Notes

  • Researchers at BITS Pilani, Hyderabad, have developed a low-energy technology for treating biopharmaceutical fermentation wastewater.
  • The technology is designed to disinfect wastewater while recovering reusable water and methane-rich biogas.
  • Biopharmaceutical wastewater contains live production microorganisms, residual antibiotics, and antibiotic resistance genes, making it difficult to treat.
  • Current industrial methods rely on chemical treatment and steam-based autoclaving, which are energy-intensive and costly.
  • The new system uses an integrated three-stage process: electrical disinfection, biological treatment, and energy recovery.
  • The project is supported by the Department of Science and Technology (DST) under its water technology initiative programme.
  • The technology is being scaled for industrial deployment in collaboration with Biological E. Ltd.
  • A patent for the core disinfection technology has been filed in India.
