Abstract:
1. A method for treatment of effluents comprising: subjecting a flow of the effluents to a pulsed electric field that has an effect of modifying physicochemical and biologic characteristics, the modifying being used during a solid/liquid separation operation, the solid/liquid separation and an application of the pulsed electric field being operations carried out at different locations in the effluent flow; and pulsing said electric field by, charging a capacitor with a D/C power supply in a first mode where the D/C power supply is in a closed circuit with the capacitor, discharging a charge in the capacitor through a load inductor connected in series with a treatment head and an inductor connected in parallel to the treatment head for limiting a charge current applied to the effluents during a pulse discharge in a second mode by opening the circuit between the capacitor and the D/C power supply and closing the circuit between the capacitor and the treatment head, and switching between the first and second modes to produce a pulsing electric field in the treatment head.
