  9. Forever Chemical Gone Forever Using Nanotechnology By Converting PFAS Into Graphene Nanoparticles

    21 Aug 2022 | | Contributor(s):: Robert Garza, Rice University

    Forever chemicals are in a class of chemicals commonly known as PFAS (Per- And Polyfluoroalkyl Substances). These chemicals are found in items such as microwave popcorn and fast food containers. Consequently, they are now being found in drinking water causing health problems such as a...

  10. Designing a System that will Prevent Membrane Fouling in the Event of a Power Outage

    21 Aug 2022 | | Contributor(s):: Enrique Gomez, University of Texas - El Paso, NEWT Center

    This project focuses  on finding a solution to prevent membrane fouling in the CERRO units located at the lower valley plants in the event of a power outage. Power outages are common in the 79907 area of El Paso, Texas especially during the summer season. In the event of a power...

  11. Cleaning Household Greywater for Reuse as Toilet Water

    21 Aug 2022 | | Contributor(s):: Elliot Hall, Arizona State University, NEWT Center

    Freshwater is becoming scarce while we use it as a limitless resource. Roughly 30% of our daily water usage is from toilets. Our project, funded by Gate Foundation is to recycle household greywater, clean it, and reuse it in toilets. In this work, the physical foam fractionation is...

  12. TiO2 Everywhere!

    20 Aug 2022 | | Contributor(s):: Tabatha Schacht, University of Texas - El Paso, NEWT Center

    How much Titanium Dioxide (TiO2) is present in the water we drink? This research focuses on terephthalic acid (TPA) and UV light in order to detect the levels of TiO2 present in drinking water and thus ensuring the levels are within the safe parameters of consumption.

  13. Removal of PFOAS & Nitrate From Waste Water
