Abstract
As per the World Health organization (WHO) requirement, the water for drinking purposes should be 100% virus free. This invention reports a polymer impregnated porous substrate membrane and method for the preparation of said membrane for capturing viruses from water. The water filtered through the membrane prepared by the process of the present invention has been tested to be virus free and fully potable based on the tests carried out at the Department of Microbiology, All India Institute of Medical Sciences, New Delhi, India and Sriram Institute for Industrial Research (an ISO 9001 R&D Organization), New Delhi, India. The invention will be of immense use especially for the developing countries and third world countries which are subjected to the problem of unsafe drinking water. This invention is useful also for the developed countries for use in water treatment plants due to highly industrialized nature and existence of a variety of manufacturing units like chemicals and fertilizers.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
