A Two Bioreactor Treating Brewery Wastewater

Abstract:

Article Preview

A two stage bioreactor was employed in bioremediation study of laboratory simulated brewery wastewater. Two weeks anaerobic dark incubation of the artificial brewery wastewater without external seeding resulted in an effluent with 138mgl-1VFA; the chemical oxygen demand decreased from 10,000 to 7,814mgl-1 total nitrogen and total phosphorus recorded 18.63 and 18.95% reductions. Further treatment of the anaerobic effluent with a photobacterium named Z08, reduced both the pollutants (COD, TN, TP) and high energy molecules (VFA) significantly by 36.8, 67.5, 27.0, and 60% respectively. Addition of 200mgl-1 NH2-CO-NH2 to the effluent yielded the best result, reducing COD, TN, TP and VFA by 67.5, 68.9, 34.2 and 82%.
