Two types of fixed-bed and fluidized-bed biofilm reactors, equipped with expanded clay granular filler, with a particle size fraction of 2-5 mm were used. The nitrite and nitrate concentrations in the inflow and outflow of the two bioreactors were analytically determined. Based on the obtained concentration values, the denitrification rates were calculated, ranging between 1275÷1387 g NO 3-N/m3/day in the case of the fixed bioreactor and between 3390÷3867 g NO 3-N/m3/day in the case of the fluidized bed bioreactor. |
