We live on a blue planet where most of the surface is water. Yet it is sobering to know that only 3 percent is fresh water. Of that 3 percent, two-thirds are out of our reach or polluted.
This finite resource continues to be threatened by a growing world population, climate change, and increasing environmental pollution. A powerful confluence of potentially disastrous factors—pushing us deeper into a global water crisis.
According to the United Nations, half of the planet will suffer from water scarcity by 2050, including severe water stress by 2030. Population growth and climate shifts are threatening the entire water cycle. Changes in precipitation are depleting rivers and aquifers. The ground is becoming arid in many areas affecting the capacity to store water.
Beyond water scarcity, another major threat is spiralling water pollution, including from “forever chemicals” used in products since the 1940s. These chemicals are strong bonds of synthetic per- and poly-fluoroalkyl chemicals known as PFAS. Through their use in consumer products, including in food packaging, PFAS end up in the water and linger in our bodies, including in mothers’ milk and babies’ vascular systems. Studies show PFAS can interfere with the developmental functions of children. The U.S. Environmental Protection Agency recently introduced strict laws to control the level of these chemicals in drinking water. The military is also taking action by requiring PFAS-free firefighting foams.
On top of climate change, pollution, and increasing demand—our nation’s municipal water systems require urgent modernization to provide safe water. Some components of these systems date back to the 1800s, the majority built in the 1970s. Studies show at least 21 million people in the U.S. drink water that violates federal safety standards. Our infrastructure has been neglected and underfunded for many years. What we filter is not solely determined by health studies. It is also a decision based on economics and cost-benefit analysis. Multiple public health crises have already happened (think Flint, Michigan), with more on the horizon unless we deploy affordable and reliable technology.
- How do we face such a complex and layered crisis? While vexing, solutions are available if we work together. Researchers at the Nanotechnology Enabled Water Treatment Center (NEWT) are developing solutions through convergence research across many disciplines and varied stakeholders. NEWT is a community of dedicated and passionate individuals motivated to protect human life through the next generation of water treatment systems. The NEWT Alliance includes four academic institutions – Rice University, Arizona State University, University of Texas–El Paso, and Yale University. With its headquarters at Rice University, this National Science Foundation Engineering Research Center has been discovering new state-of-the-art materials that catalyze the development of off-grid water purification systems since its inception in 2015.
NEWT focuses on a critical part of the solution by developing water technology that is more efficient and decentralized. Many future water systems must be decentralized to avoid significant capital costs and use resources more wisely. Water systems will also need to be smaller and easily installed in off-grid locations. NEWT filtration devices are point-of-entry, making it possible for people to filter water in their homes with smaller, more powerful, and less expensive units that are easier to deploy. These systems can meet multiple fit-for-purpose needs, from providing people with drinking water to delivering ultrapure water for the semiconductor industry.
NEWT’s trailblazing scientists work with matter at a near-atomic scale. This scale allows for developing “fit-for-purpose” water filters, a much cheaper and less wasteful method to filter water. Pollutants of concern are filtered precisely and efficiently without the cost and waste associated with traditional filters that tackle all the elements in water comprehensively, including the ones that are not hazardous or beneficial. NEWT imagines a future where human activity is more beneficial to communities and the planet. Nano-enabled water systems will allow the recycling of valuable nutrients and metals in water.
NEWT is a one-stop shop research center that works to develop new water systems from the ground up. NEWT members are experts in every stage of water system development and design. From thinking through the fundamental aspects of technology design to engineering the components necessary to build systems—NEWT can develop unique technologies and ensure they work. These systems undergo techno-economic analysis and evaluation to examine costs, benefits, risks, and uncertainties.
The overarching, cross-cutting research theme for the NEWT center is safety and sustainability. NEWT conducts life-cycle assessments and undergoes certification processes through the National Sanitation Foundation (NSF) and the Food and Drug Administration (FDA) to ensure technologies are safe for people and the communities they serve. Technical, societal and regulatory barriers are part of the review process for each project. To this end, NEWT teams study technology impacts, acceptability and appropriateness for a wide range of populations and communities that are potential users of NEWT solutions.
NEWT’s efficient modular water purification systems are:
- Easy to set up and can tap unconventional sources to provide humanitarian water or emergency response.
- Cost-effective, efficient, and recyclable.
- Developed to be accessible to those who need it most, especially people in poor rural communities.
- Able to support industries that need to filter and recycle wastewater.
NEWT’s scientific and collaborative outcomes include:
Spearheading research to fight persistent and pervasive “forever chemicals” in water
NEWT has led efforts to efficiently and thoroughly remove harmful PFAS chemicals from water using the sun’s plentiful ultraviolet light and hardened crystal compounds. These types of photocatalytic degradation filters also make filtration cheaper by reducing the number of expensive materials needed to build them, allowing NEWT to transform the economics of water treatment.
Wielding solar energy to make drinking water from the sea
NEWT is finding ways to filter ocean water efficiently, the water we have plenty of. NEWT has partnered with the U.S. Department of Energy to devise ways to desalinate water off-grid. NEWT uses efficient membranes to capture vapor from salt water. Membrane technology reduces energy costs and provides better efficiency when compared to traditional methods, providing water wherever needed.
Protecting human life through sewage treatment
NEWT is working with the Bill and Melinda Gates Foundation to improve greywater treatment. NEWT research and development of point-of-source treatment of urine and greywater will help address the sanitation needs of disadvantaged populations globally. The center has also built prototypes at Yale University to demonstrate NEWT water treatment technologies for humanitarian use. The vision is to install the units with the United Nations to provide solar water disinfection in small ecological dwellings (3.6 billion people lack safe sanitation).
Helping make industrial activities cleaner
NEWT also develops systems to treat and reuse industrial wastewater in remote locations. These systems are making energy production more sustainable with less water footprint. The NEWT systems also increase efficiency by controlling fouling and scaling in industrial water systems.
