To combat the Arsenic catastrophe
The Arsenic catastrophe is the largest mass poisoning in history.
The World Bank has allocated $ 44.4 M for a project to remedy the Arsenic catastrophe in Bangladesh. There are many options to choose from but it is a very difficult task.
Arsenic in Drinking Water, a report from WHO given in may 2001 states that:
There are no proven technologies for the removal of arsenic at water collections points such as wells, hand-pumps and springs.
Technologies and Costs for Removal of Arsenic from Drinking Water, a report by EPA given in December 2000 scrutinizes all technologies available for Arsenic removal. The conclusion is that large purification plants may, at a cost, adapt to arsenic removal, but for small plants, private wells and households, there is no simple solution.
Many of the Arsenic combating technologies that have been recommended this far have turned out to do a good job at removing the relatively harmless type of Arsenic (As+5) but not the very poisonous type (As+3). Scarab has developed the only presently known technology that removes Arsenic from water in a simple and reliable way and does it completely.
