“…Research has been carried out on the treatment of distilleries wastewater. Various conventional methods have been adopted such as biological flocculation (Zhang et al 2009), nanofiltration (Rai et al 2008), activated carbons (Satyawali and Balakrishnan 2007), bioelectrochemical process (Mohanakrishna et al 2010), ozonation-based process (Sreethawong and Chavadej 2008;Lucas et al 2010;Asaithambi et al 2012), electro-oxidation (Piya-areetham et al 2006;Thakur et al 2009), membrane-based nanofiltration and reverse osmosis (Nataraj et al 2006) and electrocoagulation (Ponselvan et al 2009). However, conventional methods found to be techno-economically non-feasible for the treatment of organic pollutant present in the effluent.…”

The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H 2 O 2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe 2? concentration on Fenton system for the percentage color and chemical oxygen demand removal has been studied. The energy per order was also calculated for the advanced oxidation process. The ozone-photoFenton system has been observed that 100 % color and chemical oxygen demand removal compared with other process studied in the present investigation within 4 h of treatment time. Electrical energy per order has been calculated for all the process and found that ozone-photoFenton shows lesser energy consumption of about 0.01 kWh/m 3 order 1 , for the complete color and chemical oxygen demand removal.

Vinasses are one of the main wastes generated from the mezcal industry in Mexico. Due to their high organic matter content and low pH, vinasses have negative environmental impacts if discharged without any treatment. An alternative treatment of vinasses is their use in microbial fuel cells (MFC) for organic matter removal and electricity production. In this paper, the performance of a MFC using vinasses is analyzed. Different organic matter concentrations in terms of chemical oxygen demand (COD) were tested and compared regarding power density, internal resistance, and voltage production. The results demonstrated that the highest COD tested resulted in a poor MFC performance. When using vinasses in MFC for 10 days, COD of 6000 mg/L generated 80.64 W/m 3 and when using vinasses with a COD of 17 143 mg/L, the power density dropped to 5.13 W/m 3 . Further tests of COD performance in MFC were made with 10 640 and 6760 mg/L for 68 days. It was demonstrated that a COD of 10 604 mg/L only produced 0.61 V, while a COD of 6760 mg/L reached 0.81 V. Regarding the organic matter removal, the highest COD removed (92 %) was obtained when using vinasses with a COD of 10 604 mg/L. By operating the cell with 6000 mg/L, COD removal was 83 % and with 17 143 mg/L, 49 %. To achieve a better MFC performance, the organic matter content in the electrolyte should not exceed 6000 mg/L so that the MFC does not achieve a saturated state that hinders the oxidation mechanisms and thus electricity production and COD removal.Palabras clave: Agave, demanda química de oxígeno, remoción de materia orgánica, producción de electricidad RESUMENLas vinazas son uno de los principales residuos generados por la industria del mezcal en México. Debido a su alto contenido de materia orgánica y bajo pH, las vinazas tienen impactos ambientales negativos si se descargan sin tratamiento alguno. Un tratamiento alternativo de las vinazas es su utilización en celdas de combustible microbianas (CCM) M. López Velarde Santos et al. 522 para la disminución de materia orgánica y la producción de electricidad. En este trabajo se analiza el rendimiento de una CCM operada con vinazas. Diferentes concentraciones de materia orgánica en términos de demanda química de oxígeno (DQO) se utilizaron y compararon con respecto a la densidad de potencia, resistencia interna y la producción de voltaje. Los resultados demostraron que la DQO más alta, dio como resultado un pobre rendimiento de la CCM. Al utilizar las vinazas en la CCM durante 10 días, una DQO de 6000 mg/L generó 80.64 W/m 3 y utilizando las vinazas con una DQO de 17 143 mg/L, la densidad de potencia se redujo a 5.13 W/m 3 . Otras pruebas de rendimiento de la DQO en la CCM se llevaron a cabo por 68 días con DQO de 10 640 y 6760 mg/L. Se demostró que una DQO de 10 604 mg/L sólo produjo 0.61 V, mientras que una DQO de 6760 mg/L alcanzó 0.81 V. En cuanto a la remoción de materia orgánica, la mayor remoción de DQO (92 %) se obtuvo utilizando vinazas en la CCM con 10 604 mg/L de DQO. Utilizando una DQO de 6000 mg/L,...

“…The TDS of the waste water sample has decreased from 800 mg/L to 320 mg/L. The TDS removal rate is affected by many factors, such as salt solution volume, wastewater volume, microbial oxidation and oxygen reduction [48][49][50][51][52][53][54][55][56][57]. …”

“…First, the MFC is a biofilm based system, and the accumulation of biomass mainly resides on the electrode except of occasional biofilm falloff, so the suspended solid is low. Another reason is due to the low cell yield of the anoxic to anaerobic microorganisms in the MFC compared to the activated sludge [58][59][60][61][62][63][64][65][66][67]. …”

Eco system is deteriorating day by day due to Industrial effluents. The effluents are containing toxic chemicals which are inturn polluting ground drinking water and creating new diseases. Treatment methods for these Industrial effluents are becoming more costly. The Present study is aimed and focused at decreasing the toxicity of Industrial waters and the target is Reduction, Recycle and Reuse (RRR) using Microbial Fuel Cell. Microbial Fuel Cell experiments were carried out in batch operations for Appughar waste water using Bakers yeast (saccharomyces cerevisiae organism) in order to increase oxygen levels and decrease toxicity. The parameters studied are design of MFC, NaCl concentration, Agar concentration, fructose dosage, pH, COD, BOD, DO, TSS, TDS, Sulphates, Chlorides and Power generation. The results produced have high oxygen levels and change of pH is appreciable from 7.8 to 7.0. COD, BOD and DO have changed from 1050 to 450 ppm, 560 to 220 ppm and 2.5 to 4.2 ppm.
