||The removal of eutrophying nutrients from wastewater effluent is of first rank priority in pollution control. One of the major problems is the removal of low concentrations of nitrogen from large volumes of water at an acceptable cost. A pilot-scale, denitrifying plant was built using two types of continuous-flow reactors, a packed column and a suspended growth chamber. Denitrification at three temperature regimes and three dissolved oxygen levels was studied as a function of the methanol:NO3-N ratio. The most efficient ratio was usually found to be between 2:1 and 3:1. Effective denitrification at lower temperatures and high dissolved oxygen content required ratios equal to or slightly greater than 3:1. (Author)
