Nitrate Specific Cartridge — Reduce Nitrate Levels in Drinking Water
The NC Series Nitrate Reduction Cartridges use Jacobi Resinex NR-1, a nitrate-selective strong-base anion exchange resin specifically designed for the removal of nitrate from drinking water.
Resinex NR-1 provides high nitrate selectivity, including in water containing sulphate, making these cartridges well suited to bore water, rural water supplies and other drinking-water applications where elevated nitrate levels are present.
Unlike disposable nitrate cartridges, the NR-1 media is regenerable using a salt (sodium chloride) solution, allowing the cartridge to be reused over multiple treatment cycles.
Available Options
| Model | Size | NR-1 Media | Flow Rate | pH Range | Capacity as NO₃-N | Equivalent Capacity as NO₃ |
|---|---|---|---|---|---|---|
| NC1020 | 10" × 2.0" Inline | 400 mL | 0.5–3 LPM | 4.5–8.5 | ~3,750 mg | ~16,600 mg |
| NC10-GAC | 10" × 2.5" Standard | 400 mL | 0.5–3 LPM | 4.5–8.5 | ~3,200 mg | ~14,200 mg |
| NC10 | 10" × 2.5" Standard | 700 mL | 0.5–3 LPM | 4.5–8.5 | ~7,500 mg | ~33,200 mg |
| NC10J | 10" × 4.5" Jumbo | 2,000 mL | 0.5–3 LPM | 4.5–8.5 | ~21,000 mg | ~93,000 mg |
Important: Nitrate may be reported on water test results as either Nitrate-N (NO₃-N) or Nitrate (NO₃). Always use the matching capacity column when calculating expected cartridge life.
How to Calculate Treatment Capacity
To estimate the volume of water that can be treated before regeneration:
Cartridge capacity (mg) ÷ nitrate concentration in the water (mg/L) = approximate litres treated
For example, if an NC10 cartridge is treating water containing 5.7 mg/L Nitrate-N:
7,500 mg ÷ 5.7 mg/L = approximately 1,315 litres
If your laboratory report gives nitrate as NO₃, use the NO₃ capacity column instead.
Actual treatment capacity can vary depending on water chemistry, flow rate, competing ions and the required treated-water nitrate level.
Ideal For
- Rural properties with elevated nitrate levels from agricultural activity
- Bore and well water supplies
- Point-of-use drinking water systems
- Homes wanting to reduce nitrate levels in their drinking water
- Applications where a regenerable nitrate cartridge is preferred over disposable media
Regenerable Media
One of the major advantages of Resinex NR-1 is that the media can be regenerated rather than discarded when its nitrate capacity has been exhausted.
Jacobi recommends regeneration using a 5–10% sodium chloride (salt) solution, allowing sufficient contact time for the nitrate ions captured by the resin to be displaced by chloride ions.
After regeneration, the cartridge must be thoroughly rinsed with clean water before being returned to drinking-water service.
The cartridge can then be reused for further nitrate-reduction cycles.
Important Information
Cartridge capacity figures are approximate and are intended as a guide. Actual performance will depend on the nitrate concentration, water chemistry, flow rate, competing anions and operating conditions.
For the best performance, we recommend having your water professionally tested so that the correct cartridge size and expected treatment capacity can be determined.
