Regular NF Spiral-wound Membranes

AMESTEC HG-TK/HG-TL/HG-TP regular nanofiltration spiral wound membranes use the special composite membrane that adopts an uncharged organic molecule to intercept a molecular weight cutoff of approximately 150-300 Daltons, which enables monovalent salts to pass and intercepts the divalent salts. 

Industry application

Mainly used in dye desalination and concentration, heavy metal removal, sodium chloride diafiltration, sugar separation, whey protein concentration and desalting, peptide concentration and desalination.
