| Sumario: | A technological design for water processing for rural and peri-urban areas with no drinking water was created as part of a general project aimed at treating groundwater containing arsenic values higher than those established by the WHO (10 μg L-1) for consumption. The construction of treatment equipments (batch type) is simple and operatively easy. The adsorbent is a low-cost, Fe-rich and clay mineral that is abundant in Buenos Aires Province. Local conditions of water, particularly physicochemical properties, have been taken into account to adapt the process which operates with volumes from 2000 to 4000 L of water/stage. Three plants have been installed in schools of rural areas of Buenos Aires Province. A new plant is being constructed in Inchausti School of the UNLP located in 25 de Mayo city. The equipments provide water in educational buildings and nearby populations. Some technical data about the process are reported in this communication. It is necessary to mention that the first prototype, which was installed two years ago, has been continuously used without having replaced the adsorbent so far. It has processed 400000 L of water whose original concentration of arsenic was around 200 μg L-1 that now reaches values lower than 10 μg L-1. |
