“…The electrooxidation process is used in many industrial wastewater treatments with high organic matter concentration such as reactive dye (Kahraman & Şimşek, 2020; Lu et al, 2021; Yao et al, 2021), tannery (Caliari et al, 2019), coking wastewater (Zhang et al, 2020), domestic wastewater (Clematis & Panizza, 2021; Mwangi et al, 2021), slaughterhouse wastewater (Özturk et al, 2021), dairy (Turan, 2021), petroleum wastewater (Abou‐Taleb et al, 2021), and endocrine disruptor (Frontistis et al, 2017; Periyasamy & Muthuchamy, 2018). Moreover, recent work by Hajalifard et al (2023) highlights the integration of advanced oxidation processes (AOPs) with electrocoagulation (EC) methods for water and waste water treatment, particularly emphasizing the removal of emerging contaminants and showed potentials for reducing energy consumption and sludge production.…”

This study addresses the pressing issue of bilge water pollution from ships, a highly oily and hazardous wastewater source. The research employs the electrooxidation/flotation process, known for its effectiveness in organic matter removal. Key parameters, such as initial pH, current density and flow rate, were investigated for their impact on the removal of chemical oxygen demand (COD) and oil‐grease (OG) from bilge water. Initial pH showed minimal effects on COD and OG removal, while current density significantly enhanced removal efficiency by influencing anodic electrochemical reactions. Conversely, higher flow rates reduced residence time and lowered removal efficiency. Optimal conditions, with a current density of 10 mA/cm2, pH 7.5 and a flow rate of 20 ml/min, achieved impressive results, removing approximately 80% of COD and 99% of OG from bilge water. These findings highlight the potential of this method for effective bilge water purification.

Groundwater and surface water have been the primary sources of our public water supply around the world. However, rapid population and economic growth, as well as global climate change, are posing major threats to the quality and quantity of these water resources. Treated wastewater (reclaimed water) and stormwater are becoming more important water resources. Use/reuse of these unconventional water resources can enable a truly sustainable, closed-loop, circular water system. However, these two sources are not usually mixed with each other. In this study, we propose the use of combined excess urban stormwater and reclaimed water as a source of potable water supply. One of the most pronounced benefits of this proposed scheme is the possible elimination of costly and energy-intensive processes like reverse osmosis. Reclaimed water tends to have high concentrations of dissolved solids (>500 mg/L) and nitrate-N (>10 mg/L), which can be lowered by blending with stormwater or rainwater. Despite technical and engineering challenges, this approach can benefit various communities—small, medium, large, upstream, downstream, urban, and rural—in diverse climates. Our study suggests that this new holistic approach is feasible, enabling the combined water to be directly used as a sustainable drinking water source.
