Researchers plan to reconfigure trap and zap wastewater-treatment technology to capture and deactivate the virus that causes COVID-19.

Their chemical-free nanotechnology, introduced earlier this year as a way to kill bacterial superbugs and degrade their antibiotic resistance genes in wastewater, would employ graphitic carbon nitride customized at the molecular level to selectively absorb viruses and then disable them by activating nearby catalysts with light.

The team aims to develop a system that is fast, efficient, and reliable under realistic scenarios, says Pedro Alvarez, professor of civil and environmental engineering and a professor of chemistry and of chemical and biomolecular engineering at Rice University.

COVID-19 might be a dress rehearsal for even more lethal infectious diseases that are very difficult to control, says Alvarez, director of the Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment (NEWT).

We need to enhance the capacity and resiliency of multimedia treatment processesespecially air filtration and wastewater disinfectionto protect public health.

SARS-CoV-2 has been found in air ducts, suggesting it could spread through a buildings air conditioning system, and in stool, even from patients who have tested negative for COVID-19, he says.

That suggests it could reach wastewater treatment plants, where it could survive for days.

While the researchers will test their work in the lab on similar but less-virulent strains, they expect their trap-and-zap treatment approach will recognize coronaviruses that cause not only COVID-19 but also MERS and SARS, according to the project abstract.

Support for the work comes from a National Science Foundation (NSF) RAPID grant to develop a novel approach for selective adsorption and photocatalytic disinfection of SARS-CoV-2.
