Organic Arsenic Sorber (OaS) is a treated laterite based nano-porus media for the removal of Arsenic and other heavy-metals from the water. Listed as top-100 technologies from India, this award winning adsortion based media is low-cost, long-life, and TCL Protocol complient is a robust solution for critical water quality soltion.
Our activated charcoal based media has nano-silver & nano-copper impregnation to ensure 99.5%+ remidiation of micro-organism in the water, without using any synthetic material. Different kinds of charcoal bassed media has been optimised for different kinds of use cases; ranging from drinking water purification to Net-Zero solutions. Â
Our approach
This mission aligns with the United Nations Decade for Action Agenda (2018-2028) and supports the achievement of Sustainable Development Goals (SDG 2030). By integrating clean water access with an eco-conscious economic system, the initiative empowers rural communities while ensuring environmental sustainability.
The BarterWATER initiative is based on an innovative incentive system that rewards efforts in community action with Rainbow Credits. These credits can be redeemed for clean drinking water from OAS Spring units or exchanged for essential nature-based goods and services, fostering a culture of responsible water use at the grassroots level.Â
In addition to the innovative ‘barter-for-impact’ model, the solution is deploying pioneering research from IIT-Kharagpur to tackle Arsenic contamination in the water sources using commonly found laterite mineral for binding and safe disposal of Arsenic.Â
Arsenic has had a devastating health impact on communities across at least eight States in North India, where communities lack affordable and easy-to-deploy solutions and suffer from high cancer rates.Â
With technological innovation, strong institutional support, and active community participation, the BarterWATER initiative is paving the way for a water-secure and environmentally responsible future, proving that sustainable solutions can be both impactful and scalable.
