High concentrations of nitrates in drinking water can cause serious health problems, especially for infants and pregnant women. Our modern filtration technologies effectively reduce nitrate content without negatively affecting other water parameters, thus ensuring safe water for your family.
Higher concentrations of nitrates in drinking water can cause serious health problems. Nitrates are transformed in the digestive tract into nitrites, which are involved in the formation of methemoglobin and thus in the breakdown of oxygen transfer through the blood. In this context, the most sensitive part of the population are formula-fed infants under 3 months of age, due to the risk of developing (infant) methemoglobinemia. Other sensitive groups are pregnant women and people with metabolic disorders. The reaction of nitrites in the stomach with some food components can produce cancer-causing nitrosamines. In addition, other possible health effects of nitrate intake have been described in the studies conducted. A person eating a normal diet receives most of their dose of nitrates (and nitrites) through food, especially in vegetables and also in meat products, where they are added as permitted additives. However, with a higher nitrate content in drinking water (above 50 mg/l), even drinking water becomes an important source of nitrates for humans.
Write to usSince there are still many unanswered questions about the effect of nitrates on human health, it is desirable to reduce the population's exposure to nitrates from drinking water to the lowest reasonably achievable level.
Ion exchange technologies are probably the most widespread method for family houses and municipalities. These are filters where (in layman's terms) salt is sprinkled for proper functioning. However, even this technology has its limits. These generally begin to manifest themselves in places where the sum of nitrate and chloride values in the raw water exceeds 100 mg/l.
For cases of unfavorable values of nitrates and chlorides, which prevent the use of classic ion exchangers of regenerated salts, and for more demanding customers on water quality, ion exchanger technologies operating in a mode where there is no increase in chlorides in drinking water are offered. They are also called double-wash filters. These can eliminate the shortcomings of reverse osmosis as well as the limiting limits of ion exchangers regenerated with sodium chloride. Unlike reverse osmosis, they are water-friendly and do not negatively affect other parameters. Compared to ordinary ion exchangers, it removes nitrates better and has a favorable effect on the chloride value.
Write to usMembrane technologies are one of the options for reducing nitrate concentration in drinking water. They can reduce even very high nitrate values. However, their disadvantage is the influence and possible deterioration of other indicators of drinking water. It is mainly calcium and magnesium that do not meet the requirements for drinking water after reverse osmosis. Possible reverse mineralization cannot make up for this deficit in 'under the sink' equipment. Another consequence is a decrease in the pH of the water, which can also be a problem in some cases.

The main factors responsible for the occurrence of nitrates in groundwater are mainly the use of artificial fertilizers, the management of organic waste mainly from agricultural livestock farming and changes in land use. Nitrogen compounds enter groundwater most often through seepage from over-fertilized soil, or from the inadvertent seepage of wastewater from leaky cesspools and sewers. Nitrogen compounds can enter surface water either from treated wastewater discharges, but also from runoff from artificially fertilized or manured fields and meadows as a result of heavy rains.
This is a fairly common question. Infant water must come from a protected underground source and must not be treated in any way, with the exception of UV disinfection. This water is suitable for preparing baby food and for continuous direct consumption by all groups of the population,
In practice, this means that treated water may not be labeled as baby water, but it can meet the parameters of baby water.
The most widespread method of reducing nitrate concentration in water is ion exchange technologies. With regard to economy and simplicity of operation, they are regenerated with sodium chloride. By replacing some types of ions (not only nitrates) with sodium chloride, there will be an increase in chlorides in the treated water. The problem cannot be avoided by substituting sodium chloride for another salt (without chlorides), however, we offer a solution developed by us that can eliminate this problem and, in addition to nitrates, also adjusts the chloride value. We offer these devices from the smallest filters for one faucet, through home treatment plants to corporate and municipal solutions.
