“…At a 0.10 m salt bridge length and 10% agar concentration, the efficiency parameters were PD max of 1.0 W m −2 , CD max of 1219.69 mA m −2 , power of 14.27 mW, OCV max of 886.34 mV, current of 16.10 mA, and COD of 86.3 %. In another study using a similar configuration, the COD removal rate was 92.2%, BOD removal was 88.02%, TDS removal was 76.3%, and OCV max was 644mV [ 248 ]. A double-chamber MFC devoid of a membrane generated more current using copper electrodes than stainless steel electrodes [ 248 ].…”

“…Both MFCs and MECs are alleged to be self-sustainable podiums for recuperating energy from waste because they can break down the organic matter present in dairy wastewater along with an additional production of electricity or clean fuel such as H 2 [7,164]. Similarly, MCCs that employ algal cells assist in the recycling of CO 2 into biomass, resulting in the sequestration of CO 2 [165].…”

“…This dairy effluent comprises proteins, fats, milk carbohydrates, nutrients, and other cleaning solutions that contribute to the pollution load. Usually, dairy wastewater is found to have characteristics such as a chemical oxygen demand (COD) that varies from 80,000 to 90,000 mg/L and a biochemical oxygen demand (BOD) of around 50,000 to 45,000 mg/L, high total suspended solids (TSS) of about 25,000 to 45,000 mg/L, and a varying pH that ranges between 4 and 10 [5][6][7]. The existing wastewater management machinery is inefficient for eliminating all these contaminants at one time; as a result, partially treated water is discharged into the environment.…”

A milk-processing plant was drafted as a distinctive staple industry amid the diverse field of industries. Dairy products such as yogurt, cheese, milk powder, etc., consume a huge amount of water not only for product processing, but also for sanitary purposes and for washing dairy-based industrial gear. Henceforth, the wastewater released after the above-mentioned operations comprises a greater concentration of nutrients, chemical oxygen demand, biochemical oxygen demand, total suspended solids, and organic and inorganic contents that can pose severe ecological issues if not managed effectively. The well-known processes such as coagulation–flocculation, membrane technologies, electrocoagulation, and other biological processes such as use of a sequencing batch reactor, upflow sludge anaerobic blanket reactor, etc., that are exploited for the treatment of dairy effluent are extremely energy-exhaustive and acquire huge costs in terms of fabrication and maintenance. In addition, these processes are not competent in totally removing various contaminants that exist in dairy effluent. Accordingly, to decrease the energy need, microbial electrochemical technologies (METs) can be effectively employed, thereby also compensating the purification charges by converting the chemical energy present in impurities into bioelectricity and value-added products. Based on this, the current review article illuminates the application of diverse METs as a suitable substitute for traditional technology for treating dairy wastewater. Additionally, several hindrances on the way to real-world application and techno-economic assessment of revolutionary METs are also deliberated.

“…From the above experimental output, we can say that wastewater from the dairy industry contains a higher amount of lactose related to synthetic wastewater, as the output voltage is higher with real dairy wastewater. So, scientists and scholars need to put more attention towards the application of wastewater from organic matter to attain products with added value [41].…”

To investigate the performance of microbial fuel cell (MFC) with a single-chamber membrane, Pseudomonas aeruginosa is used as a bio catalyst for various synthetic wastewaters rich in carbohydrate and is compared with real dairy wastewater in this experiment. Therefore, the choice of appropriate carbon, nitrogen, NaCl, inoculum content, temperature, and pH process parameters are used for preparing synthetic wastewater was agreed upon by one-variable-at-a time approach. Maximum levels of voltage generation attained from the synthetic wastewater was 485 mV when supplemented with 1.5 % of lactose as a source of carbon, 0.3 % of ammonium chloride as a decent nitrogen source, 0.03 % of NaCl, inoculum concentration of 3 %, the temperature at 37 oC and pH 7. On the other hand, the maximum voltage attained with real dairy wastewater was 561 mV with high chemical oxygen demand (COD) value of 801 mg l-1. The maximum power density obtained from dairy wastewater was 73.54 mW m-2. Thus, High voltage achieved for MFC operating with real dairy wastewater suggests that it can be used not only for the industrial application to generate more renewable power, but also for the wastewater treatment carried out at the same time.
