These new generation ultrafiltration membranes developed and manufactured by permionics are hydrophilic polyethersulphone membranes with a thin film oxidation resistant layer. These membranes have a higher flux and a sharper mwco, than the equivalent unmodified membranes of the same mwco.
Type hfuf 30,flux [lmh] at 50 psi 110-130, mwco-30-50 kd, applications:-• pretreatment of waste & surface water,enzyme concentration,colloidal silica removal.
Type hfuf 15, flux [lmh] at 50 psi 80-100, mwco:15-20 kd, applications:• concentration of proteins,whey fractionation, gelatine concentration.
Flux measured at 25 deg c on tap water
These membranes are more rugged than unmodified pes uf membranes in terms of
Chlorine tolerance : 5 ppm continuous; 100 ppm shock cleaning
