Why water filter? In our public utility company, the available water is treated to make drinking water and passed on to households. The quality of the drinking water is based on limit values for the ingredients, which are intended to ensure human health. However, the economics of the water treatment must also be taken into account. How much effort does it take to filter out certain ingredients? At which point of the tolerance bands am I moving? Do I filter as well as possible or just as well as necessary (taking into account the question of cost)? For which ingredients are limit values set - it is only a fraction of the substances contained in the water. The analysis and elimination of essential substances such as hormones and pesticides is very costly and sometimes simply not possible from an economic point of view. It is therefore an individual decision to pay renewed attention to the available drinking water. We recommend the use of reverse osmosis filtering with subsequent controlled addition of minerals and revitalization by means of turbulence and energizing. Water filtration reverse osmosis What characterizes an osmosis? Put simply, osmosis is a process in which a low-concentration solution passes through a membrane (a type of fine sieve) to dilute the higher-concentration solution on the other side. In reverse osmosis, a solution with a higher concentration (drinking water with impurities, salts, uranium, pesticides, hormones, etc.) is forced through a kind of sieve (the membrane). Since the water molecules are significantly smaller than all other substances, pure water is available behind the membrane. Depending on the filter system, this remains in a tank (e.g. RO6) or can be used directly in the flow process (Pi-Power systems). Sometimes components of remineralization are used (ceolite, sango corals, organic calcium...e.g. in the Pi cartridge), turbulence or the influence of magnetic processes. If the water remains in a tank until it is used (in contrast to direct flow), it makes sense to carry out post-filtration to counteract the formation of microorganisms in the tank. To increase the service life of the membranes, they are regularly flushed free of the retained salts. This creates waste water, but the costs are lower than changing the membrane.
