Project Summary

Water is crucial to every aspect of life. While only 2.5 percent of the world is covered by fresh water, just less than 1 percent of our freshwater is easily accessible, much less is always available daily. Many of the world population suffer from clean water scarcity which leads to problems in Health, Hunger, Education, and Poverty. We propose to solve the global clean water crisis by efficiently producing clean water to all by effectively removing toxic chemical from industrial polluted water and desalinating salty sea water through the newly developed nanomembranes with Atomic-Scale Precision sieving capabilities. The CLEAN nanomembrane production will empower people with this fundamental human need to break the cycle of poverty and address health crisis. We plan to focus on Flint, Michigan as a start for demonstration, later will expand to Afghanistan and Ethiopia which are top two places most in need of clean water.

Problem Statement

Water is crucial to every aspect of life. While nearly 70 percent of the world is covered by water, only 2.5 percent of it is fresh. The rest is saline and ocean-based. Even then, just 1 percent of our freshwater is easily accessible, with much of it trapped in glaciers and snowfields. While our planet may never run out of water, but the clean freshwater is not always available where and when humans need it. In fact, half of the world's effects of water scarcity which lead to problems in Health, Hunger, Education, and Poverty. According to the World Economic Forum 1 out of 9 people lack access to safe clean water, near 800 M people living without access to safe clean water and 150 M people depend only on surface unclean water to meet their basic needs. Six times the population of the United States lives without a household clean water connection. More than 2.3 B people living without access to clean water sanitation reported by the World Health Organization and UNICEF. The worst is those underprivileged women and children can only depend on industrial contaminated unsafe drinking water in school and families. The lack of clean water crisis is one of the top global risk and impact to society. The problems we are trying to solve here is global challenges and crisis. Impacts will be millions to billions of populations benefited. The multiple geographical clean water crisis is urgent, and solutions will be provided.

Solution Overview

We will solve global and regional clean water crisis among marginalized people within the underdeveloped countries by newly developed and demonstrated CLEAN (Chemical-Less Efficient Atomic Nanomembrane) water filtration nanomembrane and mass production and deployments to efficiently remove toxic chemical contaminants via atomic-scale precision sieving technologies.Poverty is often caused by a lack of access to clean, safe which lead to political instability, ethnic conflicts, climate change and other man-made causes. The clean water crisis is created by the global epidemic of freshwater pollution and depletion. It is the difficulty of obtaining sources of fresh water for use usually result in further depletion and deterioration of available water resources. The cost of clean water: $150 billion a year, says World Bank. Countries need to quadruple spending to $150 billion a year to deliver universal safe water, helping to reduce childhood disease and deaths while boosting economic growth. Graphene-based advanced nanomembranes have a few major advantages due to its 2D structure: high permeability, high selectivity, low concentration polarization, less fouling, and chemical and physical stability. We will mass produce graphene-based nanomembranes for water purification and water desalination to address global challenges of pollution and scarcity of water. Highly selective and high-permeable next-generation membrane can improve the limitations of the existing less energy efficient membrane technologies. Molecular-level design approaches in these graphene membranes, are the most promising technologies to provide low cost clean water. The multiple geographical water crisis is urgent, and solutions will be provided by the state-of-art Nobel Prize winning technologies.
