Removal Of Pathogenic Bacteria In Hospital Waste Water Using Chitosan

Elimination of pathogenic microorganism from waste water is a matter of concern in last few decades. Untreated waste water discharged from hospitals, produce health hazards to the living organisms. In this study, chitosan was used to eliminate pathogenic bacteria from hospital waste water. Uncountable colonies of E.coli (more than 300 colonies) and countable colonies (22 colonies) of Samonella were observed in the hospital waste water. After the antibacterial treatment period of 24 hours, pour plate method illustrated that, the E. coli, S. bongori and S. enterica were eliminated from the hospital waste water.
