“…The current density is an important factor in the hybrid EC process for the treatment of industrial effluent (Sandhwar and Prasad 2018;Mehralian et al 2021;Moradi et al 2021). The current density was varied between 0.07 and 0.20 A dm -2 in this investigation for the US+UV+EC system utilizing the DIW, and the findings are depicted in Fig.…”

“…Numerous research studies have demonstrated that EC works cohesively with other treatment modalities, including ozone (O3) assisted EC (He et al 2007;Das et al 2021;Mehralian et al 2021), EC/Adsorption, EC/Chemical coagulation, EC/Magnetic field, EC/reverse osmosis (Al-Qodah et al 2020), US-EC (Emerick et al 2020;Moradi et al 2021), alternating current EC (Alimohammadi et al 2019;Payami Shabestar et al 2021), peroxi-EC (Sandhwar and Prasad 2018), photo-EC (Farhadi et al 2012;Asaithambi et al 2016;Moradi and Moussavi 2019), aerated EC (Akansha et al 2020), EC-nanofiltration and membrane filtration (Tavangar et al 2019;Gönder et al 2020;Ucevli and Kaya 2021) for the elimination of contaminants from industrial effluent and wastewater. Farhadi et al (2012) compared the various processes for removal of COD from pharmaceutical wastewater.…”

“…However, when ozonation and electrocoagulation were combined, a relatively good outcome was obtained. Mehralian et al [154] examined the removal of COD from real cardboard effluent using the EC/O 3 process with the Box-Behnken Design (BBD). eir findings indicated that the EC/O 3 procedure might be used to rapidly and effectively remove colour and COD from wastewater.…”

Nowadays, increased human activity, industrialization, and urbanization result in the production of enormous quantities of wastewater. Generally, physicochemical and biological methods are employed to treat industrial effluent and wastewater and have demonstrated high efficacy in removing pollutants. However, some industrial effluent and wastewater contain contaminants that are extremely difficult to remove using standard physicochemical and biological processes. Previously, electrochemical and hybrid advanced oxidation processes (AOP) were considered a viable and promising alternative for achieving an adequate effluent treatment strategy in such instances. These processes rely on the production of hydroxyl radicals, which are highly reactive oxidants that efficiently break down contaminants found in wastewater and industrial effluent. This review focuses on the removal of contaminants from industrial effluents and wastewater through the integration of electrochemical and advanced oxidation techniques. These processes include electrooxidation, electrocoagulation/electroflocculation, electroflotation, photo-Fenton, ozone-photo-Fenton, sono-photo-Fenton, photo-electro-Fenton, ozone/electrocoagulation, sono-electrocoagulation, and peroxi/photo/electrocoagulation. The data acquired from over 150 published articles, most of which were laboratory experiments, demonstrated that the hybrid process is more effective in removing contaminants from industrial effluent and wastewater than standalone processes.

“…Process variables for the treatment of wastewater such as slaughterhouse [ 12 , 13 ], metal plating [ 14 ], paper mill [ 15 ], automobile [ 16 ], textile [ 17 ] and metal working [ 18 ] by electrocoagulation have been optimized using the response surface methodology. There are several studies in the literature that examine the treatment of real cardboard wastewater with electrocoagulation [ 1 , 19 , 20 ]. In one of these studies, optimization was made by response surface method for electrocoagulation/ozone hybrid method, but COD was selected as the only response and energy consumption was not optimized.…”

The electrocoagulation method using stainless steel anodes was applied to a corrugated cardboard box manufacturing plant’s wastewater with high COD content. The effects of current density, processing time and stirring speed on response functions were studied using the Response Surface Methodology (RSM). The removal efficiency of chemical oxygen demand (COD) and energy consumption were selected as response functions. The Central Composite Design (CCD) was chosen to explain the single and combined effects of independent variables on response functions. The COD concentration of the real industrial wastewater used in the experiments was 9130 mg L −1 . The maximum COD removal efficiency of 91.6% is obtained with 19.78 Wh g −1 energy consumption. Current density and treatment time were effective parameters for both COD removal and energy consumption. Optimization for maximum COD removal with minimum energy consumption showed 80.9% of COD removal with 6.7 Wh g −1 of energy consumption at 15 mA cm −2 , 700 rpm, and 28 min treatment time. The variables are optimized with a few experiments using the response surface method. Graphical abstract
