Acidstab NF Series of acid-resistant nanofiltration membrane elements are mainly used to separate metal ions/inorganic salts from acid solutions to achieve permeation and recovery of acid solutions. It can be used in 20% (ω/%) hydrochloric acid, nitric acid and sulfuric acid, with molecular weight cutoff at about 200 Dal rejected.
