Electrocoagulation (EC) is a process used by supply of electric current with sacrificial electrodes for the removal of pollutant from wastewater. The study was experimentally investigated taking into account various factors such as pH (3-7.5), current (0.03-0.09 A), distance between the electrodes (1-2 cm), electrolytic concentration (1-3 g/L), and electrolysis time (20-60 min) which is impact on the % removal efficiency of color, chemical oxygen demand (COD), turbidity and determination of energy consumption used for aluminum (Al) electrode used. The surface response design process based on the central composite design (CCD) has been used to optimize different operational parameters for treatment of hospital wastewater using EC process. The % color, COD and turbidity removal, and energy consumption under different conditions were predicted with the aid of a quadratic model, as were the significance and their interaction with independent variables assessed by analysis of variance (ANOVA). The optimal conditions were obtained through mathematical and statistical methods to reach maximum % color, COD, and turbidity removal with minimum energy consumption. The results showed that the maximum removal of color (92.30%), COD (95.28%), and turbidity (83.33%) were achieved at pH-7.5, current-0.09A, electrolytic concentration-3g/L, distance between electrodes-2 cm and reaction time 60 min. This means that, the process of EC can remove pollutants from various types of wastewaters and industrial effluent under the various operating parameters.

In order to solve the shortcomings of a single flocculant, the inorganic-organic hybrid flocculant SiO-CTS-DMDACC was successfully prepared by grafting copolymerization of chitosan (CTS), dimethyl diallyl ammonium chloride (DMDACC), and silicon dioxide (SiO). The performance of SiO-CTS-DMDACC in treating papermaking wastewater was investigated, and the mechanism of the flocculation process was analyzed. The results showed that the crystallinity of chitosan was reduced due to the introduction of DMDACC and SiO.

However, monitoring the presence of bacterial concentrations in real time at each stage of the WRRF is challenging as it requires taking and processing water samples offline. Although few studies have been proposed to predict bacterial concentrations using data-driven models, generalizing these models to unseen data from different WRRFs remains challenging.

In this research, a sustainable blue-green infrastructure (BGI) was developed to efficiently remove contaminants from stormwater through a combined use of modified porous asphalt (PA) and microalgae cultivation to provide a potential drinking water (DW) source. According to the results, the modified PA with powder activated carbon (PAC) could successfully reduce the level of total suspended solids (TSS), turbidity, polycyclic aromatic hydrocarbons (PAHs), oil and grease to below the DW standards but failed to efficiently remove some heavy metals (HMs) and nutrient pollutants. The results revealed that the treated stormwater was an appropriate medium for microalgae cultivation.

The environmental burden of tannery wastewater, characterized by high levels of total dissolved solids (TDS) and other contaminants, presents a significant challenge for sustainable water management. This study addresses this issue by developing a novel polyvinyl alcohol (PVA) and polyvinyl chloride (PVC) composite membrane optimized for efficient TDS removal from tannery effluent. The membrane was fabricated using a solution casting technique, with glutaraldehyde employed as a crosslinking agent to enhance mechanical properties and stability.
