“…These products are usually much more effective than added chemicals and are capable of destabilizing colloidal suspensions and emulsions. Nidheesh et al [49] used electrocoagulation process with iron, aluminum, and steel electrodes to treat oil refinery wastewater, and the results showed that this process could be a suitable method to reduce sulfate and COD concentration from oil refinery wastewater. Also, in the research where Asselin et al used electrocoagulation process with aluminum and steel electrodes to treat the oil effluents of ships, it was found that the optimal state was obtained with steel electrodes, and 93% removal for BOD, more than 95% for oil removal, and about 68% for COD removal are achieved in optimal conditions [41].…”

Petroleum hydrocarbons in refinery wastewater are considered the main cause of pollution. Wastewater from oil refineries contains large amounts of oil and fat in the form of suspended particles, light and heavy hydrocarbons, phenol, and other dissolved organic substances, which cause environmental pollution if they are discharged into the environment without treatment. Usually, conventional methods of treating petroleum wastes have a lot of costs; due to the existence of sufficient area for the construction of solar distillation ponds and suitable sunlight, as well as a large number of sunny days near the equator, the solar distillation method can be used. Membrane bioreactors based on biological decomposition and biological transformation of oils and waste oil materials have provided new solutions for the biological treatment of these wastewater. In addition to these methods, Fenton’s advanced oxidation methods, electrochemical coagulation method, and membrane filtration method are mentioned in this chapter.

“…Such microplastics are considered as pollutants with potential environmental risks in both aquatic and terrestrial ecosystems. In addition to their direct acute biotoxicity [4], microplastics can be enriched with a number of organic pollutants, thus creating ecological risks [5]. Microplastics find their way through plastic manufacturing, household waste, wear and tear of plastic products, decomposition of plastic waste, and ultimately in air, soil and water [6].…”

Owing to water scarcity, groundwater quality has become an important constraint on sustainable regional development, especially in coastal areas. Coastal groundwater is subject to natural conditions and intense human activities, and the evolution of water quality is extremely complex, with the possibility of seawater intrusion into the groundwater, leading to the salinisation of freshwater aquifers. At present, the commonly used methods for removing groundwater pollution include coagulation, adsorption, biological method, membrane technology, etc., among which the coagulation method is more commonly used. At present, three-dimensional electrode electrochemical technology is widely used in high salinity organic wastewater and many organic wastewaters, but there are few studies related to microplastic removal by three-dimensional electrode electrochemical technology using metallic aluminium particles as particle electrodes. The treatment of microplastics in coastal groundwater is a relatively novel issue, and with the increasing application of three-dimensional electrochemical technology in the study of desalination, the three-dimensional electrode electrochemical technology will be promising due to the high salinity of coastal groundwater, the increasingly serious pollution of microplastics, and the fluctuation of water quality and quantity.

“…In the meantime, electroseparation and electroconversion processes have been proposed in wastewater treatment [17,18]. Electrosorption, capacitive deionization (CDI) and electrocoagulation could improve the separation of both inorganic and organic compounds compared to the physical (adsorption) or chemical (coagulation-flocculation) equivalent techniques [19][20][21][22]. Additionally, electroconversion technologies, such as electro-Fenton, anodic oxidation and the related systems, highlighted very high removal rates and yields of the organic pollutants, even the most recalcitrant ones [23][24][25][26].…”
