass shell with thick conduit and standards. Other structures may be needed to use materials and special design flow.
