Selenium (Se) is a chemical element of concern due to its toxicity and increasing anthropogenic release to the environment. In the current work one of its oxidation states, elemental selenium, Se(0), was investigated with regard to its colloidal properties and solid-liquid separation potential. Among the techniques used, chemical coagulation (addition of metal salts) and electrocoagulation (electrogeneration of the coagulant in situ using an electric charge) showed the...
More Description
Selenium (Se) is a chemical element of concern due to its toxicity and increasing anthropogenic release to the environment. In the current work one of its oxidation states, elemental selenium, Se(0), was investigated with regard to its colloidal properties and solid-liquid separation potential. Among the techniques used, chemical coagulation (addition of metal salts) and electrocoagulation (electrogeneration of the coagulant in situ using an electric charge) showed the highest removal efficiency. In conclusion, biogenic Se(0) must be removed in a biological post-treatment step and several approaches described in this work could be successfully used.
