Nitrate filter – clean water despite nitrate contamination
What is nitrate and why is it problematic?
Nitrate is a nitrogen-containing compound that occurs naturally in the soil but enters the groundwater in large quantities due to intensive agriculture, manure application, and fertilizers. Especially in rural areas, drinking water often exceeds the legally established limit of 50 mg/l nitrate.
Health risks from nitrate in drinking water
When nitrate is absorbed in the body, it can be converted into nitrite. This blocks oxygen transport in the blood and can lead to the so-called "blue baby syndrome" (methemoglobinemia), especially in infants. Adults should also not consume too much nitrate permanently, as nitrite and the resulting nitrosamines can be carcinogenic.
How does a nitrate filter work?
A nitrate filter reliably removes nitrates from the water – either through anion exchange or biological denitrification:
Anion exchange: Here, nitrate ions are exchanged for harmless chloride ions. After a certain capacity, the filter is regenerated with a saline solution.
Biological denitrification: Bacteria convert nitrate into gaseous nitrogen. They require a carbon source such as alcohol or paraffin beads for this.
Advantages of a nitrate filter in the household
Healthier drinking water: Reduction of nitrate contamination to a safe level.
Ideal for private wells: Especially important for households with their own well.
Sustainable solution: Less plastic bottles, no need to buy water.
Tap water or bottled water?
Tap water is strictly controlled in Germany – however, nitrate contamination can still occur in some regions. A nitrate filter ensures consistently high water quality directly from the tap. This not only saves money but also protects your back and the environment: no carrying, no waste.
Who is a nitrate filter especially useful for?
Households with their own well or from regions with nitrate problems.
Families with small children or infants.
People with increased health awareness or sensitive metabolism.
Conclusion: Safe water thanks to nitrate filter
A nitrate filter is an effective and proven solution to remove nitrates from drinking water and protect your health in the long term. Whether for private households or to support your own well – with a suitable filtration system, you reliably reduce nitrate and enjoy pure water without risk.
