Title:	Compact Membrane Pilot Plants for Removal of Fluoride, Arsenic, and Nitrate From Ground Water by Reverse Osmosis
Area:	Earth, Atmosphere & Environment Sciences
Focus Area:	Water-based Technologies
Status:	Technogy is tranfered for real field application. RO plants are installed in Andhra Pradesh, Telangana and Tamilnadu to provide safe drinking water to school children who otherwise were drinking contaminated pond water directly.
Patent:	Developed with the help of permionics private limited for rural applications.
Social Benefits:	Flouride, arsenic and other heavy metal contamination is one of the major problem affecting a major population that is being adressed by installing these plants. This plant removes all impurities, arsenic, fluoride and nitrate in a single step including excess total dissolved solids (TDS). Retention of sufficient mineral content, Ca, Mg, P, Na, K essential for human consumption and health. Provides purified water for small habitats of 10 to 20 hamlets such as schools, colleges and hospitals.

Brief Description

Description :

This technology utilizes compact membrane-based systems, particularly reverse osmosis, to remove multiple contaminants such as fluoride, arsenic, and nitrate from groundwater. It is designed as a pilot-scale plant for deployment in contaminated regions, ensuring production of safe drinking water. The system provides high removal efficiency for dissolved contaminants and can be scaled depending on requirement. Key Features: • Removes multiple contaminants including fluoride, arsenic, and nitrate • Based on reverse osmosis membrane technology • Compact and scalable pilot plant design • Suitable for groundwater purification in affected regions • Ensures production of safe drinking water
