Vajra Kavach - Disinfection System

Mumbai-based start-up, Indra water has developed “Vajra Kavach Disinfection System” removes scourge of viral particles from equipment used by Corona warriors front line workers. This Vajra Kavach has been installed at multiple government hospitals in Maharashtra and Telangana, according to a statement by the Ministry of Health and Family Welfare (MoH&FW).

Vajra Kavach Disinfection System

   What is Disinfection System

1. The disinfection system removes any possible traces of SARS-Cov-2 virus from Personal Protective Equipment, coats, gloves, N95 masks, and gowns.
2. Thus, it enables the reuse of PPEs and other equipment used by healthcare workers.
3. In a way, it will protect the environment too, by reducing biomedical waste generation.
4. It will make personal protective equipment more available, affordable, and accessible.
5. Disinfection can be done in just a few minutes.
6. The system can achieve a 1,00,000-fold reduction in the number of microorganisms.

Where this System was Developed?

Validation and testing of the system was done by the Department of Biosciences & Bioengineering at IIT Bombay.

How testing was done?

It went through a long trial and testing process. Testing was done with Escherichia virus MS2; which is a single-stranded RNA virus similar to human respiratory viruses like influenza virus and coronavirus; and E.coli strain C3000. While testing it, full loads of virus and bacteria samples were placed PPE kit and were then placed inside Vajra Kavach. After disinfection cycle time, PPE was removed and the sample was rechecked to assess the growth rate and log reduction of the virus.

How this system disinfects materials?

The system comprises of multistage disinfection process having advanced oxidation, corona discharge, and UV-C light spectrum which inactivate viruses, bacteria, and other microbial strains from materials.
