Nitrate Filter Cartridge

Nitrate Filter Cartridge by CRYSTAL QUEST, standard 10"x2.5" replacement filter cartridge for use with many under-sink and countertop systems(see Related Items below) manufactured by CRYSTAL QUEST and a select of other brands. Contains a special macroporous strong base anion and nitrate-selective resin which is specially designed for the removal of nitrates from water for potable processes. The resin has Highest Operating Capacity of any Nitrate Selective Resin Low Pressure drop while maintaining superior kinetics. Nitrate reduction is 90% to 95% and breakthrough is not affected by sulfate levels. The capacity is 5500 ppm of nitrates as CaCO3. To calculate capacity, first calculate the ppm of nitrates as CaCO3, then divide that number into 5500 to get the gallons.

Optimum performance is achieved at 0.5 GPM (gallon per minute). Be aware, that the higher the flow rate, the less nitrates will be removed from water. The cartridge capacity is 8700 ppm of nitrates as NO3. This cartridge can be regenerated using sodium chloride brine. Sodium chloride is generally preferred for regeneration for reasons of cost and efficiency. When available sea water can be used quite effectively. The use of softened water for make up of regenerant and rinse is often recommended to avoid the precipitation of calcium carbonate in and around the CQ-N250 (or any other resin used in this application). Although the precipitation is not particularly detrimental in the short term, the long term effects may include increased resin attrition and leakage of nitrates.
