Modular treatment of arsenic-laden brackish groundwater …
Anoxic groundwater with As(III) and Fe 2+ was treated using a pre-oxidation step called subsurface arsenic removal (SAR) with the main advantage that no As-laden waste is produced. The pilot plant was operated using a photovoltaic system (3 kW p) and a small wind turbine (2 kW p). The SEC of drinking water produced was 3.97 kWh/m 3.
