Nitrate removal from groundwater using an activated sludge as a source of bacteria
In this study, the denitrification of nitrate-contaminated groundwater by the heterotrophic denitrification (HD) method was studied to produce drinking water.Preliminary tests were carried out in a denitrification reactor, consisting of an opaque PVC column filled with a plastic packing, and fed with a synthetic solution based on glycerol, in which
