The key to perfecting water reuse? continued
The project did establish that the technology would be extremely cost effective for very large wastewater treatment plants that treat volumes in excess of 100 million gallons a day, Pillai said. “If one of those large plants decided to use this technology, the economic model says it is far cheaper than anything else around,” he said. “But the problem we have is that there are not machines that are being designed to treat that volume of water. That is why this technology has not moved forward. “There needs to be more research and development to build a type of machine that can be put into wastewater plants,” Pillai said. “There is currently no machine that is powerful enough.” He said the project has had an impact both regionally and nationally. Engineers from the city of Dallas have performed test runs with their water samples using the eBeam technology, and the city is currently exploring the possibility of adopting the technology in its operations. The U.S. Department of Energy “Accelerators for America” program is exploring the use of linear accelerator technologies for environmental applications.

If eBeam technology is to be used for water treatment, Pillai said it will create a paradigm shift. “One of the big goals in using electron beam is to make transformational changes in how to treat water,” he said. “Having this technology in the ‘tool-box’ Title: Significant Expansion of of water reclamation technologies would Water Reuse Using Electron Beam (eBeam) Technology open up innovative, high-value, commercially viable and environmentally sustainable Principal Investigator: solutions and strategies for water reuse.” Suresh D. Pillai This project was funded by a joint Texas A&M AgriLife Research, Texas A&M Engineering Experiment Station and Texas A&M AgriLife Extension Service Water Seed Grant: Creation and Deployment of Water-Use Efficient Technology Platforms. In 2013, the Texas Legislature charged the agencies to address the critical nexus for water-use efficiency as part of addressing the future water needs of Texas.
