Title:
Development of a novel water filtration unit containing hybrid adsorbents for simultaneous removal of arsenic and fluoride from contaminated water 
Inventor(s):
Prasenjit Mondal and Vineet Kumar Rathore 
Applicant:
Indian Institute of Technology (IIT) Roorkee 
Application type:
Applied - 2018-07-17 
Application Number:
201811026603 
Applied at:
India 
Entered by:
Indian Institute of Technology (IIT) Roorkee 
Abstract:
The present invention provides a system and method for simultaneous removal of arsenic (As) and fluoride (F) from contaminated water in a customized adsorption column (filter unit) using novel hybrid adsorbent. The system is easy to operate as it does not require any coagulants or oxidizing agents. It contains F reach ABTL and Al reaches AHNP, which are useful in removing As and F. The system uses a low cost adsorbent from laterite soil (ABTL) and aluminum oxide/hydroxide nanoparticle (AHNP) adsorbent with high As and F adsorption capacity, which were mixed in different ratio to get optimum recipe for addressing different situation with As and F in a wider range. The entire system works with the help of gravity, hence does not requires any power to operate. 

 
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.
