Nutrient compounds such as ammoniacal nitrogen (NH4-N), nitrite and nitrate, of ten present in different types of waters and wastewaters, can find their way to lakes, rivers and drinking water reservoirs. Wastewater NH4-N is becoming more important in the alleviation of environmental problems including eutrophication, corrosion and fouling. A pilot plant was designed to study the removal of ammoniacal nitrogen using biological system. The nitrification process was carried out in a sequential batch reactor and removal of nitrate from the system generated during the oxidation of ammoniacal nitrogen was carried out in a photobioreactor using algae. On average 95% ammoniacal nitrogen removal was achieved by the sequential batch reactor and 98% nitrate removal was achieved using photobioreactor.
