“…Aerobic MBRs have been investigated by several authors for treatment of synthetic textile wastewater [ 14 , 15 , 43 , 44 ]. Konsowa et al [ 15 ] investigated synthetic textile wastewater containing red dye CI81 and they found COD removal rates between 90.9%–95.6% at 1−3 g/L of MLSS concentrations.…”

“…Deowan et al [ 43 ] also investigated synthetic textile wastewater and 90 % COD removal efficiency and between 20–50% color removal efficiencies were obtained at 12 g/l MLSS and 0.5 bar of TMP at a constant pressure mode of MBR operation. Synthetic textile wastewater treatment was also investigated by Friha et al [ 44 ] and COD and color removal efficiencies were found 98 % and 100 % at a constant pressure mode of MBR operation (0.07−0.35 bar). Yurtsever et al [ 14 ] researched treatment of textile wastewater containing 1000 mg/L COD and 100 mg/L Remazol Brilliant Violet 5R, and they found 97 % COD removal and partial color removal efficiencies (between 30–50%) at 20 LMH of membrane flux.…”

“…The mean fluxes were found as 5.47 and 5.83 L/m 2 .h during the MB-MBR operation with the biocarrier filing ratios of 20 % and 10 %, respectively. Looking at previous studies on treatment of textile wastewater in aerobic MBRs, the flux value was kept between 2 and 8 L/m 2 .h [ 44 , [59] , [60] , [61] ]. However, higher flux values in treatment of textile wastewater by MBR have also been applied by some researchers [ 14 , 15 ].…”

“…Hspa8 was also revealed to contribute to the regulation of cancer cell growth by secretion in the extracellular environment ( 61 ). Abnormal Hspa8 expression has also been observed during stress responses following exposure to linear alkylbenzene sulfonate and other chemical pollutants ( 62 , 63 ). In the present study, upregulation of Hspa8 and Hspa9 revealed that MTBE exposure induced affected HSP expression.…”

Methyl tert-butyl ether (MTBE) is widely used as an oxygenating agent in gasoline to reduce harmful emissions. However, previous studies have demonstrated that MTBE is a cytotoxic substance that has harmful effects in vivo and in vitro. Although remarkable progress has been made in elucidating the mechanisms underlying the MTBE-induced reproductive toxicological effect in different cell lines, the precise mechanisms remain far from understood. The present study aimed to evaluate whether mammalian ovary cells were sensitive to MTBE exposure in vitro by assessing cell viability, lactate dehydrogenase (LDH) leakage, malondialdehyde (MDA) content and antioxidant enzyme activities. In addition, the effect of MTBE exposure on differential protein expression profiles was examined by two-dimensional electrophoresis and matrix-assisted laser desorption/ionization-time of flight mass spectrometry. MTBE exposure induced significant effects on cell viability, LDH leakage, plasma membrane damage and the activity of antioxidant enzymes. In the proteomic analysis, 24 proteins were demonstrated to be significantly affected by MTBE exposure. Functional analysis indicated that these proteins were involved in catalytic activity, binding, structural molecule activity, metabolic processes, cellular processes and localization, highlighting the fact that the cytotoxic mechanisms resulting from MTBE exposure are complex and diverse. The altered expression levels of two representative proteins, heat shock protein family A (Hsp70) members 8 and 9, were further confirmed by western blot analysis. The results revealed that MTBE exposure affects protein expression in Chinese hamster ovary cells and that oxidative stress and altered protein levels constitute the mechanisms underlying MTBE-induced cytotoxicity. These findings provided novel insights into the biochemical mechanisms involved in MTBE-induced cytotoxicity in the reproductive system.

“…Recently, the treatment of wastewater containing azo dyes has received a lot of interest in different forms such as biological degradation, chemical coagulation, and chemical. Due to the ineffective biological and chemical treatment processes, so that the membrane filtration processes have been used as suitable and effective dyeing wastewater treatment methods [9]. On the other hand, conducting polymers have been commonly used in various applications due to their interesting properties [10].…”

I N THIS study, cotton and polyester textile fabrics have been treated with polyaniline layer to use as smart filter for industrial wastewater treatment. The developed filters were effective to anchor the dissolved dye wastewater molecules. The polymerization of polyaniline chains on textile fabrics was assured by microscopic techniques. Also, the electrical resistance of treated samples was significantly reduced recording 20 and 40 kΩ for cotton and polyester-PANI filter respectively. The textile-based filter was tuned to be selective to negative dye molecules dissolved in water. The mass ratio of dissolved dyes was varied with developed filter and achieved 45% removal efficiency. The developed textile-based filter was characterized using various spectroscopic and microscopic techniques. The concentration of waste dyes molecules before and after treatments was determined and efficiency of filter was evaluated.
