MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617091606 A) filed by Hydric Desalination Pty Ltd on July 28, 2026, for Improved Ion Exchange Processes For Softening Water.
Inventor includes Pashley, Richard.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A process for softening hard water comprising the steps of: a) contacting hard water with a thermally regenerable ion exchange resin pre- saturated with ammonium and bicarbonate ions so as to replace 'hard' ions in the feedwater with NH4+ and HCO3- ions; b) heating the ammonium bicarbonate (AB) solution produced to decompose the AB, producing a soft product water of low salinity; c) collecting the emitted ammonia and carbon dioxide gases by bubbling through cool water to re-form the concentrated AB regenerant solution; and d) passing the concentrated ammonium bicarbonate solution through the hardwater exhausted resin, at elevated temperatures (up to 80°C) to partially decompose the AB and generate controlled partial pressures of NH3 and CO2 (up to 10 atm, in a sealed column) to drive the resin regeneration process. e) repeating steps a) to d).
