In the present study, improved moving bed biofilm reactor (MBBR) was applied to enhance the nutrient removal ability of the municipal wastewater.
A total of 18 indigenous bacterial isolates were screened from the sewage sludge sample and nitrate reductase, nitrite reductase and hydroxylamine oxidase was analyzed.
The strains Pseudomonas aeruginosa NU1 and Acinetobacter calcoaceticus K12 produced 0.87 ± 0.05 U/mg and 0.52 ± 0.12 U/mg hydroxylamine oxidase, 1.023 ± 0.062 U/mg and 1.29 ± 0.07 U/mg nitrite reductase, and 0.789 ± 0.031 U/mg and 1.07 ± 0.13 U/mg nitrate reductase.
Nitrogen and phosphate removal improved by the addition of nutrient sources and achieved > 80% removal rate.
pH and temperature of the medium also affected nutrient removal and improved removal was achieved at optimum level (p < 0.05).
MBBR was designed with R1 (aerobic), R2 and R3 (anoxic) reactors.
MBBR reactors removed acceptable level phosphorus removal properties up to 7.2 ± 3.8%, 42.4 ± 4.6%, and 84.2 ± 13.1% in the R1, R2, R3 and R4 reactors, respectively.
Denitrification rate showed linear relationship at increasing concentrations nitrogen content in the reactor and denitrification rate was 1.43 g NO2-N /m2/day at 1.5 g NO2-N /m2/day.
Dehydrogenase activity was assayed in all reactors and maximum amount was detected in the aerobic biofilm reactor.
Based on the present findings, MBBRs and the selected bacterial strains are useful for the degradation domestic wastewater with minimum working area.
