Discarded glass bottles are getting another job: filtering water.
Sand and activated charcoal can become fouled over time. John Wilson, CEO of Johnson Screens, explains how recycled glass offers another option for filtration—and an opportunity to reduce biofouling, the buildup of microorganisms on filter media.
The company’s GreenFil media is made from post-consumer green and brown glass bottles and designed as an alternative to conventional sand. Wilson describes two benefits: improving filtration performance and putting discarded material back to work.
It’s a connection between recycling and water treatment that starts with what goes inside the filter.
