Regenerative Media Filters Considered the Wave of the Future

Paul Steinbach Headshot

With their ability to use media over and over again, regenerative filters are considered the wave of the future.

As director of maintenance at Mt. Olympus, Jason Hammond's job is to prevent Poseidon's Rage from spreading Cryptosporidium's Revenge. That's why Hammond relies on four regenerative media filters to keep the pool's 1.5 million gallons of water sparkling and safe. The filters, which employ a milled mineral called perlite as the filter medium, represent a departure for Mt. Olympus, which features sand filters on all of its other water attractions. However, sand filtration on a pool the size of Poseidon's Rage would be impractical, according to Hammond. "We'd have to use between 50,000 and 60,000 gallons of water a day to backwash high-rate sand filters on a 1.5 million-gallon pool," he says. "With the regenerative filters, we only use 5,000 gallons of water every two weeks."
