Kanchan Arsenic Filter Description
Description
The Kanchan™Arsenic Filter (KAF) is an innovative household drinking water treatment device for removing arsenic, pathogens, iron, turbidity, odour, and some other contaminants in drinking water.
Development
This filter was developed by researchers at Massachusetts Institute of Technology (MIT), Environment and Public Health Organization (ENPHO) of Nepal, and Rural Water Supply and Sanitation Support Programme (RWSSSP) of Nepal, based on slow sand filtration and iron hydroxide adsorption principles.

Performance
Performance
Independent field studies of the KAF in Nepal by the Tribhuvan University, Kathmandu University, and United States Peace Corp showed 87-95+% arsenic removal rate.
Flow Rate
The design flow rate of the Gem505 version is 15 -20 liters per hour, which is adequate even for a large family of 20 people.
