The actual wastewater treatment includes a number of precipitation, neutralization, clarifying and filtering steps. This manuscript proposes a new sustainable process that would eliminate/reduce several of the disadvantages in an actual copper wastewater treatment such as a) reduced lime addition, b) a separate gypsum and heavy metal/arsenic precipitation, c) an electrodialysis stage that would recover copper, d) an easier ferric ion dosage for arsenic removal by electrocoagulation, and e) a less reagent consuming neutralization step.</p><p class="04KEYWORD">Keyword: Sustainable wastewater treatment, Electrocoagulation, Arsenic removal, Copper recovery</p>}, number={3}, journal={European Journal of Sustainable Development}, author={Hansen, Henrik K. and Rojo, Adrián and Gutiérrez, Claudia}, year={2016}, month={Oct.}, pages={159} }
