The first water-treatment system was set up in the village of Alampur, where 25 people have died in the past five years because of exposure to arsenic in the local water. About one in 12 people in the village of 3900 had been ill before the system was installed.
It is HYDROXON's first commercial trial and Dr Walczuk said she hoped the results would trigger more work in developing nations, as well as industrial contracts with manufacturers and agricultural companies, as the system could also be used to decontaminate waste water.
"At the global level the total water treatment market is around $700 billion today," Mr Marquard said. "But there are no dominant players in terms of the total market, with the biggest players still only having a very small percentage of the market."
The HYDROXON systems are able to produce 5000 litres to a million litres of clean water a day. The machines are highly energy efficient and can produce 200,000 litres powered from a household power point.
