Description
WODARO Nitrate Care 40L is a nitrate removal system, equipped with 40 litres of selective ion exchange resin, a BNT 7650 control valve and a 70-litre brine tank. The model has a capacity of 1.0 m³/h and treats water where testing has identified a need to reduce nitrates. It can serve as a separate treatment stage, complementing processes such as iron removal and softening.
Nitrate filter - selection for a specific water problem
If you are wondering how to remove nitrates from well water, the starting point should be a water analysis result. WODARO Nitrate Care 40L is designed specifically for this purpose. It uses selective ion exchange resin, making it suitable for an installation requiring targeted nitrate removal.
This variant is suitable where water parameters, flow requirements and feed conditions meet the requirements of a system with a 1.0 m³/h capacity. Selection should not be based solely on the number of household members – water test results and pump parameters also matter.
Nitrates and nitrites are different compounds. WODARO Nitrate Care 40L is designed to remove nitrates. It should not be selected for nitrite removal or treated as a complete solution to every water quality problem.
Main advantages of WODARO Nitrate Care 40L
- Selective ion exchange resin – media designed to remove nitrates from water.
- Regenerable media – the resin's working properties are restored using a sodium chloride solution.
- BNT 7650 control valve – the component that controls this system variant.
- Separate 70 l brine tank – supplied for this model as part of the regeneration system.
- Suitable for a multi-stage installation – the system can be installed after other treatment processes required for the water source.
How does the nitrate removal system work?
Water flows through a column containing 40 litres of selective ion exchange resin. During contact with the media, nitrates are removed by ion exchange. The resin requires periodic regeneration with brine, a sodium chloride solution, to continue performing its function.
WODARO Nitrate Care 40L can be used as one treatment stage, for example after iron removal and softening. The sequence of units and extent of pretreatment should be determined from the water composition.
Equipment and installation space
The WODARO Nitrate Care 40L configuration comprises:
- a filtration column with a 10 × 54 inch vessel,
- 40 l of ion exchange resin,
- a BNT 7650 control valve,
- a 70 l brine tank.
When planning the space, allow for both tanks. The vessel is 268 mm in diameter and 1381 mm high, while the brine tank is 332 mm in diameter and 880 mm high. The vessel height is not the unit's overall height – the control valve sits above it, and its height is not specified in the datasheet.
The system has 1 inch connections and operates at a pressure of 2–6 bar and a water temperature of 2–30°C. Before purchase, check the feed pump's capacity and head to ensure they meet the unit's requirements.
Operation and resin regeneration
Operation relies on providing salt to prepare brine and periodically regenerating the media. Regeneration settings and frequency should be matched to the system's operating conditions; the datasheet does not specify a single fixed schedule for every application.
The manufacturer states a resin service life of up to 10 years, subject to regular regeneration. This value does not guarantee that service life in every installation or mean that the media can be used without maintenance.

FAQ
Is WODARO Nitrate Care 40L suitable for well water?
It can be used for well water requiring nitrate removal. However, selection must be preceded by water testing and a check of installation parameters. The results may also indicate a need for additional treatment stages.
Does this filter also remove nitrites?
No. According to the datasheet, the unit is designed to remove nitrates. If testing has shown nitrites, a solution suited to that problem is required.
Will the system replace an iron removal filter or water softener?
This model should not be selected as a replacement for an iron removal filter or softener. Its purpose is nitrate removal. The system can operate after iron removal and softening if those processes are needed for the water concerned.
Does the system need salt to operate?
Yes. The resin is periodically regenerated using a sodium chloride solution. WODARO Nitrate Care 40L is equipped with a 70 l brine tank, and a supply of regeneration salt must be maintained during use.
What should I check before buying WODARO Nitrate Care 40L?
Check the water analysis results, required flow rate, pressure and pump capacity and head. Space must also be allowed for the column with its control valve and the separate brine tank. This variant has a capacity of 1.0 m³/h.
