“…The initial wastewater pH may affect the overall EC performance. The differences noted here may be due to the prevailing coagulants' form [Fe(OH) 2 , Fe(OH) 3 and Al(OH) 3 ] between pH 6 and 8 [38]. This is within the range of typical municipal wastewater samples (see Table 2).…”

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

Electrochemical treatment is an effective method to improve physicochemical characteristics of effluents and to minimize the environmental footprint of anaerobic digestion facilities. In the present research an anaerobic digester effluent was subjected to post-treatment, using electro-oxidation or electrocoagulation processes for significant reduction of Chemical oxygen demand and ammonia. A combined electro-oxidation and electrocoagulation treatment was also performed. Results show satisfactory decrease of both Chemical oxygen demand and ammonium nitrogen, which however were relative to the method applied, the time duration and the current intensity. A combined use of both methods may be the best solution for the post-treatment of this high burden effluent. All the presented values have occurred from experiments in the Chemistry Department of the International Hellenic University.

Despite the promising application of microorganisms for purification of metal-containing wastewater such biotechnologies have not been widely used since their empirical basis. Therefore, the aim of our work was to apply thermodynamic prognosis to determine the optimal pathway of microbial removal of toxic metals (CrO42-, Cu2+) and its experimental justification. There was theoretically substantiated on the base of thermodynamic prognosis and experimentally confirmed integration of microbial reduction of metals, and their precipitation by microorganisms. Developed approach is the methodological basis for fast and effective purification of metal-containing wastewater.
