Inventor(s) include Dr. Pranaya Rameshwar Diwate; Prasanna Pramodrao Lavhale; Dr. Praful Shinde; Aditya Yadav; Pranali Kathe; and Prasad Bhagile.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a Zeolite-Based Filtration System for sustainable removal of toxic pollutants from surface Water. The system employs a specially designed filter bed comprising natural or synthetic zeolite media to adsorb and exchange ions with toxic contaminants, including heavy metals and organic pollutants, from surface water. The zeolite material, possessing a crystalline aluminosilicate structure with high cation-exchange capacity, facilitates selective adsorption of harmful substances through molecular sieving and ion-exchange mechanisms. The filtration bed is arranged in a layered configuration that ensures uniform hydraulic flow, minimal clogging, and high contact efficiency between water and filtration media. The invention integrates structural and operational features enabling regeneration of the zeolite media through ion-exchange or thermal treatment, allowing repeated use without environmental degradation. The system offers a sustainable, energy-efficient, and cost-effective solution for water purification, suitable for deployment across surface water bodies applications. It reduces chemical dependency, enhances pollutant removal efficiency, and supports large-scale clean water initiatives aligned with environmental sustainability objectives."
