Abstract

Subterranean arsenic removal (SAR) is a sustainable water treatment process to remove arsenic and iron from groundwater without any chemical use or waste generation. The SAR plant creates an aerobic high Eh bed in the aquifer by recharging oxygenated groundwater, thereby supporting the growth of arsenic and iron oxidizing aerobic bacteria. The arsenic and iron are immobilized in the aquifer sand in the forms of As (V) and Fe(III), respectively. This work reports the installation and operation of a SAR plant installed at Tepul village in West Bengal, India. The groundwater was sampled, PHREEQ modelling was done to understand the chemical states of arsenic and iron, and a lithological study was done to identify various layers of the aquifer before selecting the Tepul site for installation of the SAR plant. The naturally occurring second aquifer water at Tepul had an arsenic concentration of 254 ppb. Once the plant was installed and the operation started, the arsenic level decreased to below the WHO limit of 10 ppb for 3000 L per day (LPD) water within 50 days of its operation.
