Nitrate Removal Filters
The NRC brine regenerable RO polishing will remove virtually all of the nitrates and sulphates from tap water or RO product water for approximately 7,500 ppm gallons. 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.
These filter cartridges will work in most 10" standard filter housings.
ART NRC Nitrate Removal Filter Cartridges Ordering Details
| Model No. | For Use in Housing | Service Flow (GPM) | Capacity |
|---|---|---|---|
| NRC | 10” Standard | 0.5 – 0.75 | 7,500 ppm gal* |
* Third party tested to remove 99% of influent nitrates from a 71 ppm (as CaCO) spiked stream for 200 gallons. Capacity of the NRC cartridge is approximately 7500 ppm. To determine gallons, divide 7500 ppm by the total ppm of nitrates plus sulphates (as CaCO) to be removed. The result is the number of gallons that can be treated with complete nitrate/sulphate removal.
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
We do not recommend regenerating the nitrate removal filters more than four times.
