Processes for treatment of residuals

A process for treating a residual, said process comprising:

• treating a mixture comprising the residual, a peracid or a source thereof and an ammonium salt, in a reactor, with an electric field at a voltage gradient of less than about 8 V/cm, by means of at least one anode and at least one cathode that define therebetween an electrokinetic zone for treating the mixture, thereby generating a temperature in the electrokinetic zone of about 62° C. to about 95° C.,
• thereby allowing for inactivation of at least one spore in the residual by at least a log 5 reduction, so as to obtain a treated residual,
• wherein the ratio of the concentration of peracid or source thereof to the concentration of ammonium salt is about 0.1 to about 0.5, and
• wherein the peracid or source thereof is peracetic acid or a source of peracetic acid, and
• wherein the mixture is treated for a time of less than about 4 hours.
