Electrochemical separation of organics and inorganics from industrial wastewaters

The co-occurrence of pollutants such as heavy metals, persistent organics, and nutrients results in metal organics complexes (organometallic complexes), precluding industrial wastewaters' biodegradability and increasing the treatment complexity Several challenges remained in the conventional treatments such as high energy consumption, high operational cost, chemical additives, and limited separation of organics and inorganics Therefore electrochemical technologies have been developed to achieve separation of organics and inorganics due to various advantages over conventional treatments include robust, easy to operate, no/fewer chemical additives and flexible in case of variable wastewater sources The main aim of this PhD thesis is to develop tailored electrochemical technologies following three different target streams to investigate the feasibility of electrochemical systems for separating organics and inorganics from the wastewater water Simultaneously, the pollutants removal and valued products recovery from wastewaters are also evaluated in this thesis Three targets industrial wastewaters were considered (I) Petrochemical wastewater includes both terephthalic acid ( and cobalt (II) F ertilizer manufacturing wastewater includes ammonium and methanol (III) Alkaline automobile shredder residues ( leachate includes copper, zinc and ammonium The overall applicability of electrochemical technologies for the treatment of different stream types has been demonstrated in this thesis, indicating that the process configuration of the electrochemical the system can be tailored, offering versatility for various stream type
