ANALYSIS OF WASTEWATER TREATMENT THROUGH MICROBIAL FUEL CELL

Samia Saeed, Muhammad Arsalaan Naveed, Umar Sultan

Introduction: Waste treatment is a problem for all human settlements from small villages to large cities. The traditional method of aeration produces a water which, although clear of solid matter, is rich in nutrients and has devastating effects when discharged into sea or freshwater. Aims and objectives: The basic aim of the study is to analyse the wastewater treatment through microbial fuel cell in Pakistani environment. Material and methods: This descriptive study was conducted in Quaid-i-Azam University, Islamabad during January 2019 to October 2019. All the laboratory-grade biochemical likes urea (Carbamide); malt (Germinated barley); yeast (Saccharomyces Cerevisiae); glucose (Monosaccharide); fructose (Levulose); xylose; ribose (Pentose sugar); protease (Peptidase); amylase (Glycogenase); xylanase (Rhodothermus obamensis) and ligninase (Lignin peroxidases) were used in experiment and purchased. Results: Different industrial wastewater namely Sugar Industry (SI), Brewery Industry (BI), Dairy Industry (DI) and Lather Industry (LI) were used to check the significance of open voltage production. The result presented in Fig. 2(a). From the presentation, it can be seen that the voltage increase with an increase in the number of experiment days at fixed internal resistance 60ohm. Maximum open voltage 1.18 V (current = 19.6 mA and power density = 3.5 mW/m2) showed by sugar industry wastewater than 1.15 V. Conclusion: It is concluded that the application of different strategies to overcome the inherent limitations of the mixed microbial metabolisms and other associated operational problems will increase the practical feasibility of bioenergy generation from wastewater.
