PopUp filter is the Rainwater
Harvesting filter "Designed and Developed by Mr. A. R. Shivakumar,
patent held at Karnataka State Council
for Science and Technology, Indian Institute of Science, Bangalore".
Features of PopUp Filter
Rainwater collected on the roof is
very pure and clean. However, there are many substances which get mixed
with this pure water on the roof (leaves, bird droppings, dust etc.).
These impurities need to be filtered before the rainwater is stored. An important feature in filtering
rainwater is the separation of the first flush of rainwater from the
relatively cleaner and purer subsequent rain. PopUp filter is a simple device, which is very effective and user friendly.
This filter is working satisfactorily in many residential and smaller
institutional or industrial buildings. PopUp filter is simple in design and very flexible to install
in varying field conditions.
The patent of the PopUp filter
designed by Mr. A.R.Shivakumar is held at the State Council.
KSCST has transferred the technology
to Raj Irritech Pvt. Ltd., Ahmedabad, Gujarat
for commercial production and marketing.
