Arsenic in water

High concentrations of arsenic in drinking water pose an enormous threat to public health. Drinking arsenic-rich water for a prolonged period of time (e.g. 5 to 20 years) results in arsenic poisoning or arsenicosis. Health effects of arsenicosis are skin problems, skin cancer, and tumors in bladder, lungs, and kidneys. Some causes of the presence of arsenic in water are the dissolution of minerals and ores, wood preservatives, and industrial effluents.

Arsenic in drinking water

Due to the severe health risks, The World Health Organization (WHO) has set the maximum acceptable concentration of arsenic in drinking water to 10 ppb. However, in many regions around the world, these conditions are not met. Some countries where arsenic contamination is present are Bangladesh, China, Argentina, India, and the United States of America. In 2007, it was estimated that more than 137 million people in over 70 countries are affected by some degree of arsenic poisoning. For example, in Bangladesh it was found that 27% of all shallow tube wells contained arsenic levels of more than 50 ppb.

Arsenic removal from water

BiAqua has developed a cost-effective bio-based solution that is capable of extracting arsenic from water, even when present in very low concentrations. The BiAqua solution can be implemented for both industrial and consumer purposes. For example, in an industrial setting, our solution could be used to purify arsenic-rich effluents before they are discharged to surface waters. For consumer purposes, BiAqua is the ideal solution to purify contaminated well water and could also be implemented as point-of-use water treatment solution.

Feel free to contact us about possible applications of our solution for your specific needs.
