“…However, the high organic load found in wastewater is now recognized as a valuable energy resource rather than mere waste (Twari et al, 2017). The development of microbial fuel cells (MFCs) has indeed emerged as a promising technology to exploit the potential of biodegradable substrates for bioelectricity generation (Chabukdhara et al, 2019). MFCs utilize microorganisms, usually bacteria, to transform organic matter found in biodegradable substrates into electrical energy.…”

Microbial Fuel Cells (MFCs) can simultaneously treat wastewater and generate bioelectricity. This study aimed to optimize operational parameters for treating wastewater from the pharmaceutical industry and harnessing bioelectricity generated from the organic components within the wastewater. The conditions for the bioelectricity generation bioprocess —including time (1-166 days), temperature (25–60°C), pH (4.5–7.5), and additive concentrations (10-50g)—were optimized by the method of Box-Behnken Design (BBD) through the principles of Response Surface Methodology (RSM) incorporated into Design Expert software. The open circuit voltage, current, as well as the physicochemical properties of the wastewater in the MFC were closely monitored. The initial Chemical oxygen demand (COD) and Biochemical oxygen demand (BOD) were 1025 and 1346.17 mg/L. The prominent microorganism in both wastewater and fruit waste samples were Esherichia coli, Staphylococcus species, and Salmonella. At optimized conditions (87 days, 42.5oC, pH of 7.5, and 30 g of additives) the maximum voltage of 895 mV and current of 264 mA were obtained. The result illustrated that fruit waste significantly influenced the generation of bioelectricity as well as the reduction of COD and BOD. The maximum power density generated from pharmaceutical wastewater with no fruit waste was 736.13 mW/m2 while the maximum power densities obtained with the addition of pineapple, orange, mango and combination of all the fruit wastes to the pharmaceutical wastewater were 1610.29, 1355, 759.08 and 2168 mW/m2, respectively. These results illustrate the optimum process conditions which can be explored for bioelectricity generation as well as bio-treatment of industrial wastewater.

“…Advanced technologies such as oxidation, photocatalytic degradation, bioreactor filtration, Fenton reactor, and UV disinfection have been investigated for WW treatment [28][29][30][31]. However, although some of these technologies are showing promising results in the reduction of drugs of abuse and their metabolites, they are expensive and their large-scale application is not economically or sustainably viable [3,32,33].…”

METHs are drugs that enter wastewater through the feces and urine of users. Conventional wastewater treatment plants are not capable of removing this type of emerging contaminant, but, in recent years, techniques have been developed to abate drugs of abuse. The present investigation focused on obtaining the technique that keeps the best balance between the comparison criteria considered: efficiency; costs; development stage; and waste generation. That is why a bibliographic review was carried out in the scientific databases of the last eight years, concluding that the six most popular techniques are: SBR, Fenton reaction, mixed-flow bioreactor, ozonation, photocatalysis, and UV disinfection. Subsequently, the Saaty and Modified Saaty methods were applied, obtaining a polynomial equation containing the four comparison criteria for the evaluation of the techniques. It is concluded that the UV disinfection method is the one with the best relationship between the analyzed criteria, reaching a score of 0.8591/1, followed by the Fenton method with a score of 0.6925/1. This research work constitutes a practical and easy-to-use tool for decision-makers, since it allows finding an optimal treatment for the abatement of METHs.
