Greening Up Your Waterpark

We're building a large indoor waterpark and want to ensure the facility is as "green" as possible. Do you have any recommendations for filtration systems that can save energy and water?

There's been a great deal of growth in indoor waterparks in the past few years. But as these facilities have increasingly moved indoors, new challenges have arisen in terms of energy and resource efficiency. With their longer seasons, extended hours of operation and large numbers of visitors, indoor waterparks can stretch sand filters to the max. You're smart to consider these issues up front. New products such as UV technology have helped when it comes to issues such as water and air quality, but when it comes to filters, regenerative media filter (RMF) systems have had a huge impact.

Several large waterparks have reported that RMF systems have enabled them to save millions of gallons of water—and tens of thousands of dollars—a year. While sand systems require backwashing every two to three days, discharging thousands of gallons of water per backwash, the RMF systems only need to be dumped once a month for recoating. Along with saving water, you'll be using fewer chemicals and fuel, and you'll be dumping less water into the sewer. In addition to running greener, you'll be running cheaper.

Add it all up, and you're doing a lot to help the environment—as well as your facility's budget. But even better, the RMF system's ability to keep the water cleaner will translate into safer water for your swimmers. The RMF system can filter out particles down to 4 microns, whereas high rate sand filters remove particles in the range of 8 to 10 microns. As people grow more concerned about recreational water illnesses, it becomes more critical to do all you can to improve the quality and safety of your water.
