Inventor(s) include Saraswati Vijaysingh Patil; Anish Manish Chawla; Aryan Sunil Chugera; Ridhima Aditya Chandorkar; and Shubhamkar Sunil Deo.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "This project presents an integrated microplastic detection and filtration system that combines optical sensing, deep learning, and multi-layer filtration for efficient water quality monitoring and purification. Water samples are analyzed directly in a detection module, where 365 run UV illumination induces polymer fluorescence, allowing a USB microscope and Raspberry Pi to capture and process high-resolution images. Using the YOLO deep learning model, the system performs real-time detection, classification, and quantification of microplastics. Simultaneously, the main water flow passes through a three-layer filtration unit consisting of jute felt ( 50 microns), 120 mesh nylon (100-125 microns), and 400 mesh nylon (25-37 microns), ensuring progressive mechanical removal of microplastic particles of varying sizes. Controlled by a microcontroller-based module, the system maintains optimal flow and safety through continuous feedback from a pressure sensor (HX711) and a flow sensor (YFS401), automatically adjusting pump speed to prevent filter clogging. This dual-process design enables both purification and live verification of microplastic contamination, providing a cost-effective, automated solution for environmental water analysis and treatment."
