Use of nanofiltration aromatic polyamide membranes, case study: Influence of operating conditions on the rejection of pb (II) in aqueous solutions at industrial pilot plant

摘要

Nanofiltration membranes have properties that combine size and electrical effects, as those present in UF membranes. NF membranes have also mechanisms of diffusion in solutions, such as the ruling transport in non porous RO (reverse osmosis) membranes [1]. The aim of our research was to analyze the potential use of nanofiltration (NF) polyamide membranes for the removal of lead ions from wastewater [2].
