Integration of microfiltration and nanofiltration to promote textile effluent reuse

Reviewing textile wastewater produced by industries: characteristics, environmental impacts, and treatment strategies

“…This membrane is primarily used to remove particulate suspensions and colloidal dyes from the load-running dye baths and out-of-date rinsing bath (Dasgupta et al 2015). MF supports unconsumed auxiliary chemicals, dissolved organic pollutants, ions, and other soluble pollutions to pass through the membrane together with the permeability (Couto et al 2017). Amaral et al (2014) studied the use and operating parameters of the MF system to recover insoluble indigo blue present in the cotton yarn dye bath to realize pigment reuse and water washing.…”

Hydroxypropyl-β-cyclodextrin-incorporated Pebax composite membrane for improved permselectivity in organic solvent nanofiltration

“…8b ). This behaviour may be explained by an enhancement of the methanol mass transfer coefficient, 60 thanks to the decrease in the temperature-dependent viscosity of the methanol solution. Moreover, with increasing the operating temperature, a dilatation in the pore sizes occurred, which facilitated the transport of solutes through the membrane and reduced the concentrations in the membrane pores and on the membrane surfaces.…”

“…Moreover, with increasing the operating temperature, a dilatation in the pore sizes occurred, which facilitated the transport of solutes through the membrane and reduced the concentrations in the membrane pores and on the membrane surfaces. 60,61 Based on the above-mentioned investigations, a comparison of the OSN performances among the optimal CHP 0.5-10 membrane and the previously reported membranes 62 is presented in Table 2. The results indicated that the CHP 0.5-10 membranes were markedly superior to those in previous reports, revealing the outstanding effect of HP-b-CD in preparing an OSN membrane for potential application in the decolorization of textile dyeing industry effluent.…”

“…Kovaleva et al (2017) found that a dynamic membrane formed during the separation of the molasses broth, which served as an Water Environment Research, Volume 90, Number 10 -Copyright © 2018 Water Environment Federation additional barrier to the solvent and was eventually compacted to retard yeast cells and polysaccharides and passed more than 80% of ethyl alcohol. Couto et al (2017) integrated MF and NF membranes to promote the reuse of textile effluent. The MF membrane efficiently retained indigo blue dye, allowing its recovery from the concentrated stream.…”
