ABSTRACT:
An improved multi-stage treatment system for biological denitrification of and suspended solids removal from water includes a biological reactor containing rigid media supporting denitrifying bacterial growths, an aeration chamber and an automatic backwash filter. In use, methanol or other carbon source containing influent water flows into the reactor beneath the rigid media and upwardly in contact with said bacterial growths to cause nitrates and nitrites contained therein to be converted into nitrogen. The denitrified water is then aerated in the aeration chamber and subsequently filtered by downward flow through the automatic backwash filter.
