Title (EN) PROCESS AND SYSTEM FOR WASTEWATER TREATMENT
(FR) PROCÉDÉ ET SYSTÈME DE TRAITEMENT DES EAUX USÉES
Abstract:
(EN) The present disclosure provides a wastewater treatment process comprising: (a) circulating wastewater comprising biodegradable organic material, between an anaerobic digester (AD) and at least one microbial electrolysis cell (MEC), the MEC comprising an anode and a cathode; (b) applying voltage on said anode and said cathode; and (c) discharging from said AD biogas with a methane fraction of above 70%v/v. Also provided by the present disclosure is a biological wastewater treatment system (100) comprising wastewater inlet (104), and (i) an anaerobic digester (AD) comprising biogas outlet (106), and effluent outlet (108); and (ii) at least one microbial electrolysis cell (MEC) comprising an anode and a cathode; said AD and said at least one MEC being in liquid communication through liquid circulation lines (110) configured for at least circulating wastewater between said AD and said at least one MEC.
(FR) La présente invention concerne un procédé de traitement des eaux usées comprenant : (a) la circulation d'eaux usées comprenant un matériau organique biodégradable, entre un digesteur anaérobie (AD) et au moins une cellule d'électrolyse microbienne (MEC), les MEC comprenant une anode et une cathode ; (b) l'application d'une tension sur ladite anode et ladite cathode ; et (c) la décharge dudit biogaz AD avec une fraction de méthane supérieure à 70 % v/v. La présente invention concerne également un système de traitement biologique des eaux usées (100) comprenant une entrée d'eaux usées (104), et (i) un digesteur anaérobie (AD) comprenant une sortie de biogaz (106), et une sortie d'effluent (108) ; et (ii) au moins une cellule d'électrolyse microbienne (MEC) comprenant une anode et une cathode ; ladite AD et ladite au moins une MEC étant en communication liquide par l'intermédiaire de lignes de circulation de liquide (110) configurées pour au moins faire circuler les eaux usées entre ladite AD et ladite au moins une MEC.
