ABSTRACT:
Disclosed is an apparatus for denitrifying a solution that includes a denitrification tank configured to receive a portion of the solution for a period of time. Controlling an amount, duration and frequency of introduction of polyethylene glycol into the solution promotes indigenous heterotrophic bacteria depleting dissolved oxygen in the solution and obtaining oxygen from nitrate in the solution.
