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.

Compound for denitrifying a solution comprising:
- a backbone selected from a polyol, a simple sugar and combinations thereof;
- and
- a substituent selected from:
- a low molecular weight organic acid radical attached with ester linkages, an alkyl group from a simple alcohol attached with ether linkages and combinations thereof;
- wherein said polyol is selected from ethylene glycol, propanediol, diethylene glycol, triethylene glycol, dipropylene glycol, tripropylene glycol, dibutyleneglycol, and combinations thereof.
