The Meherpur district in the western region of Bangladesh has been plagued with problems stemming from the high levels of arsenic in the groundwater.

Exposure to arsenic in drinking water can cause cancer, skin lesions, cardiovascular diseases and impediments in cognitive development. Data from a national survey estimates an annual death toll of nearly 43,000 from arsenic poisoning.

Over the years the government has trialled multiple technologies to treat this water economically but has not been successful in finding a comprehensive solution.

The village is very remote so it was essential that the water treatment plant was easy to operate, robust and reliable. Secondly, the treated water was required to meet WHO drinking water guidelines (arsenic < 0.01mg/l) which are more stringent that the Bangladesh guidelines for arsenic (arsenic < 0.05mg/l).

In association with the Government's Department of Public Health Engineering (DPHE), Infinite Water ran a 8,000 litersday pilot evaluation to prove the efficacy of Hydroxon™ for arsenic removal.

The process successfully reduced arsenic concentrations from 0.2 mg/L to less than 0.004 mg/L bringing it in full compliance with WHO standards (0.01 mg/L) for drinking water.
