Concept Note on hybrid Constructed Floating Wetland for in-situ Water Body Rejuvenation
Principal Investigator
Prof. Ligy Philip
Objective
- Implement and demonstrate a novel low-energy technology for in-situ water body rejuvenation based on a hybrid constructed floating wetland (HCFW) system under field conditions, to act as a "model" for large scale replication.
Description
- Global water scarcity, intensified by population growth, urbanization, and pollution, threatens sustainability and public health. A major concern is freshwater contamination by nutrients and emerging pollutants?especially pharmaceutical and personal care products (PPCPs)., While advanced technologies like ozonation and membrane filtration are effective, they are costly and unsuitable for resource-limited regions., In this context, researchers at IIT Madras (Prof. Ligy and her student) have come up with a novel idea for sustainable in-situ rejuvenation of water bodies by a nature-based solution (NBS).
Impact
- Applicability of the system has been demonstrated conclusively in the lab-scale model tests. Through extensive lab tests, Prof. Ligy and her student Mr. Bheshkumar Karki have gained detailed insight into the mechanism of contaminant removal., AquaMAP is looking for industry partners for field demonstration of the Treatment of waterbody through a hybrid system involving phytoremediation and bioactive biochar (bioactive carbon).
