“…Moreover, the data exhibited that carbamate oxidation through the modified Fenton-like system based on alum sludge waste augmented with magnetite nanoparticles typically proceeds at −20.03 kJ mol −1 , that signifies a low energy barrier, which is in agreement with the results of previous data cited in the literature 78 which found the energies of activation for the reaction are located at 45.84 kJ mol −1 , 53.96 kJ mol −1 and −35.85 kJ mol −1 (ref. 28) using oxidation via such a Fenton reaction. Moreover, a negative activation energy value signifies that the rate of reaction declines with increasing reaction temperature and this also supports the abovementioned negative dependence on temperature.…”

“…In order to simplify the model calculations, the natural variables of the operating system ( ε i ) were transformed to coded variables ( ζ i ) in accordance with eqn (1). 28 Moreover, after the experiments were done, the optimal values were located using Mathematica software (V 5.2). Then, a further extra three replicate experiments were conducted to validate the suggested model.…”

“…In parallel, alum sludge powder was prepared according to the previous procedure [33,34]. Initially, the extra water content in the sludge was descanted from the sludge through gravity settling prior to air-drying, thereby resulting in a dried sludge cake containing 10% moisture content.…”

The circular economy concept is leading environmental engineering in the search for “End-of-Waste” criteria. Untreated waste residue results from drinking water treatment plants, causing severe environmental issues, and its reuse is essential. In this regard, this investigation introduces the beneficial reuses of alum sludge cake to close the loop between sludge waste generation and reuse. Considering alum sludge as a resource for dewatering instead of its categorization as a waste reflects an “End-of-Waste” approach. Alum sludge cake was thermally calcined at 400 °C and named thermally treated alum sludge cake (TAS-cake). In this study, TAS-cake decorated with magnetite with a percent weight of 5 to 1%, respectively, was labeled as TAS-cake@Fe-(5-1). X-ray diffraction (XRD) and morphologies were applied to characterize the hybrid composite. A Fenton-based hybrid composite was applied to extrude water from alum sludge for 7 min of conditioning time. Furthermore, the factorial design based on response surface methodology (RSM) was applied to optimize the operational variables. TAS-cake@Fe-(5-1) and hydrogen peroxide revealed 1.2 g/L and 740 mg/L doses at pH 3.0, showing pronounced performance and revealing the highest capillary suction time (CST) reduction, which reached 53%. A temperature increase also showed a pronounced enhancement effect on the sludge dewaterability that reached 72% when 55 °C was applied. Thus, such a novel conditioner is a promising candidate for alum sludge conditioning.

“…Modern society is suffering from a severe global challenge causing environmental water deterioration due to modern aquaculture activities (Thabet et al, 2022a). Crude oil and its derivatives could travel thousands of miles and over dozens of hands prior to their final use (Tehrim et al, 2021;Thabet et al, 2022b).…”

The essential target of academics and the industrial sector is the innovation of an industrial ecology approach. Worldwide, cigarette butts (CBs) comprise the most predominant form of litter that spreads into the ecosystem and inland. In the meantime, oil is spilled into marine life from various activities and transportation. The result is a complex oil–water composition in a high concentration that causes severe hazards to the environment and to aquatic life. In this regard, the current investigation focuses on obtaining hydrophobic cellulose acetate from CBs for use as a filter media. The filter is applied in marine oil spill separation as a win–win industrial ecology technique. Initially, the separated CB residuals were prepared by successive washing. Subsequently, the obtained cellulose acetate fibers were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Furthermore, the new CB-based filters were used in the separation/adsorption of marine oil wastewater spill. Subsequently, a group of experiments were conducted. The results showed that the cleanup efficiency could be up to 99% in terms of chemical oxygen demand (COD). Moreover, the products were recovered by washing with hot water for further use, which showed high removal activity that reached 95% after successive uses. In comparison to commercial oil sorption materials, the results were promising as the RP-C18 cartridge revealed a maximum oil removal of 90%. Such preliminary data on a cellulose acetate filter scheme are a good indicator in the development of an oil spill facility, being a suitable candidate for controlling oil wastewater effluent streams.
