Περίληψη | A battery scheme comprising sequential alum coagulation, activated-carbon adsorption and electrochemical oxidation over boron-doped diamond electrodes to mineralize a leachate from olive pomace processing is demonstrated. The effect of coagulant and adsorbent concentration on treatment efficiency was assessed in the range 0.1–50 mM Al3+ and 2.5–50 g/L activated-carbon and optimal conditions were established. Coagulation at 7.5 mM Al3+ resulted in substantial solids and color removal (i.e. 80% and 93%, respectively). This was accompanied by only 30% chemical oxygen demand (COD) reduction (initial COD was about 3500 mg/L). The latter increased to 80% though when coagulation was coupled with adsorption at 25 g/L activated carbon.
Electrochemical oxidation of the original effluent for 360 min led to 63% and 82% COD reduction at 10 and 20 A current intensity, respectively. When this process was tested as a polishing stage following coagulation and adsorption, overall COD removal reached values of 92% and 97%, respectively. The final effluent was also colorless and solids free. However, the treated effluent still exhibited ecotoxicity possibly due to the formation of ecotoxic oxidation products. | en |
