Don’t worry. The salt is only used to regenerate the system and then rinsed out completely. Only then is the tank available again for ion exchange. So no salt gets into the drinking water.

During softening, calcium and magnesium ions are exchanged for sodium ions. The total mineral content therefore remains the same.

Softening units work according to the ion exchange process. This means that they exchange the hardness forming calcium and magnesium ions, in the water, for sodium ions. This process takes place in the exchange columns.

These columns contain a high-performance resin on whose surface sodium ions are located. When hard water flows through the containers, the hardness forming ions displace the sodium and bind to the resin. The water is softened.

After a certain time, however, the resin is saturated. The device must be regenerated. To do this, the columns are filled with a saline solution, whereby the resin beads are again filled with sodium ions. Calcium and magnesium ions flow out and the resin is ready to use again.

During regeneration, an exchange column can’t provide softened water. If a softening unit only has one such container (so-called single-column units), it is inevitably out of service for a certain period of time. That’s not the case with the units of the JUDO i-soft series and the SOFTwell P and K: they have two exchange columns. If one of them regenerates, the other one simply continues working.

Water reaches earth via precipitation. Before it hits the ground, it is very soft: hardness of rainwater is close to zero.

Then it seeps away and finally collects as ground water. On its way through different layers of earth and rock, it dissolves various mineral salts. The composition of these rock layers determines the hardness of the water. If a large amount of calcium and magnesium salts gets into the water, it becomes hard. This is particularly the case in areas with a lot of limestone or chalk.

A high-quality water softening unit is absolutely hygienical. First of all, salt already has an antibacterial effect with every regeneration.

JUDO softening units also do a lot to ensure maximum hygienein their operation: they produce small amounts of chlorine from the brine, which fights germs with its disinfecting effect. Even if no water has been taken, the plants initiate a regeneration after 4 days.

The dual systems of the JUDO PREMIUM- and PERFORMANCE-LINE work in parallel operation. This means that there is a constant flow through both softener columns, so that there is no stagnation. The capacity of each softener column is fully utilised. Thus the plants offer a maximum of hygiene and safety.

Lime stains on tiles, fittings and glass shower partitions indicate: you have hard water. Softening is recommended if your water has a hardness of approx. 16 °dH or more. Because from this value on, your pipes are also at risk. Calcifications and constrictions can occur, which in extreme cases can even completely block pipes. And that can be really expensive. Softened water protects you from this.

But soft water has many more advantages: Coffee and tea taste more aromatic. You need less detergent and cleaning agents. Your laundry becomes fluffy soft. And above all, you do something good for yourself: soft water gives you an incomparable feelin gon the skin. It counteracts redness and irritation. It ensures that your hair shines more and is easier to style. In short: It turns every shower into a small wellness treatment.

There is no central contact point. However, your water supplier is obliged to provide information about the different degrees of hardness in each supply area. Usually this information can be found on the website of your water or municipal utility. Please note that water hardness may vary from day to day, as your water supplier obtains and mixes water from different sources. In germany there are – depending on the region – water hardnesses between 0.358 mmol/l (2 °dH) * to approx. 7.16 mmol/l (40 °dH).

You can also learn interesting facts about your drinking water after a drinking water analysis in a laboratory. They will inform you about the most important parameters of your drinking water. This also includes the total hardness.

* 1 °dH = 0.179 mmol/l; 1 mmol/l = 5.6 °dH

The unit is installed directly after the protective filter, which in turn is located directly behind the water meter. Our softening units are designed in such a way that they can be installed even in the smallest of spaces: Brine tank and unit can also be installed separately.
