Scrap tires used to filter wastewater

Scrap tires used to filter wastewater
Every year, North America produces millions of scrap tires that clog landfills and become breeding areas for pests. Finding adequate uses for castoff tires is a continuing challenge and illegal dumping has become a serious problem.

Dr. Yuefeng Xie, associate professor of environmental engineering at Penn State Harrisburg, has recently developed a method that uses crumb rubber to filter wastewater, which can help ease the tire problem and clean up the environment at the same time. “My research has found that crumb rubber, derived from waste tires, can be used as a filter media,” Xie explains. “The crumb rubber could be used for treating wastewater, ship ballast water, and storm water.” Crumb rubber is produced by chopping Every year, North America produces millions of scrap tires that clog landfills and become breeding areas for pests.

Dr. Yuefeng Xie, associate professor of environmental engineering at Penn State Harrisburg, has recently developed a method that uses crumb rubber to filter wastewater, which can help ease the tire problem and clean up the environment at the same time. “My research has found that crumb rubber, derived from waste tires, can be used as a filter media,” Xie explains. “The crumb rubber could be used for treating wastewater, ship ballast water, and storm water.” Crumb rubber is produced by chopping filter rates while performing similarly to other media now in use. The crumb rubber media provide better effl uent qualities and larger media allow longer filter runs at higher fl ow rates.

Also a Professional Engineer, Xie holds a U.S. patent on the technology. With more than 20 years of research experience in water and wastewater treatment, he currently focuses his work on water disinfection, disinfection byproduct control, water reuse and acid mine abatement.
