The complex wastewater was characterized for physicochemical parameter. Five microbial species were isolated from different potential sources and their degradation potential was evaluated individually and in the form of consortia. Accordingly, lab studies were carried out in biological treatment system using aerobic microbial consortia along with individual microbial species in separate reactors. Temperature and pH of reaction tank was continuously monitored during study period. Other vital physicochemical parameters viz. COD, BOD, TSS and TDS were evaluated during 72 hours of study. The microbial consortia comprise of Pseudomonas spp., Actinomycetes spp., Bacillus spp., Streptomyces spp. and Staphylococcus spp. was able to trim down the physicochemical parameters of complex wastewater. The consortia demonstrated high COD and BOD reduction up to 90.17% and 94.02% respectively, compared to individual microbial species ranging from 42.11-59.76% for COD and 58.55-77.31% in case of BOD.
