Treatment of textile plant effluent by hollow fiber nanofiltration membrane and multi-component steady state modeling

Use of rhamnolipid in micellar‐enhanced ultrafiltration for simultaneous removal of Cd+2 and crystal violet from aqueous solution

“…According to several studies reported in literature, the concentrations of dyes, total dissolved solids, and NaCl in the typical textile effluent vary from 10–200, 1,500–13,000, and 1,000–10,000 mg/L, respectively . Also, pH of the textile wastewater is found to vary in the range of 6.7–11.2. The poor waste management and improper disposal of industrial effluents, particularly in developing countries, can be the reason of mixing of different effluents, resulting in existence of both heavy metal ions and organic dyes in wastewaters .…”

“…They are generally characterized in terms of biochemical oxygen demand, chemical oxygen demand, total dissolved solids, color, salinity, and pH . According to several studies reported in literature, the concentrations of dyes, total dissolved solids, and NaCl in the typical textile effluent vary from 10–200, 1,500–13,000, and 1,000–10,000 mg/L, respectively .

Synthesis and Adsorption Properties of Novel Bacterial Cellulose/Graphene Oxide/Attapulgite Materials for Cu and Pb Ions in Aqueous Solutions

“…Excessive enrichment of metals such as Cu (II) and Pb (II) in human body can lead to serious damage to different organs and diseases of cardiovascular, nervous system and immune system [ 3 , 4 ]. Typical methods such as adsorption, filtration, biological treatment, chemical degradation, and membrane separation are used to treat industrial sewage [ 5 , 6 , 7 ]. Moreover, adsorption has been identified as one of the most cost-effective treatments due to its unique advantages such as simple operation, low cost and high removal rate for metal ions [ 8 , 9 , 10 ].…”

Preparation and performance of biofouling resistant PAN/chitosan hollow fiber membranes

“…Biocidal activity was achieved by functionalizing sepiolite fibers with Ag (26 wt%) and Cu (26 wt%), which were embedded in the fiber surface. He achieved that the effect was particularly intense for Ag-sepiolite in contact with Saccharomyces cerevisiae, where the reduction amounted to 85% compared to neat PLA (control) (Mondal and De 2016) and Sawada et al) prepared acrylamide grafted onto a polyethersulfone (PES) hollow fiber membrane and silver nanoparticles were then formed within the acrylamide layer. Antibacterial activity of the silver-loaded membrane was evaluated against Escherichia coli (E. coli) using the halo zone test with an agar culture medium.…”
