Dual Stage Giardia Cryptosporidium Removal
Rosedale has developed an effective water treatment filtration system that meets the SWTR and protocols for most states’ water system filtration requirements.  This system offers a dual-stage design that filters out larger contaminants before filtering out micro-organisms.  
  • The water system filtration consists of two high-quality Rosedale Model 8 housings (pressure vessels), placed in series.  
  • The first water treatment filtration stage is fitted with a PS-520-PPP-241 bag/cartridge.  
  • The second water treatment filtration 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.
