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.

* 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.
To regenerate:
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.
