Bestseller No. 6
Nitrate Removal Filter Cartridge | 2-7/8" x 9-3/4" | CQE-RC-04007 | Crystal Quest
  • Nitrate (NO3) comes into water supplies through the nitrogen cycle rather than via dissolved minerals. It is one of the major ions in natural waters. Most nitrate in drinking water is the result of contamination of groundwater supplies by septic systems, feedlots, and agricultural fertilizers. Nitrate is reduced to nitrite in the body.
  • These cartridges contain a special nitrate-selective resin. Nitrate reduction is 90% to 95% and breakthrough is not affected by sulfate levels.
  • Important Note: The cartridge(s) in this system require manual salinity regeneration. The media must be recharged in order to maintain optimum performance. If the media is not regenerated, then the media will exhaust and result in a permeate of 0. The cycle of regeneration will vary based on the influent level of contaminants.
  • The process of regeneration involves dissolving salt in water (2-3 cups of salt for every 3-4 cups of water) stir well and soak (you may want to use something to hold the cartridge down) the cartridge for 1-2 hours, then soak the cartridge in tap water for an additional 1-2 hours, rinse with the tap running tap water and reinstall the cartridge. Regeneration is not required before its first use even if the cartridge has been unopened for a period of time.

  • CATION & ANION RESIN: The mixed bed resin is composed of cation resin and anion resin (H+ and OH-) in the ratio of 40/60, which is why Resin-Pure can produce extra pure water as a water filter.

Our mixed bed resin for aquarium filters purifies the water to an average conductivity value of about 0.1 μS/cm.
  • APPLICATION: Resin Pure mixed bed resin is ideally suited for use in commercially available resin filters, e.g. in an osmosis system. The demineralizer should be changed whenever the TDS value of the water increases again.
