A new research findings by a group at Jawaharlal Nehru University (JNU) shocked the country. According to the new findings, RO water purifying filters can cause serious health hazards for human and animals. The reverse-osmosis (RO) water purifier at home seems to be a benign invention, allowing people to drink clean, healthy water. But now scientists are warning that rampant use of the RO technology could pose a serious threat to public health.
One of the most popular water purifying technologies in India, the RO process is efficient in terms of filtering out toxic substances like arsenic and fluoride, especially in areas where groundwater is heavily contaminated. Simultaneously, though, RO systems, at both household and industrial levels plough back concentrated amounts of these substances back into the aquifers.
