Abstract
A method of supporting denitrification includes receiving biological material at a pulsed electric field station and applying a pulsed electric field to the biological material within a treatment zone in the pulse electric field station to generate treated biological material. The method also includes transporting at least a portion of the treated biological material to an anoxic bioreactor in substitution, at least in part, for an external source of electron donor. A system for supporting denitrification is also provided.
Claims7
A method of supporting denitrification, the method comprising:
- receiving biological material at a pulsed electric field station;
- applying a non-arcing pulsed electric field with pulses that have a pulse width of 2 to 15 microseconds, a peak field strength of 20 to 60 kV/cm and a frequency of 2000 to 10000 pps, to the biological material within a treatment zone in the pulsed electric field station to generate treated biological material;
- and
- transporting at least a portion of the treated biological material to an anoxic bioreactor in which denitrification is performed on a wastewater having a nitrate concentration with a supply of electron donor and carbon, the at least a portion of the treated biological material used in substitution, at least in part, for an external source of electron donor and carbon to decrease the nitrate concentration.
