The Aquano 10" Nitrate Reduction Water Filter Cartridge is a speciality drinking-water filter designed to reduce nitrates using macroporous resin filtration.

With a 5 micron rating and maximum flow rate of 3 L/min, the NRC1 is designed specifically for low-flow drinking-water applications, making it ideal for installation on a dedicated filtered drinking-water tap.

Unlike conventional disposable treatment media, the nitrate-reduction resin can be regenerated by soaking the cartridge in salty water for 15 minutes, helping extend its useful service life.

Why Choose the Aquano NRC1?

Targeted Nitrate Reduction

Rather than using a general-purpose carbon or sediment media, the NRC1 uses macroporous resin specifically for nitrate removal.

This makes it a useful speciality cartridge where nitrates are the particular water-quality concern being addressed.

Regenerable Filter Media

One of the key advantages of the NRC1 is its ability to be regenerated.

The cartridge can be immersed in salty water for approximately 15 minutes to regenerate the resin to almost-new condition.

This allows the nitrate-removal media to be restored rather than simply discarding the cartridge once its treatment capacity has been reached.

Designed for Drinking Water

With a maximum flow rate of 3 litres per minute, the NRC1 is designed for low-flow applications rather than high-flow whole-house filtration.

It is particularly well suited to supplying a dedicated filtered drinking-water tap.

How It Works

The NRC1 uses macroporous resin to remove nitrates as water passes through the cartridge.

The resin provides targeted nitrate treatment while the cartridge also carries a 5 micron filtration rating.

Over time, the resin's nitrate-removal capacity becomes exhausted. The cartridge can then be regenerated using a salt-water solution, restoring the resin close to its original condition for continued use.

This combination provides:

Nitrate Reduction + 5 Micron Filtration + Regenerable Media

Nitrate Reduction

Nitrates are dissolved compounds that can be present in water supplies, particularly in areas affected by agricultural activity, fertilisers, wastewater or other sources of nitrogen.

Because nitrates are dissolved in water, conventional sediment filtration alone is not designed to remove them.

The NRC1 instead uses specialised macroporous resin for targeted nitrate reduction.

7,500 ppm Nitrate Removal Capacity

The NRC1 has a stated nitrate removal capacity of 7,500 ppm.

Treatment capacity and water flow are different specifications:

Maximum Flow Rate: 3 L/min
Nitrate Removal Capacity: 7,500 ppm

Actual operating life between regenerations will depend on the nitrate concentration in the incoming water and the volume of water being treated.

Higher nitrate concentrations or greater water consumption will use the available treatment capacity more quickly.

Regenerable Macroporous Resin

A major advantage of this cartridge is that the nitrate-removal resin can be regenerated.

The process involves immersing the cartridge in salty water for approximately 15 minutes.

This regenerates the resin to almost-new condition so that it can continue providing nitrate reduction.

This makes the NRC1 different from many replacement cartridges that are simply discarded once their treatment media is exhausted.

Best Suited For

The Aquano NRC1 is particularly suited to:

• Nitrate reduction
• Drinking-water filtration
• Dedicated filtered drinking-water taps
• Low-flow filtration systems
• Underbench drinking-water systems
• Point-of-use filtration
• Water supplies where nitrate reduction is required
• Customers wanting regenerable nitrate-treatment media

Key Specifications

Why the 3 L/min Flow Rate Matters

The NRC1 is a speciality treatment cartridge, so its maximum flow rate is considerably lower than a conventional sediment or carbon cartridge designed for higher-flow applications.

The 3 L/min maximum flow rate allows water to pass through the specialised resin at a rate suited to nitrate treatment.

This makes the cartridge particularly appropriate for a dedicated drinking-water tap, where high whole-house flow rates are unnecessary.

Compatibility

The NRC1 is a 10" replacement water filter cartridge designed for compatible filtration systems capable of operating at its required low flow rate.

It is particularly suited to point-of-use drinking-water filtration installations.

Before replacing an existing cartridge, check:

• Cartridge size
• Housing compatibility
• Available flow rate
• Existing filtration configuration
• Intended application

For nitrate treatment, the system should be configured so water passing through the NRC1 remains within its 3 L/min maximum flow rate.

Installation

The NRC1 can be installed into a compatible serviceable filter housing as part of a suitable drinking-water filtration system.

For cartridge replacement:

1. Turn off the incoming water supply.
2. Relieve pressure from the filter housing.
3. Open the housing.
4. Remove the existing cartridge.
5. Clean the housing as required.
6. Check the housing O-ring is correctly seated and in good condition.
7. Install the NRC1 cartridge.
8. Reassemble the housing.
9. Slowly restore the water supply.
10. Check carefully for leaks.
11. Flush the filtration system before drinking the treated water.

Ensure the filtration system is configured for the cartridge's maximum flow rate of 3 L/min.

Maintenance & Regeneration

The Aquano NRC1 can be regenerated rather than immediately replaced when its nitrate-treatment capacity becomes exhausted.

Regeneration

The cartridge can be regenerated by:

Immersing it in salty water for approximately 15 minutes.

This process restores the nitrate-removal resin to almost-new condition.

The frequency of regeneration will depend primarily on:

• Nitrate concentration in the incoming water
• Volume of drinking water treated
• Overall water quality
• Frequency of use

Because nitrate levels cannot be reliably determined by the appearance, taste or smell of water, water testing is the appropriate way to assess nitrate concentration and treatment performance.

Frequently Asked Questions

What does the Aquano NRC1 remove?

The NRC1 is specifically designed to reduce nitrates from water using macroporous resin.

What filtration media does it use?

It uses macroporous nitrate-reduction resin.

What is its nitrate removal capacity?

The cartridge has a nitrate removal capacity of 7,500 ppm.

What is the micron rating?

The NRC1 has a 5 micron rating.

What is the maximum flow rate?

The maximum flow rate is 3 litres per minute.

Why is the flow rate only 3 L/min?

The NRC1 is designed as a low-flow speciality treatment cartridge for drinking water rather than a high-flow whole-house cartridge.

Can I use it with a dedicated drinking-water tap?

Yes. A dedicated filtered drinking-water tap is one of the NRC1's primary applications.

Can the cartridge be regenerated?

Yes. The nitrate-reduction media is regenerable.

How do I regenerate the filter?

The cartridge can be immersed in salty water for approximately 15 minutes to regenerate the resin to almost-new condition.

How often should I regenerate it?

The frequency will depend on the nitrate concentration of the incoming water and how much treated water is used.

How do I know whether nitrate treatment is working?

Nitrates are dissolved contaminants that cannot be reliably assessed by the water's appearance, taste or smell. Water testing is the appropriate method for checking nitrate concentration.

Is this a whole-house filter?

The NRC1 is designed for low-flow drinking-water filtration with a maximum flow rate of 3 L/min. It is better suited to a dedicated drinking-water application than high-flow whole-house filtration.

Is this a sediment filter?

Its 5 micron rating provides filtration, but the primary purpose of the NRC1 is nitrate reduction using macroporous resin.
