Norra, Giannis-Florjan published the artcileRemoval of persistent organic contaminants from wastewater using a hybrid electrochemical-granular activated carbon (GAC) system, HPLC of Formula: 117-96-4, the main research area is granular activated carbon organic contaminant wastewater treatment.
A three-dimensional (3D) electrochem. flow-through reactor equipped with GAC packed bed, polarized by the elec. field, was evaluated for the removal of persistent organic contaminants from real sewage effluent. The performance of the reactor was investigated for 27 consecutive runs at two anodic current densities, i.e., low c.d. (LCD) of 15 A m-2, and high c.d. (HCD) of 100 A m-2. In the HCD experiments, the adsorption ability of saturated GAC was increased, mainly due to the increase in the mesoporosity of GAC. A synergy between electrosorption/adsorption on GAC and electrooxidation was observed in terms of the removal of all target pollutants. DEET presented the highest synergy, ranging from 40% to 57%, followed by iopromide (22-46%), carbamazepine (15-34%) and diatrizoate (4-30%). The addition of GAC decreased the concentrations of toxic chlorate and perchlorate by 2-fold and 10-fold, resp., due to their electrosorption on GAC. Also, 3D electrochem. system yielded lower concentrations of adsorbable organic iodide (AOI) and adsorbable organic chlorine (AOCl). Thus, addition of low amounts of GAC in electrochem. systems may be a low-cost and simple way of minimizing the formation and final effluent concentrations of toxic halogenated byproducts.
