| Abstract | Due to water scarcity and population growth the use of treated wastewater in agriculture has become more frequent.With this motivation, several technologies have been introduced for the treatment of wastewater. The present work aimed at thetertiary treatment of the polluted water of Tataouine sewage treatment plant (Tunisia) using three alternative processes, namelyelectro-coagulation (EC), electro-Fenton (EF), and advanced electro-oxidation (AEO). After 180 min, chemical oxygen demand(COD) and biochemical oxygen demand (BOD5) abatement rates reached respectively 56% and 14% with sharp deterioration ofgerms by EC process, and 75% and 52% with complete degradation of germs when EF process was applied. On the other hand,with AEO process, abatement rates of COD and BOD5 were 92% and 57%, respectively, with complete degradation of germs.The economic study showed that the EF process is technically and economically the best of these alternatives for treatment ofthis wastewater. |
