| Arsenic removal | |
| Arsenic is a metalloid naturally present in the underground sources of human drinking water, with the damage to public health that this entails. At present, reverse osmosis is the most popular arsenic removal process. The greatest limitation of this process is the amount of water that the process rejects, sometimes in the order of 50%. This feature and the system’s high operation cost make it prohibitively expensive for many communities, especially in rural areas; it is therefore necessary to find alternatives for arsenic removal. Constructed wetlands have been considered a viable option for As removal in previous studies by our work group and other researchers (Alarcón-Herrera et al., 2007; Núñez-Montoya et al., 2007; Elless et al., 2005). The objective of the present study was to determine the efficiency of E. macrostachya at removing arsenic from a system of constructed wetlands with subsurface flow, as well as the plant’s acclimatization and tolerance to high As concentrations, in order to verify the feasibility of using it at a greater scale for the treatment of the water rejected by reverse osmosis systems. | |
