TL;DR: In this article, four nanofiltration membranes, two negatively and two positively charged, were fabricated by interfacial polymerization, and three different amines, ethylenediamine (EDA), diethylenetriamine (DETA), and hyperbranched polyethyleneimine (PEI), were selected to react with two acyl chlorides, trimesoyl chloride (TMC) and terephthaloyl chloride (TPC).

TL;DR: In this paper, negative charged thin-film-composite polyamide nanofiltration (NF) membranes were used to filter aqueous calcium sulfate solution, examining potential for water softening application.

TL;DR: In this paper, a review of membrane processes that may be used in zero liquid discharge (ZLD) approaches is presented, as well as potential solutions and innovative technologies for improving their performance.

TL;DR: In this paper, negatively charged polyamide thin-film-composite nanofiltration membranes have been used to possibly treat the sodium-enriched water, particularly cooling tower water, to separate hardness producing solute like MgSO4 from univalent salts using ESNA and EDA.

TL;DR: In this article, two hydrophobic alumina hollow fiber membranes were used for sucrose concentration in a vacuum membrane distillation (VMD) system, which achieved high mechanical strength of 191 MPa, high water contact angle of 140° and high liquid entry pressure of 5.0 bar.
