Aqualine™ Nitrate Removal Filter Cartridges
The NRC brine regenerable RO polishing will remove virtually all of the nitrates, nitrites and sulphates from tap water or RO product water for approximately 7500 ppm. The NRC is particularly useful as an RO polisher (since membrane rejection of nitrates can be limited) or in waters containing low sulphates. The NRC can be regenerated using sodium chloride brine.
Brine regenerable RO Polishing Filter Cartridge constructed totally of FDA grade materials and media.
- Ideal Uses: RO polisher, or in waters containing low sulphates.
- Media: FDA Grade high capacity anion exchange resin
- Pre-Filter: 100 micron reticulated poly foam
- Post Filter: 20 micron spun-bonded polypropylene
- pH Range: 5-9

| NRC | 10" Cartridge for Std Housing (Old Part No.: H-F1085S) |
*7500 ppm gal | 0.5-0.75 |
*Third party tested to remove 99% of influent nitrates from a 71 ppm (as CaCO) spiked stream from 200 gallons.
Instructions for Regenerating Nitrate Removal Filter Cartridges:
To regenerate: place a second filter housing containing a filter cartridge full of softener salt before the filter housing containing the Nitrate Removal filter so that the water coming out of the salt filter will go to the Nitrate Removal filter.
Run the water very slowly (approx. 0.25 GPM for a 10" filter) through the cartridges until the salt is gone.
Each time the nitrate removal filter is regenerated, approximately 80% of the capacity is restored.
1st regeneration: 80% original capacity for nitrate removal
2nd regeneration: 64% original capacity for nitrate removal
3rd regeneration: 51% original capacity for nitrate removal
4th regeneration: 40% original capacity for nitrate removal
(and so on)
We do not recommend regenerating the nitrate removal filters more than four times.
