2 Rosedale offers the Giardia Cryptosporidium Reduction Filter System for drinking water systems. It is approved in Alaska, California, Washington, Oregon, Vermont, Maine, and Minnesota. Giardia Cryptosporidium Reduction Filter System Rosedale has developed an effective water filtration system that meets the SWTR and protocols for most states. This system offers a dual-stage design that filters out larger contaminants before filtering out micro-organisms. The system consists of two high-quality Rosedale Model 8 housings (pressure vessels), placed in series. The first stage is fitted with a PS-520-PPP-241 bag/cartridge. The second stage is Rosedale's GLR-PO-825-P2 bag/cartridge. This provides a 2 LOG cryptosporidium credit when used in tandem. The optimum flow rate for the system described is 13 gallons per minute (GPM). Rosedale manufactures filtration systems for larger applications, that can filter water up to 500 GPM. Multiple designs are available to meet your needs.

3 Rosedale's Cyst Reduction System offers high efficiency and long life through the effectiveness and quality of its materials and construction. Pre-Filter Pre-filter (Optional) All graded-density bags are constructed of nine-layers of polypropylene micro fibers and standard fibers that are variably calendered. Heavy-duty handles are sewn and turned inside out to avoid leakage and enhance their pressure capacities. GLR-PO Final Filter (2 Choices) 1 The Rosedale GLR-PO element has 26 layers of high-efficiency polypropylene micro fiber material, encased in a rigid support cage. The initial layers are pre-filtration levels, while the next several layers filter the cyst pathogen itself. The final barriers prevent any material from migrating into the effluent. All GLR units have a specially designed gasket to assure a bypassproof seal. All seams and joints are heat sealed to prevent leakage. The inside-out flow design traps contaminants on the inside, reducing the possibility of downstream contamination during changeout and simplifying the service process. NSF 61 listed. 2 The PS-520-PPP-241 filters are manufactured in a unique patented pleat arrangement that optimizes its physical size and maximizes effective surface area. Flow channels distribute a steady flow into the element. A low fluid flux rate maximizes dirt containment. This means element life is extended. NSF 61 listed. Rosedale Products' Cyst Reduction system provides easy installation, operation, and maintenance for a cost-effective solution to water treatment not previously realized by high-cost conventional systems.
