Sixteen dollars!That's the price of a movie ticket plus tax in Los Angeles. Thanks to an Indian chemist,that amount of cash could also provide clean water for a year for a poor family in the developing world.
Thalappil Pradeep,a chemistry professor at the Indian Institute of Technology,spent 14 years developing a water filter(滤水器) system that can. remove pollutants from India's groundwater as it is being pumped. The water purifier,which Pradeep first showed to the public in 2012,is the first filter of its kind in India. The country's federal government recently decided to place the pumps across the nation,Pradeep said. He and a team of students formed a company to keep up with the work,he added.
The device（设备） come in two sizes and at three price levels,which include installation (安装) costs: The $16 version is for homes; a larger one that can be used at schools and office buildings is $500 (connecting a whole village costs $700 more) . The larger purifier,which stands nine feet tall,produces about 80 gallons of clean water per hour.
Worldwide,663 million people do not have access to clean and safe water. In India,access to clean water is particularly poor. About 21 percent of illnesses in India are caused by drinking dirty water,and more than 100,000 deaths are caused by water-borne illnesses each year.
The first of Pradeep‘s pumps was "installed in West Bengal,a state in eastern India,in 2012. The state government took notice and installed pumps at 330 schools across the region. As a result,now about 500,000 people have access to clean water from these pumps,said Pradeep.
