Description of a Fe/Al Electrocoagulation Method Powered by a Photovoltaic System, for the (Pre-)Treatment of Municipal Wastewater of a Small Community in Northern Greece

Small and insular communities are sometimes not served by an efficient Wastewater Treatment Plant, this is a hazard for both the environment public health. A wastewater treatment apparatus based on electrocoagulation process (EC) was tested with municipal from small community in Northern Greece maximum of 6500 population equivalents. COD decrease assessed under various parameters: current intensity, time duration, pH use Fe or Al electrodes. simulation meeting community’s electricity needs through RETScreen software. The results showed satisfactory which affected all parameters mentioned; electrodes could efficiently be used at 300 mA 60 min 55% removal. It also shown that photovoltaic panel system covers apparatus, thus no external source needed its use. This effectively community, so running costs minimal.
