Magnesium and calcium are vital minerals that we must obtain through food — for example through our drinking water. In many places, the minerals are already contained in tap water. The disadvantage: Calcium and magnesium can combine with other substances and form calcium deposits. This makes your healthy water a potential hazard for your household appliances such as washing machines and dishwashers or boilers. Lime in the water also leaves annoying white deposits on faucets. A water softening system in an apartment building can prevent these problems. We'll let you know about your options.
Water treatment through water softening for apartment buildings makes sense when there is a lot lime in drinking water — that is, when the water is “hard.” Hard water is referred to as soon as the water exceeds a degree of hardness of 14 °dH (degree of German hardness). If you are supplied with hard drinking water in your residential area, you will quickly notice this in the typical calcium deposits in the bathroom and kitchen. If you want to determine your exact water hardness, you have two options: You can get test strips yourself and measure the water hardness. The strips are available at pharmacies, drugstores or online. Alternatively, you can check with your regional water supplier or waterworks about your water hardness. The information can usually be found on your provider's website.
The most reliable way to reduce the lime content in water is to water softener. There are various technologies here to combat lime and prevent calcium deposits.
A common method for softening water in apartment buildings is a Water softening system with salt (ion exchanger). During ion exchange, the lime contained in the water is combated with salt (sodium chloride). The salt is fed into the water supply in the form of tablets, and the magnesium and calcium compounds of the lime are replaced by sodium. As a result, the lime is partially removed from drinking water. The calcium and magnesium levels of the water fall and the sodium content rises.
lookout: According to the German Drinking Water Ordinance, the maximum sodium content in water is 200 mg/l. Since the sodium content always increases when softening water with salt, it is essential to pay attention to how much sodium is in drinking water before softening. 8.2 mg sodium is required to soften one liter of drinking water by 1 °dH. Even if the initial sodium value of your drinking water is zero, the water can be softened by a maximum of 24.4 °dH before the maximum permitted value is exceeded.
If the sodium content in your drinking water is too high to soften the water sufficiently with salt, offer Lime protection systems with seed crystal formation is a good alternative. Since no salt is used in these systems, the calcium and magnesium levels of the water also remain unchanged. The original water hardness is retained. In the seed crystal process, microscopically small crystals, so-called seed crystals, are formed in water. The lime that is already in the water attaches to these crystals and no longer sticks to fittings. As soon as you remove water from the tap, the seed crystals are rinsed out together with the accumulated lime.
The requirements for water softening in apartment buildings differ in some respects from those for a Water softener for single-family homes:
AQON PURE home + offers you an innovative solution for treating your tap water by forming seed crystals — completely without salt tablets, without the associated increase in sodium content and without loss of calcium and magnesium. These lime protection systems are suitable for two to four-family houses, as well as significantly larger residential buildings. AQON PURE home + is specifically tailored to the higher water consumption and flow rates in apartment buildings and provides you with an output of up to 75 liters per minute. The descaling system can be used from a total water hardness of 5° dH and has a lifespan of up to 20 years. If you opt for an AQON PURE water softening system for your apartment building, you will also receive a one-year money-back guarantee and the option of having the system installed by a fitter near you at a fixed price.
