Ultrasound-assisted electrocoagulation process applied to the treatment and reuse of swine slaughterhouse wastewater

Distillery industrial wastewater(DIW) treatment by the combination of sono(US), photo(UV) and electrocoagulation(EC) process

“…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.…”

“…Their findings indicated that when compared to US and EC alone, the US+EC process had much greater COD (99.1%) and color (61.6%) removal efficiencies with a 0.58 kWh m -3 energy consumption. Emerick et al (2020) established that the ECF and ECF/US procedures are viable options for wastewater treatment. Oza et al (2021) demonstrated that integrating US and EC was an effective treatment method for the removal of hazardous contaminants such as arsenic.…”

Treatment of poultry slaughterhouse wastewater using electrocoagulation: a review

“…Electrocoagulation (EC) has recently been used as an efficient alternative to the available PSW treatment methods (Kobya et al 2006b). It is an advanced technology that combines the advantages of conventional coagulation, flotation, oxidation and adsorption processes in one stage (An et al 2017;Emerick et al 2020;Tegladza et al 2021). Organic pollutants of poultry processing effluents are degraded via redox reactions using a 'clean reagent' (Ensano et al 2019).…”

“…EC is also an environmentally benign process, contaminant removal is done with no addition of supplementary chemicals, hence low volumes of sludge and less harmful materials are generated. Lack of additional chemicals also eliminates the detrimental effects of reagents and chemicals usually used in conventional treatment processes (Ensano et al 2019;Emerick et al 2020). It is also characterized by virtue of various benefits including amenability to automation, cost effectiveness, and short treatment time compared to conventional treatment methods (Peralta-Hernández et al 2014;Yildirim et al 2019).…”
