A group of students from the Department of Electrical and Electronics Engineering (EEE) at the Federal Institute of Science and Technology (Fisat), Angamaly, has secured a patent for a portable water purification device named HydraPure – Smart Portable Filter Bottle. The innovation was developed by final-year students Anna Shijo, Appu Anikumar, Abhay Sajesh, and Mohammed Shareef under the mentorship of Assistant Professor Rinku Scaria. The patent application was filed through the institution’s Intellectual Property Rights Cell.
HydraPure: A Three-Stage Purification System
According to the student team, HydraPure is designed as a portable water treatment solution for commuters, travelers, and others who rely on public water sources. The bottle incorporates a three-stage purification system consisting of activated charcoal filtration, ozone generation, and ultraviolet-C (UVC) treatment.
How It Works
The activated charcoal filter is intended to reduce chlorine, odors, and certain chemical impurities in water. The bottle also features a miniature ozone generator and UVC LEDs operating in the 250–280 nanometer wavelength range. The entire purification process is controlled by an embedded microcontroller.
“We wanted to work on a socially relevant innovation and eventually focused on the need for an affordable drinking water purification system,” said Anna Shijo. She added that the prototype was developed at a cost of less than Rs 1,000 and that large-scale manufacturing could potentially reduce production costs further.
Power and Charging
The device is powered by a rechargeable battery and supports charging via a USB Type-C port. “The invention reflects the application of engineering concepts to address practical challenges related to water use and sustainability,” said Scaria, who mentored the project.
The students expressed hope that the technology can contribute to accessible and portable water purification solutions in the future.
