EFFLUENT TREATMENT COMBINING SOLID/LIQUID SEPARATION AND PULSED ELECTRIC FIELDS

摘要

The invention describes the treatment of effluents in which a flow of said effluents is subjected and a pulsed electric field responsible for a physicochemical and biological modification of the medium, put to good use during a solid / liquid separation operation. decantation type or membrane filtration. Solid / liquid separation (13, 14, 15) and pulsed electric field (12) submission are operations at different locations of the effluent stream. The pulsed electric field has characteristics of voltage value, current value, pulse repetition frequency and voltage front shape chosen for, depending on the locations where the membrane filtration and pulsed electric field, get the desired treatment of effluents.
