Rosedale Giardia Lamblia Cyst Removal Filter Bag

Rosedale Giardia Lamblia Cyst Removal Filter Bag

In answer to the stringent Federal Surface Water Treatment Rules now in effect, Rosedale has developed a filter bag certified to remove the giardia lamblia cyst. Giardia is the main cause of camper’s diarrhea and other digestive illnesses. The rule regarding giardia is the 99.9% (3 log) must be removed (2 log through filtration and 1 log through disinfection). The Rosedale Giardia Lamblia Removal (GLR) bag is certified to be 99.95% efficient at 3 microns.

The relative low cost of these bags makes them the ideal solution for smaller water authorities. A single-bag filer housing with a GLR bag can filter up to 20 gallons of water per minute. Using Rosedale’s multi-bag filter housings, it is possible to filter water at up to 500 GPM. These housings can be banked together in parallel, providing even greater throughput. A pre-filter must be installed prior to the GLR housing to filter out larger particles, lessening the dirt-load on the GLR bag. The GLR bags are made of various layers of polyester or polypropylene micro fibers and standard fibers variably calendared to obtain the ratings as shown. This greatly increased the dirt-holding capabilities of these bags.
