The University of Chicago and Ben-Gurion University of the Negev will begin funding a series of ambitious research collaborations that apply the latest discoveries in nanotechnology to create new materials and processes for making clean, fresh drinking water more plentiful and less expensive by 2020.
The announcement came June 23 following a meeting in Jerusalem among Israeli President Shimon Peres, Chicago Mayor Rahm Emanuel, University of Chicago President Robert J. Zimmer, Ben-Gurion University President Rivka Carmi and leading scientists in the field. The joint projects will explore innovative solutions at the water-energy nexus, developing more efficient ways of using water to produce energy and using energy to treat and deliver clean water.
“We feel it is critical to bring outstanding scientists together to address water resource challenges that are being felt around the world, and will only become more acute over time,” said Zimmer. “Our purification challenges in the Great Lakes region right now are different from some of the scarcity issues some of our colleagues at Ben-Gurion are addressing, but our combined experience will be a tremendous asset in turning early-stage technologies into innovative solutions that may have applications far beyond local issues.”
“Clean, plentiful water is a strategic issue in the Middle East and the world at large, and a central research focus of our university for more than three decades,” said Carmi. “We believe that this partnership will enhance state-of-the-art science in both universities, while having a profound effect on the sustainable availability of clean water to people around the globe.”
The first wave of research proposals include fabricating new materials tailored to remove contaminants, bacteria, viruses and salt from drinking water at a fraction of the cost of current technologies; biological engineering that will help plants maximize their own drought-resistance mechanisms; and polymers that can change the water retention properties of soil in agriculture.
One proposed project would attempt to devise multi-functional and anti-fouling membranes for water purification. These membranes, engineered at the molecular level, could be switched or tuned to remove a wide range of biological and chemical contaminants and prevent the formation of membrane-fouling bacterial films. Keeping those membranes free of fouling would extend their useful lives and decrease energy usage while reducing the operational cost of purifying water.
Another proposal focuses on developing polymers for soil infusion or seed coatings to promote water retention. Such polymers conjure visions of smart landscapes that can substantially promote agricultural growth while reducing irrigation needs.
Officials from both the U.S. and Israel hailed the collaboration as an example of the potential for collaborative innovation that can improve quality of life and boost economic vitality.
“Chicago’s worldwide leadership in water management continues to grow, as we invest in our water infrastructure, creating jobs for our residents and economic activity in our neighborhoods. I strongly support this partnership, and I look forward to working with leading institutions like BGU and the University of Chicago to create innovations and opportunities for the future,” said Emanuel.
The Israeli government founded BGU with a mandate to spearhead the development of the Negev Desert. BGU has worked at the forefront of water-related research for more than four decades, having developed several innovative technologies in the field. Work at the Zuckerberg Institute for Water Research has helped make it possible for Israel to produce more than 60 percent of its freshwater needs by desalination.
