Microfiltration and ultrafiltration are used for the purification process of stevia extract to retain steviosides remove tannins. The main objective this study was obtain operating conditions that resulted in lowest stevioside rejection highest tannin rejection. using microfiltration membrane carried out at transmembrane pressure (1.20, 1.40, 1.65, 1.80, 1.90 bar), cross flow velocity (0.04, 0....

Carbon nanotubes (CNTs) with hollow nanochannels have attracted much attention in preparing high-performance water treatment membranes. In this paper, the grafting polymer chains, including alkynyl terminated poly(methyl methacrylate) methacrylate (PMMA) single chain and PMMA-b-poly (ethylene glycol) [P(PEGMA)] diblock molecular were synthesized by reversible addition-fragmentation transfer (RA...
