Description
WODARO Nitrate Care 25 is a specialised ion-exchange unit designed for removing nitrates from water. The model uses selective ion-exchange resin and includes 25 l of media, a 10x35 vessel, a 7650 control valve and a 70 l brine tank. The unit's nominal flow rate is 1.0 m³/h.
WODARO Nitrate Care 25 — nitrate removal water filter
Elevated nitrate levels may occur particularly in water exposed to nitrogen fertilisers and ammonia-containing compounds. If a water test identifies a nitrate problem, standard sediment filtration or water softening alone will not solve it.
WODARO Nitrate Care 25 is designed specifically for this application. It uses selective ion-exchange resin to capture nitrates as water flows through the media. The unit can therefore serve as one stage of a complete water treatment system.
How can nitrates be removed from water?
In the unit WODARO Nitrate Care 25 nitrate removal takes place on selective ion-exchange resin. Water flows through a vessel containing 25 litres of media, where ion exchange reduces the nitrate content.
The resin's working capacity is gradually used up, so the media requires periodic regeneration. The manufacturer specifies regeneration with a 30% sodium chloride solution, meaning a salt solution. The unit uses a separate brine tank for this purpose.
For the unit WODARO Nitrate Care 25 the specified provision is a 70-litre salt tank. According to the technical specifications, the resin may have a service life of up to 10 years with correct operation and periodic regeneration.
What is WODARO Nitrate Care 25 used for?
The unit is intended for installations where water analysis has confirmed a need for nitrate reduction. It can operate as a separate treatment stage or as part of a more extensive water treatment system.
WODARO Nitrate Care 25 can be used, for example, after iron removal and water softening. This is particularly relevant when the water has several different problems requiring successive specialised treatment stages.
Key benefits of WODARO Nitrate Care 25
- specialised application — the unit is designed to remove nitrates from water,
- selective ion-exchange resin — media selected for nitrate reduction,
- 25 litres of media in a 10x35 filter vessel,
- flow rate of 1.0 m³/h,
- brine regeneration — the resin is periodically regenerated with a sodium chloride solution,
- 70 l brine tank matched to this version of the unit,
- can be used as one stage of an extensive water treatment installation,
- stated resin service life of up to 10 years with correct operation.
WODARO Nitrate Care 25 as part of a water treatment system
When water requires several treatment stages, the correct sequence of individual units is important. WODARO Nitrate Care 25 addresses one specific problem — nitrates in water — so it should not be treated as a replacement for an iron removal filter, softener or other equipment intended to remove different contaminants.
If water testing identifies elevated iron content, high hardness and nitrates together, the unit can be installed as a subsequent stage after iron removal and softening. The final installation layout should nevertheless reflect actual water parameters and the required flow rate.
Important: WODARO Nitrate Care 25 is designed to remove nitrates. The unit is not intended to remove nitrites. Where nitrite reduction is required, an appropriately selected RO filtration system is used.
Media operation and regeneration
The ion-exchange resin inside the unit requires periodic regeneration using a sodium chloride solution. A separate tank for salt and brine is therefore provided alongside the unit.
The resin may have a service life of up to 10 years, but this does not mean maintenance-free operation. It must be regenerated regularly to restore ion-exchange operation and remove nitrates from water flowing through it.

FAQ
Does WODARO Nitrate Care 25 remove nitrates from water?
Yes. It is a specialised ion-exchange unit for nitrate reduction, containing 25 litres of selective ion-exchange resin.
Does the unit also remove nitrites?
No. WODARO Nitrate Care 25 removes nitrates, not nitrites. Where nitrite reduction is required, an appropriately selected filtration system should be used, for example one using reverse osmosis.
Does WODARO Nitrate Care 25 require salt?
Yes. The ion-exchange resin requires periodic regeneration with a 30% sodium chloride solution. The unit uses a 70-litre brine tank.
What is the flow rate of WODARO Nitrate Care 25?
The unit's flow rate is 1.0 m³/h. Installation design must also take account of supply pump parameters and the water flow required in the building.
Where should WODARO Nitrate Care 25 be installed?
The unit can form one stage of a water treatment installation, for example after iron removal and softening. The exact sequence of units should be determined from water test results.
How long can the ion-exchange resin operate?
The resin may have a service life of up to 10 years. It nevertheless requires periodic regeneration with a salt solution and appropriate operating conditions.
