Comparative Analysis Of The Microbiological And Physicochemical Characteristics Of Grey water Sources In Umudike, Abia State, Nigeria.:- Mgbeokwere, Ebubechi U

ABSTRACT

The Comparative analysis of the Microbiological and physico chemical characteristics of greywater samples in Umuahia were carried out. The total heterotrophic plate count ranged from 8.1x10° to 1.11x10cfu/ml, Salmonella-Shigella count ranged from 3.9x10° to 5.0x10cfu/ml, Escherichia coli count ranged from 2.0x10° to 3.3x10cfu/ml, Enterobacter aerogenes count ranged from 3.0x10° to 3.9x10cfu/ml, the fungal count ranged from 1.5x10° to 4.2x 10cfu/ml while the coliform count ranged from 2100MPN/100ml to ll000MPN/IO0ml. The microorganisms isolated and their percentage occurence were Enterobacter aerogenes (23.8%), Proteus species (9.52%), Escherichia coli (28.57%), Pseudomonas aeroginosa (19.05%), Salmonella species (14.29%), Staphylococcus aureus (4.76%), Rhizopus species (20%), Penicillium species (20%), Aspergillus species (40%), Trichoderma species (20%). The results showed that the effluent samples were contaminated heavily with known pathogenic microorganisms and should therefore be treated before reuse. This study suggests the need for greywater to be treated properly before reuse
