MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611050089 A) filed by Birla Institute Of Technology And Science, Pilani, Rajasthan, on April 20, for 'intergrated-ultraviolet-c activated persulfate disinfection and electrochemical-sorption cum desorption system and method for producing safe water.'
Inventor(s) include Atul Patel; and Halan Prakash.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to an integrated system and method for producing safe potable water through sequential UVC/PS disinfection and ESD. Raw water containing ionic species and microbial contaminants (103CFU/100mL) is first dosed and passed through a cylindrical ultraviolet-C reactor (3). A contact time of 5.76 seconds facilitates the generation of sulfate radicals, ensuring complete inactivation of heterotrophic bacteria and coliforms while preventing post-treatment regrowth in tap water. The disinfected water, containing 84% residual PS, is subsequently processed in an ESD unit (7). Under a DC potential, 1.2 V (6), PS anions are electrostatically captured/desorbed within the micropores of ion-selective membrane-coated carbon electrodes. In the electro sorption phase cytotoxic PS concentrations reduces to non-cytotoxic levels below 0.6 mM, verified by real-time conductivity monitoring (8, 9) and PS concentration measurements. Further, in the desorption phase, 94 % of PS was recovered. The invention provides disinfection and residual oxidant removal to produce safe domestic water (10)."
