“…Many water treatment processes require significant energy inputs for pumping, mixing, aeration, and heating. Energy-intensive treatment methods, such as membrane filtration and desalination, contribute to greenhouse gas emissions and environmental degradation (Grzegorzek et al, 2023). The use of chemicals in water treatment can result in the generation of harmful byproducts and residual contaminants.…”

Water treatment processes in chemical engineering play a critical role in addressing environmental challenges and ensuring the sustainability of water resources. This paper examines simulation-driven strategies aimed at enhancing water treatment processes within the domain of chemical engineering. By leveraging advanced simulation techniques and methodologies, engineers can optimize the design, operation, and performance of water treatment systems, thereby mitigating environmental impacts and improving overall efficiency. The review highlights the importance of addressing environmental challenges through innovative approaches in water treatment processes. It underscores the role of simulation-driven strategies in chemical engineering to achieve sustainable solutions for water management. Through a comprehensive review of simulation techniques and case studies, this paper elucidates how simulation-driven approaches can enhance the effectiveness and sustainability of water treatment processes. Furthermore, the review emphasizes the interdisciplinary nature of this research, bridging chemical engineering principles with environmental science and technology. By integrating simulation tools with knowledge of water chemistry, fluid dynamics, and process engineering, engineers can develop robust strategies for optimizing water treatment processes while minimizing environmental footprints. Key topics covered include the application of computational fluid dynamics (CFD), process simulation software, and advanced modeling techniques in the analysis and design of water treatment systems. Case studies illustrating the successful implementation of simulation-driven strategies in various water treatment applications are presented to provide practical insights and demonstrate the potential benefits. Overall, this paper underscores the pivotal role of simulation-driven strategies in advancing water treatment processes in chemical engineering. It advocates for the adoption of innovative approaches to address environmental challenges and promote sustainability in water management practices within the oil and gas industry and other sectors reliant on chemical engineering processes.

“…Currently, various water treatment methods, including ion exchange, reverse osmosis, membrane separation, coagulation and flocculation, chemical sedimentation, and adsorption, have been employed for the removal of heavy metals (Chen et al, 2020;Qasem et al, 2021;Saha et al, 2022;Grzegorzek et al, 2023;Yang, 2024). Therefore, there is a need for exploring new alternatives and advancements in heavy metal treatment (Mohammed et al, 2016;Sallam et al, 2017;Yousefi et al, 2019;Sasidharan et al, 2022).…”

The removal of hazardous metal ions from polluted water is a crucial process aimed at enhancing water quality. In this study, we conducted a dynamic adsorption investigation utilizing natural green clay for the removal of hexavalent chromium from aqueous solutions. The material underwent characterization through various techniques, including fluorescence spectrometry (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and nitrogen-physisorption (BET). Column tests of green clay material and sand mixtures were performed to evaluate sorption in dynamic systems. Adsorption conditions were examined by varying the initial Cr6+ concentration, flow rate and column height. The maximum purification was achieved at a concentration of 50 mg/L, a flow rate of 3mL/min and a bed height of 12 cm. The mathematical models of Bohart-Adams, Thomas, and Yoon-Nelson were employed to analyze experimental data and predict breakthrough curves in continuous adsorption. Through comparison of R2 values, it was determined that the Yoon-Nelson and Thomas diffusion models effectively capture and accurately describe the experimental data. The results obtained indicate a potential expansion of fixed-bed adsorption for the heavy metals treatment in industrial-scale wastewater. Additionally, the natural green clay material exhibited remarkable reusability and showed promising characteristics for various environmental and industrial applications.

“…Various forms of flotation are used in separation processes, including induced air flotation (IAF), dissolved air flotation (DAF), Jet, Ion flotation, and column flotation. Notably, DAF has superior separation efficiency in wastewater treatment but is expensive due to high water saturation costs [9]. For this study, column flotation was explored as it is relatively cheap.…”

The poultry industry generates significant volumes of slaughterhouse wastewater, laden with numerous pollutants, thus requiring pretreatment prior to discharge. However, new technologies must be used to re-engineer the existing wastewater treatment equipment and incorporate new designs to improve the treatment processes or system performance. In this study, three variables, i.e., diffuser design, bioflocculant form, and flow rate, were evaluated to determine their effect on the performance of a bioflocculant-supported column flotation (BioCF) system. It was found that bioflocculants influenced diffuser performance with limited impact when the feed flow rate was varied, i.e., 3D-printed air diffusers and cell-free flocculants imparted high BioCF performance when compared to moulded diffusers and cell-bound flocculants. Notably, the combination of 3D-printed air diffusers and cell-free flocculants resulted in relatively high pollutant removal (81.23% COD, 94.44% TSS, 97.77% protein, and 90.38% turbidity reduction). The study lays a foundation for exploring 3D-printed air diffusers, a relatively new technology in conjunction with microbial flocculants usage that are regarded as eco-friendly for application in industry to enhance the performance of column flotation systems.
