Investigation of the effects of temperature on nitrate removal from drinking water with elemental sulphur based denitrification process

Sulphur based autotrophic denitrification process examined in fixed bed-continuous flow column reactor. In these reactor, nitrate removal efficiencies measured by using bicarbonate (NaHCO3) as source of alkaline. The reactor operated at different temperatures with same hydraulic retention time and flow to determine maximum removal rates. Bacteria samples taken from each column fixed bed-continuous flow reactor to determine nitrate and nitrite removal rates and the temperature differences affecting the gas production examined.
