MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202621058522 A) filed by Doshion Polyscience Pvt Ltd on May 08, 2026, for Advanced Polymeric Filtration Resin Composition With Fusion Matrix Porosity For High-Efficient Water Treatment Systems.
Inventor includes Ashit Dhirajlal Doshi.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: Describedhereinisa'Polyfilt',anadvancedpolymericfiltration resinforwater treatment comprising spherical beads of cross-linked styrene- divinylbenzene copolymer with an engineered fusion matrix porosity. The resin is characterized by a low bulk density (650-750 grams per liter) and near- neutral specific gravity (~1.05), enabling high efficiency depth filtration and a 100% bedexpansion at ultra- lowbackwash velocities (6-10 meters perhour). This hydraulic profile allows effective media cleaningusinga single rawwater pump in small-to-medium-scale Fiber Reinforced Plastic systems filtration plant. Experimental results demonstrate that Polyfilt reduces raw water turbidity from up to40Nephelometric Turbidity Units down to consistently less than 0.2 Nephelometric Turbidity Units and maintains an effluent Silt Density Index of less than 5.0. The invention includes the resin composition, a low energy filtration process, Low backwash water generationand a system architecture optimized for membrane pretreatment.
