Abstract

Disclosed is a method of denitrifying a solution including introducing into the solution an amount of a carbon source within a duration and at a frequency so that indigenous heterotrophic bacteria deplete dissolved oxygen in the solution and decompose oxygen from nitrate in the solution to obtain its combined oxygen. Related apparatuses and compounds also are disclosed.
