“…The major one, OTU_1 had an abundance of up to 35% in the samples from the culture medium, but could not be affiliated up to the species level. Different species of this aerobic genus have already been identified in wastewater treatment plants (Liu et al, 2017;Chen et al, 2019b), including BESs (Sathishkumar et al, 2019). The Acinetobacter genus has already been identified in O 2 -reducing bidirectional biofilms (Blanchet et al, 2014;Yun et al, 2018) with, in these cases too, a higher abundance in the culture medium.…”

In anode operation, current density up to 6.4 A.m − 2 were produced in real wastewater.• Bioanodes formed in open-to-air reactor gave higher O 2 -reduction current when aerated.• Gammaproteobacteria, Bacteroidia and Clostridia were the three dominant classes.• Clear distinction between the planktonic and sessile microbial populations.• Biofilm microbial population mixed both aerobic and anaerobic electroactive species.

“…The modern technologies can be based on the individual oxidation approaches involving cavitation or in general the advanced oxidation processes (AOPs) comprising of ozonation [8] , hypochlorite [9] , hydrogen peroxide (H 2 O 2 ) [10] , UV [11] , Fenton oxidation [12] , etc. or various combination approaches such as photo-Fenton oxidation [13] , photocatalysis [14] , [15] , electrochemical process [16] , peroxone [17] etc. The main governing mechanism is the generation of highly reactive species (HO • , HOO • ) [18] , [19] , [20] as well as the direct attack of oxidants when chemical oxidants are used.…”

Highlights Critical analysis of the hybrid processes involving ultrasound, Fenton and ozone. Guidelines for optimum operating conditions provided for maximum benefits. Original study on treatment of two real industrial effluents. US-Fenton approach followed by lime treatment established as the best approach. Use of ozone does not add much benefits to US-Fenton treatment process.

“…These methods are of significant interest as they combine three parallel processes, namely electrocoagulation, electrooxidation and electroflotation [ 11 , 12 , 13 ]. Numerous scientific studies have reported total decolorization of wastewaters containing azo dyes by electrochemical means, in the order of 71–99% [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. However, despite the high efficiency of such dc-powered systems, they still suffer from excessive power consumption.…”

Traditional wastewater purification processes are based on a combination of physical, chemical, and biological methods; however, typical electrochemical techniques for removing pollutants require large amounts of electrical energy. In this study, we report on a process of wastewater purification, through continuous anodic dissolution of iron anode for aerated Cu/Fe galvanic cell in synthetic Na2SO4 wastewater solution. Electrochemical experiments were conducted by means of a laboratory size electrolyzer, where electrocoagulation along with electrooxidation phenomena were examined for wastewater containing Acid Mixture dye. The above was visualized through the employment of electrochemical (cyclic voltammetry and ac impedance spectroscopy techniques) along with instrumental spectroscopy analyses.
