Defender Filters for Swimming Pools
Defender® Regenerative Media Filters
The Defender® filter is an earth-friendly solution for pristine pool water and it continues to have a marked impact on the global water footprint. This industry-leading filter offers maximum performance, longevity, and user-friendliness — benefits that are good for the planet and our resources.
Fabulous Five benefits enjoyed by Defender® customers
- Water & Waste Savings
The Defender® filter virtually eliminates the tremendous amount of the backwash water associated with sand filter operation. Instead of reverse flushing, as with a sand filter, Defender® simply discharges the spent media directly to waste and is recharged periodically.
- Energy & Chemicals Savings
The significant reduction of backwash waste directly translates to savings in make-up water, chemicals, and fuel for reheating. Consider the cost of chemically treating 2.2 million gallons (8328 m3) and the BTUs (heat units ) required to heat this volume of water from 50 degrees (10°C) to 80 degrees Fahrenheit (27°C).
- Construction Savings
More savings come from the smaller construction footprint for Defender® filter. It needs as little as one-fourth to one-sixth of the space required by an equivalently sized sand system, saving installation and rigging time.
- Power Savings
Defender® reduces head loss compared to sand filters, saving on motor horsepower operational costs. Starting differential pressures for a high-rate sand filter, depending on the media, could range from 4 to 6 psi (27.6 kPa to 41.4 kPa). In contrast, the starting differential of Defender® is approximately 1 psi (6.9 kPa). Converting this to head represents savings of nearly 12 feet (3.65m) total dynamic head (TDH), resulting in horsepower and energy savings. In most cases, the pump motor required for Defender® filter re-circulation is smaller than a sand filter. Utilizing a 25hp motor instead of a 30hp unit would result in electricity savings of $3,000 per year.
- Water Quality
The Defender® filter removes particles down to 1 micron. With the growing concerns about waterborne illnesses (WBI) such as cryptosporidiosis, smaller particle removal is to better. The Defender® filter is especially effective on pools with heavy bather loads due to its increased filter area and dirt holding capacity.
