Denitrification system for nitrified wastewater or nitrified water

A method for denitrification of nitrified wastewater or nitrified water comprising the steps of:

• providing a series of interconnected tanks underground, each tank having an inlet, an outlet, and a conduit connecting said outlet of a preceding tank to said inlet of a succeeding tank;
• providing to an inlet of a mixing tank of said series of interconnected tanks, said nitrified wastewater or nitrified water having nitrates and nitrites;
• mixing a detergent with said nitrified wastewater or said nitrified water in said mixing tank to enhance the reduction of said nitrates and nitrites to gaseous nitrogen dioxide (N2O) and nitrogen (N2) in the resulting effluent;
• controlling the amount of detergent introduced into said mixing tank in accordance with the flow volume of said nitrified wastewater or said nitrified water entering said mixing tank;
• heating said effluent to accelerate said denitrification;
• feeding effluent from said mixing tank to at least one detention tank in said series of interconnected tanks for establishing a detention period of said effluent;
• connecting a last one of said series of interconnected tanks to a pumping chamber;
• and
• pumping said effluent from said pumping chamber to a filter for further reducing bacteria populations including nitrogen in said effluent exiting from said filter.

A denitrification system for treating nitrified wastewater or nitrified water comprising:

• a series of interconnected tanks positioned underground, each tank having an inlet and an outlet and a conduit connecting an outlet of a preceding tank to an inlet of a succeeding tank;
• a first tank of said series of interconnected tanks receives at said inlet said wastewater or nitrified water having nitrates and nitrites;
• means for providing a detergent to said first tank, said detergent enhancing the reduction of said nitrates and nitrites to gaseous nitrogen dioxide (N2O) and nitrogen (N2);
• means for controlling the amount of detergent introduced into said first tank in accordance with the flow volume of said nitrified wastewater or said nitrified water entering said first tank;
• and
• at least one detention tank in said series of interconnected tanks coupled to an outlet of said mixing tank via said conduit for receiving effluent from said mixing tank.

• a pumping chamber connected to an outlet of a last detention tank in said series of interconnected tanks for receiving said effluent from said last detention tank;
• and
• a pump attached to said pumping chamber for pumping said effluent to an inlet of a filter, said effluent passing through said filter to an exit outlet.
