Dhaka
Nearly half of Bangladesh's 130 million population will get a reprieve following the recent successful research in the treatment of arsenic contaminated water. Called the Direct Coprecipitation Filtration ( dcf ), "the technique uses an iron coagulate tablet that is immersed into a bucket of water,' said Xiaoguang Meng, an associate research professor at Stevens Institute of Technology (sit) in New Jersey. He explained: "The tablet dissolves in the water, binding with the arsenic molecules present therein. The water is then filtered through highly absorptive sand contained in another bucket.'
