“…Interfacial polymerization by aqueous and organic phase coating is an assuring method to fabricate thin-film membranes [26]. In a work by Sutedja et al, they prepared a TFC membrane by interfacial polymerization on the PSf support for separating the textile dyes from wastewater and achieved 88% dye rejection [27]. An improvement in the separation abilities of the membranes can also be attributed to modifying the polysulfone support.…”

Nowadays polymer-based thin film nanocomposite (TFN) membrane technologies are showing key interest to improve the separation properties. TFN membranes are well known in diverse fields but developing highly improved TFN membranes for the removal of low concentration solutions is the main challenge for the researchers. Application of functional nanomaterials, incorporated in TFN membranes provides better performance as permeance and selectivity. The polymer membrane-based separation process plays an important role in the chemical industry for the isolation of products and recovery of different important types of reactants. Due to the reduction in investment, less operating costs and safety issues membrane methods are mainly used for the separation process. Membranes do good separation of dyes and ions, yet their separation efficiency is challenged when the impurity is in low concentration. Herewith, we have developed, UiO-66-NH2 incorporated TFN membranes through interfacial polymerization between piperazine (PIP) and trimesoyl chloride (TMC) for separating malachite green dye and phosphate from water in their low concentration. A comparative study between thin-film composite (TFC) and TFN has been carried out to comprehend the benefit of loading nanoparticles. To provide mechanical strength to the polyamide layer ultra-porous polysulfone support was made through phase inversion. As a result, outstanding separation values of malachite green (MG) 91.90 ± 3% rejection with 13.32 ± 0.6 Lm−2h−1 flux and phosphate 78.36 ± 3% rejection with 22.22 ± 1.1 Lm−2h−1 flux by TFN membrane were obtained. The antifouling tendency of the membranes was examined by using bovine serum albumin (BSA)-mixed feed and deionized water, the study showed a good ~84% antifouling tendency of TFN membrane with a small ~14% irreversible fouling. Membrane’s antibacterial test against E. coli. and S. aureus. also revealed that the TFN membrane possesses antibacterial activity as well. We believe that the present work is an approach to obtaining good results from the membranes under tricky conditions.

“…The fluxes were decreased by PSC2 and then increased to the highest fluxes performed by PSC3 and PSC4, which are similar to the previous study by other researcher. 16 Due to the highest value for dyes flux compared to other samples, it can be concluded that the PSC3 is the most porous clay for the dyes treatment process. 350ppm and 500ppm.…”

Effective treatment of dyes wastewater is important to prevent water pollution. According to data by the Department of Environment (DOE) in 2017, 51 rivers have been polluted because of sewage, industry growth, livestock breeding and attitude of some irresponsible Malaysians that dump trash into river. One of the industries that contribute to river pollution is the batik industry. This is because batik processing activities have resulted in effluents containing chemicals streamed into the river and affecting aquatic life and human health as well. The main goals of this project is to produce a filter from available locally materials in solving polluted river water arising from batik wastewater. Along with the theme “from nature back to nature”, PadS-Clay Filter were prepared from 100% waste material such as paddy straw and clay according to designed formulation. Then, the dyes wastewater was flow on the PadS-Clay Filter and passed through the filter. The UV-Vis spectrophotometer was used to analyze the absorption and concentration of the filtered dyes wastewater. Based on the result, PadS-Clay 2 (PSC2) and PadS-Clay 3 (PSC 3) were the most effective designed formulation for dyes rejection and flux of dyes in treating dyes effluent as the percentage of the dyes rejection for all PSC2 were over than 90%.

“…NF also has a strong role in other branches of the food industry [ 16 ], for example, the beverage industry or saccharide recovery [ 17 , 18 , 19 , 20 ]. Membranes used for this size-based separation method are of composite construction with a polyamide or polysulfone selective layer [ 21 , 22 ]. The mechanical and chemical stabilities are excellent (temperature 50–60 °C, pH 1–13, pressure up to 0.5 MPa) [ 7 ].…”

Lactose Mother Liquor Stream Valorisation Using an Effective Electrodialytic Process

The integrated electrodialysis (ED) process supports valorisation of a lactose-rich side stream from the dairy industry, creating an important source of milk sugar used in various branches of the industry. This work focuses on the optimization of the downstream processes before the crystallization of lactose. The process line includes a pre-treatment and desalination by ED of the industrial waste solution of the lactose mother liquor (LML). The LML was diluted to 25% total solids to overcome hydraulic issues with the ED desalination process. Two different levels of electrical conductivity reduction (70% and 90%) of the LML solutions were applied to decrease the mineral components and organic acids of the LML samples. The ED performance parameters such as ash transfer rate (J), the specific capacity (CF) of the ED and specific electric energy consumption (E) were determined and the influence of the LML solution on the monopolar ion-exchange membranes has been investigated. A higher degree of desalination is associated with higher electric energy consumption (by 50%) and lower specific capacity (by 40%). A noticeable decrease (by 12.8%) in the resistance of the anion exchange membranes was measured after the trials whereas the resistance of the cation exchange membranes remained practically unchanged. Any deposition of the alkaline earth metals on the membrane surface was not observed.
