Advanced oxidation technology

In news

A new technology may soon enhance the reuse of waste water in an affordable and sustainable manner.

About the technology
  • The technology which uses UV-Photocatalysis can treat municipal sewage and highly polluting industrial wastewater streams and increase its reuse as a technological option in industrial as well as municipal wastewater treatments.
  • With ever-increasing water crisis, it becomes imperative for industries & utilities to reuse ‘treated water’.
  • However, the current treatment practices are inefficient because of high dependence on biological treatment systems, which are unable to bear shock loads.
  • This is followed by tertiary treatment systems involving RO and Multi Effect Evaporators (MEE).
  • These systems have large carbon footprint and maintenance costs making the wastewater treatment highly unsustainable and unaffordable.
  • These researchers have felt the need to integrate novel approaches and advanced technologies in current systems.
  • The technology supported by the Water Technology Initiative (WTI) of the Department of Science and Technology, Govt. of India involves UV-Photocatalysis as an Advanced Oxidation Process (AOP) at the secondary treatment stage leading to oxidative degradation and mineralization of targeted pollutants.
  • It improves biodegradability, thereby preventing bio-fouling of membranes and enhancing life span and efficiency of RO systems as also overall load on evaporators like Multiple Effect Evaporators and Mechanical vapor recompression (MVR), and so on.
  • It can reduce Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), dissolved organics, pathogens, Persistent Organic Pollutants (POPs), and Micropollutants.
