This study evaluated the efficacy of activated carbon from rice husk, corn cob and coconut husk wastes in the reduction of microbial properties of grey water samples harvested from students’ hostels. Microscopic characterization, enumerations and identification of microbial isolates were carried out to determine the microbial community before and after the treatment with activated carbon.  Staphylococcus sp, Micrococcus sp, Bacillus sp, Salmonella sp, Saccharomyces sp and Penicillium sp were observed to be present in the grey water. Before treatment, Total Heterotrophic Count (THC) was 1.2 x 1011cfu/ml, Total Coliform Count (TCC), 6.4 x 106cfu/ml and Total Fungi Count (TFC) 2.2 x 1010cfu/ml. THC after the treatment ranged from 1.69 x 109 - 7.6 x 1010cfu/ml; TCC, 2.2 x 105 - 7.3 x 108cfu/ml and TFC 1.0 x 108 - 1.2 x 109cfu/ml. Reduction in the microbial load after treatment revealed that activated carbons from rice husk, corn cob and coconut husk can be used singly or in combined states for the treatment of wastewater.
