Abstract: There are provided processes for treating a residual. For example, such processes can comprise treating a mixture comprising the residual, a peracid or source thereof and an ammonium salt in a reactor, with an electric field, by means of at least one anode and at least one cathode that define therebetween an electrokinetic zone for treating the mixture. Such processes allow for inactivation of at least one type of pathogen in the residual so as to obtain a treated residual.

Abstract: There are provided processes for treating wastewater. The processes can comprise treating a mixture comprising the wastewater and an activated sludge, in a single reactor, with an electric current having a density of less than about 55 A/m2, by means of at least one anode and at least one cathode that define therebetween an electrical zone for treating the mixture; exposing the mixture to an intermittent ON/OFF electrical exposure mode to the electric current in which an OFF period of time is about 1 to about 10 times longer than an ON period of time; and maintaining an adequate oxidation-reduction potential in the single reactor. Such processes allow for substantial removal of carbon, nitrogen and phosphorus from the wastewater in the single reactor of various forms and for obtaining another mixture comprising a treated wastewater and solids.
