“…The most significant factors for process control are the applied pressure in extrusion and the rate of extrusion. The diameter of the raw material, the amount of binder, and the sintering temperature on the support affect the qualities and performance of the synthesized membrane [ 92 , 93 ] . Huang et al synthesized coal fly ash based ceramic membrane with high efficiency for water and heat recovery.…”

“…These industries are among the many causes of water pollution, producing excessive discharges of highly toxic dyes. The textile industry produces 54% of the dye effluents in the environment, which are potentially toxic and cause serious pollution of the ecosystem and human health (Ağtaş et al 2021;Qin et al 2021). However, most organic dyes are difficult to degrade under natural conditions due to their structural stability and high solubility (Lin et al 2019).…”

The present research work revolves around the evaluation of the elimination of the cationic dye Methylene Blue (MB) from an aqueous solution by the exploitation of natural clay (TMG) from South-East Morocco. Several physicochemical techniques were used to characterize our TMG adsorbate, namely: X-ray diffraction (XRD), Fourier transform infrared absorption spectroscopy (FTIR), differential thermal analysis (DTA), thermal gravimetric analysis (TGA), and zero charge point (pHpzc). The morphological properties and elemental composition of our material were identified using scanning electron microscopy coupled with an energy-dispersive X-ray spectrometer (SEM-EDS). The batch technique was used under different operating conditions to produce quantitative adsorption, namely the amount of adsorbent, dye concentration, contact time, pH, and solution temperature. The maximum adsorption capacity of MB on TMG was 81.185 mg g-1 for a concentration of 100 mg L-1 MB at pHinitial= 6.43, temperature 20 °C, and 1 g L-1 adsorbent. The adsorption data were examined by Langmuir, Freundlich, and Temkin isotherms. The Langmuir isotherm provides the best correlation with the experimental data, and the pseudo-second-order kinetic model is more appropriate for the adsorption of the MB dye. The thermodynamic study of MB adsorption indicates that the process is physical, endothermic, and spontaneous. The Box-Behnken method was applied to identify the optimal conditions for MB removal in the design of batch experiments. The parameters examined result in >99% removal.

“…Among the various components in wastewater, particulate matter is relatively easy to remove from the effluent because it can be separated by filtration [35][36][37][38], floatation [39], and/or sedimentation [33]. Therefore, removal of sludge and suspended solids from wastewaters is not technically difficult.…”

Beverage industries often discharge large amounts of organic matter with their wastewater. Purification of the effluent is their obligation, but it is nontrivial. Among wastewater components, removal of dissolved organic matter often requires much effort. Therefore, a special effective technique must be considered. Microbubbles (1–100 μm) have several special properties of relevance to wastewater treatment. In this study, the effectiveness of microbubbles for treating and purifying beverage wastewater was evaluated. Orange juice, lactic acid drink, and milk were used as model substrates of dissolved organic matter, and degradation experiments were carried out. Rates of air supply by microbubbles were 0.05% (air/wastewater) min−1. Results indicated that the total organic carbon (TOC) in an experimental vessel containing milk (high nitrogen content) decreased by 93.1% from 11.0 to 0.76 g during a 10-day incubation. The TOC of lactic acid drink (least nitrogen content) decreased by 66.3%, from 15.6 to 5.26 g, and the TOC of orange juice (medium nitrogen content) decreased by 82.7%, from 14.8 to 2.55 g. Large amounts of particulate organic matter floated on the water surface in the milk with microbubbles and were removed easily, while almost no floating materials were observed in the orange juice and lactic acid drink. In contrast, in the macrobubble treatment (diameter 0.1 to 2 mm), only 37.0% of TOC in the milk was removed. Whereas the macrobubble treatments were anaerobic throughout the incubations, the microbubble treatments returned to aerobic conditions quickly, and brought 10 times greater bacterial abundances (>108 cells mL−1). These results suggest that microbubbles are much superior to macrobubbles in supplying oxygen and accelerating the growth of aerobic bacteria, and that wastewater containing more nitrogenous compounds was purified more effectively than that with less nitrogen by microbial degradation and floating separation.
