Denitrification studies of sewage water for the percentage conversion of nitrate by using obligate aerobes derived from fruit waste

Seshagiri Murikipudi, Meena Vangalapati

Denitrification process is used for the treatment of sewage water. In the present study, optimization of the parameters like biomass concentration, pH, time and the percentage conversion of nitrate by using obligate aerobes are studied. By varying the parameters in the range of 0.5 to 5.0%(w/ v), 6.0 to 10.0, 0 to 12 days for biomass concentration, pH, time and conversion of nitrate respectively. The optimized parameters at which the maximumdenitrification is noticed and found to be biomass concentration of 1%(w/v), pH9.0, time 8 days andmore than 80%(nearly 83%) conversion of nitrates is noticed fromthe experimental work.
