Abstract
In the denitrification process, the percentage of biodegradable Carbon can be a limiting factor for Nitrate removal. The addition of a Carbon source may improve the denitrification process. This study arose from the need of adding a Carbon source in the anoxic tank of a wastewater treatment plant (WWTP) of an anaerobic digesting unit of Municipal Solid Wastes (MSW). The purpose was to evaluate the efficiency of using the effluent from the hydrolysis tank and compare it with Methanol. The results showed that the Nitrate removal was high in all tests (176 mgN-NO3/L in noC; 282 mgN-NO3/L in MeC; 185 mgN-NO3/L in HyC), but the volumetric removal rate was different (88 mgN-NO3/(L.d) in noC; 262 mgN-NO3/(L.d) in MeC; 185 mgN-NO3/(L.d) in HyC). The specific denitrification rate of different tests showed that the hydrolysis effluent improved the rate of Nitrate removal.
