Problem Statement & Impact - 2,000 people die daily in India due to water and sanitation-related diseases, highlighting the critical need for clean water solutions [2] - Traditional water purification methods like boiling or chemical treatments are often ineffective and unsustainable [5] - Conventional Reverse Osmosis (RO) systems waste a large amount of water, with some systems wasting three glasses of water for every one glass purified [6] Technological Solutions - Ultrafiltration (UF) membranes offer a solution by removing bacteria, viruses, turbidity, and microplastics without electricity, water wastage, or chemicals [9][10] - Systematically Modeled Reverse Osmosis (SRO) dynamically adjusts operation based on water quality, reducing water wastage to 15-30% compared to 70% in regular RO systems [14] - SRO systems purify 1 liter of water while wasting only 0.3 liters, significantly less than regular RO systems [15] Implementation & Impact - The company has supplied over 300,000 units to government schools, farmers, and laborers, and has also provided solutions for defense and emergency situations [10][11] - A water purification plant set up in Namibia provides safe drinking water to a community of 3,000 people, with minimal water wastage used for cattle [19] Future Vision - The company aims to move towards zero water wastage through innovative systems that allow for secondary applications of filtered water [17][18] - The company seeks partnerships to expand its reach and ensure access to clean water for all [20]
