Rice researchers find dialysis ‘astonishingly effective’ for treating wastewater

Borrowing from the medical field, the technique can separate substances while achieving minimal dilution

Researchers at Rice University, in collaboration with Guangdong University of Technology, have uncovered an innovative approach to treating high-salinity organic wastewaters — streams containing both elevated salt and organic concentrations — by employing dialysis, a technology borrowed from the medical field.

The Water Technologies Entrepreneurship and Research (WaTER) Institute at Rice University and Yokogawa Corporation of America, a provider of industrial automation and test and measurement solutions, announced today a new partnership in support of modular autonomous water treatment and reuse processes.

Menachem Elimelech, among the world’s leading researchers in energy-efficient desalination and wastewater reuse, will join the Department of Civil and Environmental Engineering (CEE) as the Nancy and Clint Carlson Chair in Molecular Nanotechnology, effective Jan. 1.

Rice University inaugurated a new research center dedicated to per- and polyfluoroalkyl substances (PFAS) Wednesday during a visit to campus by representatives of the United States Army Engineer Research and Development Center (ERDC).

Rice University chemist James Tour has led a research team to develop a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment. The study was published in Nature Communications on July 20.

For 80 years, “forever chemicals” have been used to coat our pots and pans, put out fires and make our carpets resistant to stains, among many other applications.

HOUSTON – (April 29, 2021) – Wind power has a bright future, but what happens when wind turbines power down? A worn blade the length of a football field isn’t easy to recycle.

Rice University engineering students are working on environmentally sensitive strategies to process decommissioned blades for recycling or disposal. The Bladecycle project, based at Rice’s Oshman Engineering Design Kitchen, requires them to think big.

Students at Rice University’s Brown School of Engineering calling themselves “PFAS and PFurious” took four prizes, including first place, in this year’s 31st WERC Environmental Design Contest for their development of a system to remove harmful chemicals from fluids.

HOUSTON – (July 25, 2022) – Rice University chemical engineers have improved their design for a light-powered catalyst that rapidly breaks down PFOA, one of the world’s most problematic “forever chemical” pollutants.

HOUSTON -- (July 7, 2020) -- Rice University chemical engineers found an efficient catalyst for destroying PFAS "forever" chemicals where they least expected.

Rice University professors Pedro Alvarez and Antonios Mikos have been elected fellows of the American Academy of Arts and Sciences, one of the oldest learned societies in the nation.

Building successful, sustainable solutions to our urgent climate and energy challenges means balancing communities’ technical, economic, environmental and social needs. These goals are at the core of Rice’s new Sustainability Institute. Led by Professor Caroline Masiello and executive director Marie-Nathalie Contou-Carrere, the institute’s strategy is to link science and technology, economics and policy, and social sciences and the arts to effect real change.

As part of a ramp-up in Rice’s strategic research aspirations in health care sciences and technologies, data science and machine learning, and energy, environment and sustainability, the Office of Research, led by Vice President Ramamoorthy Ramesh, recently launched several new institutes. Meet the distinguished scholars leading these dynamic institutes and learn more about their goals in this roundup of Rice’s growing research portfolio.

“Clean water can save more lives than doctors,” says Pedro J. Alvarez, the director of Rice’s new Clean Water Technologies Entrepreneurship and Research Institute (WaTER). But the challenge of accessing clean water for all becomes more extreme by the year.

Water scarcity is one of the greatest global crises of our time. Increasing water supply beyond what is available from the hydrological cycle can be achieved by seawater desalination and wastewater reuse. Highly effective, low-cost, robust membrane-based technologies for desalination and wastewater reuse are needed, with minimal impact on the environment. However, progress in current state-of-the-art water purification membranes has been limited.

Rice University chemist James Tour was named to the National Academy of Engineering (NAE), one of the highest professional distinctions accorded “in recognition of distinguished contributions” to the field.

Rice University and the United States Army Engineer Research and Development Center (ERDC) have signed an Education Partnership Agreement in formal recognition of their collaboration as part of a multi-institutional program that provides financial and educational support for students from low-income backgrounds seeking master’s degrees in engineering and related fields.

Rice University has opened five new research institutes and increased funding of existing ones in recent months as part of a broader effort to boost the private university's graduate program under President Reginald DesRoches’ administration.

The Rice Synthetic Biology Institute and WaTER Institute are among the new institutes that create interdisciplinary hubs based off ongoing research, aiming to draw more students, faculty and grant dollars to the fields.

Houston’s water and wastewater system could be more resilient with the development of hybrid urban water supply systems that combine conventional, centralized water sources with reclaimed wastewater, according to a study by Rice University engineers published in Nature Water.

Nine faculty members in the George R. Brown School of Engineering are ranked among the world’s highly cited researchers, including five in the materials science category.

The 2021 Highly Cited Researchers list is a global accounting of scientists who produced the last decade’s most influential papers, compiled by the Web of Science group, a Clarivate Analytics company.

Pedro Alvarez and Antonios Mikos, senior researchers in the George R. Brown School of Engineering at Rice University, have been elected to the Chinese Academy of Engineering.

Construction of the new $152 million, 266,000-square-foot engineering and science building on the engineering quadrangle at Rice is underway.

The facility, on the site of the former Abercrombie Engineering Laboratory, will feature five floors, including laboratories, classrooms, a makerspace, a cafe and a reception suite. It will serve as both a meeting place and a focus on campus for research and technological advances.

This past June, we thought the COVID-19 situation was improving and we would soon return to normal at Rice, only for the Delta variant of the virus to upend our plans.

Despite the horrors of COVID, working from home for close to a year and a half gave families an opportunity to spend more time together, time to reflect and discover things about themselves. I feel I spent much more time with my wife and kids (though I’m not sure how excited about that they have been!).

The Nanotechnology Enabled Water Treatment Center (NEWT), a National Science Foundation Engineering Research Center (ERC) with its headquarters at Rice University, has earned a five-year renewal to continue its work on next-generation water treatment systems.
