The duckweed species not only shows potential to solve the water pollution crisis in the country; it can effectively purify polluted water and turn nitric oxide into biological fertilizer.
Contaminated drinking water news: NEERI develops indigenous process to reduce high fluoride in water content.
The National Environmental Engineering Research Institute (CSIR-NEERI) developed an indigenous and economically viable process to reduce high fluoride content in potable water, which would have a domestic and community applications.The chemo-defluoridation of potable water with high fluoride content is achieved in collaboration with the Mumbai-based Rajeev Gandhi Science and Technology Commission, and can be used for reduction of fluoride concentration from 5-8 mg/L to < 1.0 mg/L (miligram per litre). The process does not affect the palatability of water.
