“…The relatively low TOC removal efficiency indicates that textile wastewater contains low molecular weight organic matter [ 36 ]. Alardhi et al [ 37 ] confirmed the success of dye removal with UF hollow fiber membranes, and Sherhan et al [ 38 ] also indicate high removal of turbidity of 95% and TOC of 96%.…”

The aim of this study was to investigate the best pretreatment of textile wastewater (TWW) for membrane separation processes and the previously unexplored reuse of treated TWW for washing dyeing machines. Sand filtration (SF), coagulation, coagulation/flocculation, and ultrafiltration (UF) with hollow fiber membrane (ZW1) were used for pretreatment. Pretreatment selection was based on turbidity, total organic carbon (TOC), and color. SF and ZW1 were found to be the best pretreatments. In addition, the SF and ZW1 effluents were subjected to the 5 (PT) and 50 (MW) kDa UF flat sheet membranes to test removal efficiency. ZW1-PT was better in terms of removal results and fouling. To reduce the use of drinking water for washing dyeing machines, the characteristics of ZW1-PT effluent were compared with drinking water from a textile factory. TWW treated with this hybrid process fulfils the purpose of reuse for washing dyeing machines and can be used in Galeb d.d., Croatia, or in any other textile factory, saving up to 26,000 m3 of drinking water per year. This contributes to both sustainable production and the conservation of water resources.

This search aim to study the feasibility of hydro-desulfurization (HDS) of gas oil in fixed bed reactor by using economic support catalyst alumina meta kaolin (AMK) under various operating condition, i.e. Temp. (240−320 ◦C), Press. (3–12 bar), WHSV (2–6 h−1) at H2/HC ratio (50 vol./vol.). The support catalyst was prepared from Iraq kaolin and characterization by using scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX) and Fourier transform infrared (FTIR) spectroscopy. Experimental design was used to determine which parameter (e.g. temperature, pressure and WHSV) has a greater influence on the obtained HDS and the optimum condition of process. The result shows that optimum condition given (Temp. 300 C, Press. 12 bar and WHSV 2 h-1) and all parameter have significant implication in the process.

“…It must therefore be effectively handled according to priority (Al-Tohamy et al 2022). To remove dyes, a number of separation methods, such as physical and chemical ones (membrane filtration, coagulation, flocculation, and adsorption) (Alardhi et al 2023) biological ones (anaerobic and aerobic treatment) (Vashisht et al 2022), and chemical ones (photo-Fenton reaction, ozonation) (Tanveer et al 2022). In order to completely mineralize hazardous and non-biodegradable molecules, heterogeneous photocatalysis is favored, circumventing the drawbacks of physical and biological approaches (Ashraf et al 2022).…”

Triple transition (Ni, Cu, and Zn) doped hematite nanoparticles (α-Fe2O3 NPs) have made significant advances in biological, environmental, as well as other interdisciplinary fields of study, due to their stability and relative lack of toxicity. The α-Fe2O3 NPs has been made simple, effective, and ecologically benign by utilizing the reducing and capping capability of Azadirachta indica aqueous leaf extract. Synthesized material has been studied by XRD, UV-visible, Raman, FTIR, VSM, SEM, and TEM techniques. Doped α-Fe2O3 NPs possessed a rhombohedral phase and corundum structure that was exceptionally pure and well crystalline. The synthesized α-Fe2O3 NPs had a size of 22.83 nm and were irregular-spheroidal in shape, according to SEM and TEM examination. Synthesized NPs show ferromagnetic characteristics, according to VSM research. The photocatalytic activity of doped α-Fe2O3 NPs was evaluated by methyl orange (MO) (95%), methylene blue (MB) (97%), congo red (CR) (92%), and eosin yellowish (EY) (90%) efficiently dyes degradation, when exposed to visible light for 90–100 minutes. As a result, the NPs are suited for applications where reusability is a crucial essential feature due to the modest drop in the photocatalytic activity after four cycles. This current study examines the effects of α-Fe2O3 NPs on the seed germination of Vigna radiata (mung bean) and phytotoxicity study biomass accumulation Allium cepa (onion) through a series of germination assays. For this reason, it is crucial to manage the materials size, morphology, and magnetic properties in order to produce well-tailored photocatalysts.
