GRF® Condensate Polishers
Graver’s GRF® Condensate polishers are a proven solution for treating condensate for reuse as boiler feed water and reduce the need for fresh makeup process water. In addition, GRF prevents contamination risks within the production cycle which could result in loss of boiler efficiency and possible mechanical damage to key components. GRF® Polishers remove corrosion products such as iron, copper and other metal oxides as well as dissolved solids from the steam condensate, including hardness (calcium/magnesium) and other multi-valent cations resulting in efficient maintenance of boiler water quality.
Typical Applications:
- Polishing for removal of CRUD and TSS to extend boiler service life
- Used to treat in boiler condensate for steam generators and various industrial processes
What GRF Does
GRF® typically functions as a sodium cycle ion exchanger which removes hardness that creates scale deposits on downstream equipment. GRF is effective at temperatures up to 300° F using specially processed cation resins that have been selected for their ability to withstand this high temperature without degradation. In addition, the GRF functions as a filter that removes suspended solids called crud and is designed to utilize the entire depth of the resin bed, resulting in long run lengths.
Regeneration: Regeneration is accomplished either internally (typical) or externally. Chemical regeneration of the ion exchange resin is typically accomplished using salt brine and available in amine or ammonia cycle option upon request. Frequency of regeneration is determined by solids load and flow rates.
Underdrain System: The Graver underdrain system, incorporating stainless steel Partilok® Strainers, assures uniform collection and distribution of water during both service and regeneration cycles. These strainers utilize self-cleaning venturi slots, designed for low headloss and high jet velocity during backwash. Testing equivalent to over 16 years of use indicate no effect of wear, fatigue or decrease in particle retention capabilities. Our standard subsurface washer effectively cleans the bed of accumulated crud.installation and removal.
