The Rosedale Model 8302P or Model NCO8135Stainless Steel Housings

The Model 8302P and NCO8135 high-capacity filters offer an exceptional value in Giardia Cryptosporidium Removal applications. The system is approved for use in Colorado and Oregon and has met all the EPA LT2 guidelines.

Each housing provides large containment capacity combined with a rugged design rated to 150 psi. It incorporates an eyenut cover that is easily removed, reducing time spent on cartridge change-out.

Features• NSF 61 listed

• Low pressure drops

• Permanently piped housings

• Covers are O-ring sealed

• 304 stainless steel construction

• All housings are electropolished to

resist adhesion of dirt and scale

PS-740-PPP-356 Filter CartridgeMaximize dirt-holding capacity and meet LT2 requirements

PS-740-PPP-356 elements are manufactured in a unique "Y" pleat arrangement that optimizes physical size and maximizes effective surface area. The large surface area provides a low fluid flux rate maximizing dirt containment.

The element fits into the Rosedale NCO8135 housing or can retrofit 8302P housings with an adaptor basket. The end caps are heat sealed for high efficiency performance. The o-ring seal insures sealing and eliminates bypass.

Features• 100 sq. ft. of surface area maximum

• 11 lbs. (approx.) of dirt carrying capacity

• 2 log cryptosporidium credit

• Flow rates to 10 gpm

• 6.25-inch diameter and 35-inch length

• Fits into standard Rosedale Model NCO8135

and 8302P

• Double o-ring seals

• NSF 61 listed

Retrofit Current SitesExisting installations using the Rosedale 8302P and PS-520-PPP-241 or GLR-PO-825-2 can easily convert to a single housing by installing the PS 740 adaptor basket.

This is accomplished by replacing the perforated filter basket with the adaptor. The solid side basket accepts the new PS 740 cartridge and directs the flow through the unit.

PS-520-PPP-241

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-825-2 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.

GLR-PO-825-2

Pre-Filter

PS-520-PPP-241

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.

Final Filter (2 Choices)

1–The Rosedale GLR-PO-825-2 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 bypass-proof 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 "Y" pleat arrangement that optimizes physical size and maximizes effective surface area. The large surface area provides a low fluid flux rate maximizing 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.
