Title:
A SYSTEM AND A PROCESS FOR WASTEWATER PURIFICATION  
Inventor(s):
DUTTA, Arnab; GHOROI, Chinmay; ALI, Afsar 
Applicant:
Indian Institute of Technology (IIT) Gandhinagar 
Application type:
Provisional - 2019-11-11 
Application Number:
201921045779 
Applied at:
India 
Entered by:
Indian Institute of Technology (IIT) Gandhinagar 
Abstract:
The existing technologies for water purification have disadvantages such as they are unable to provide environment-friendly, user-friendly, cost-effective measures for the proper disposal of hazardous materials from industrial wastewater and release of hazardous by-products during the purification process. The present disclosure envisages a wastewater treatment process comprising of the following steps:  treating an influent wastewater stream (106) with a transition metal complex stream (108) (MC), containing a redox-active ligand framework in a degradation unit (102).  adding stoichiometric amount of Hydrogen Peroxide (H2O2) which activates the MC to initiate the oxidiation of the organic dye chemicals to reduce the chemical oxygen demand (COD) and to some extent total dissolved solids (TDS) of the solution by 80-98% and 30-50%, respectively. 

 
THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
