"water-purifier"

A gravity-based, zero-energy water purifier developed by CSIR-NEERI is providing relief in flood-hit Assam’s Jorhat district, where potable water is scarce. Officials distributed 100 NEERI-ZAR units, including household and community systems, designed to supply drinking and cooking water without electricity
