“…The equipment is based on an optimized coagulation/filtration technology with a previous oxidation step, which does not need electric supply. This system was applied in the province of Chaco and in the groundwater of the town of Lobos, province of Buenos Aires (INTI-Química, 2009;Frangie et al, 2014). Another experience is the implementation of POU based on adsorption on synthetic granular ferric hydroxide fixed beds (Bahr and Ewy, 2014) in four localities of Argentina including Junín, Suipacha and Chivilcoy in the province of Buenos Aires.…”
