MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202611110119 A) filed by Perminder Singh; and Vega Mahajan on September 14, 2026, for Sustainable Zero- Liquid- Discharge- Zld Effluent Treatment Infrastructure And Intelligent Process.
Inventors include Perminder Singh; and Vega Mahajan.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: An integrated sustainable Zero-Liquid-Disch Hf r' (ZLD) effluent treatment infrastructure and process for pharmaceutical wastewakr is disclosed. The system comprises 10 wastewater segregation, equalization, pre-treatment, biological and/or bio-enzyme treatment, advanced oxidation, membrane ·.r·paration, reverse osmosis, recoveredwater management, thermal. concentration dild crystallization/drying. Online sensors measure flow, pH, COD, TDS, conductivity, temperature, pressure and selected pharmaceutical/ API contaminants. A controll£·r £'valuates the measured parameters and 15 automatically controls treatment and water routing. Recovered water is directed to an approved industrial reuse application aftc: quality verification, while membrane concentrate is subjected to evaporation and :rystallization to generate substantially solid residue. A flow-based mass-balance system verifies the ZLD condition and identifies unintended liquid discharge. The infrastrur:lme provides a modular, scalable and 20 intelligent approach for pharmaceutical w 1stewater treatment, water recovery, industrial reuse and substantially zero routine liquid discharge.
