Save costs and enjoy more comfort with pure water. Find the right reverse osmosis system for the best water quality in trade and industry.
Reverse osmosis is a process for removing water constituents using a semi-permeable membrane. The necessary feed water pressure is generated with a high-pressure pump (10 to 15 bar). The product of reverse osmosis is called permeate. The yield is 75 to 80 %, based on the raw water feed. This means that 20 to 25 % is discharged into the sewage system as concentrate. The concentrate contains up to 99 % of the water constituents from the raw water.

In a reverse osmosis system, the water is pressed through a membrane at high pressure. This retains unwanted molecules and impurities, which are flushed out via the concentrate.
Salts, minerals and even bacteria are retained - exactly how much depends on the type and condition of the membranes used. Reverse osmosis reduces the conductivity to below 10 µS/cm without additional processes. With additional processes, values below 1 µS/cm can even be achieved.
The use of osmosis water makes sense wherever water of high purity is required to achieve the desired results. Typical areas of application include aquaristics, chemistry, medicine, car washes and dishwashers.
Yes, osmosis water can generally be drunk. However, as it does not contain any minerals, it is not recommended as permanent drinking water. In addition, removing the ingredients also changes the taste of the water.
This depends on the application and the respective throughput. In principle, however, the membranes can be used for several years before they need to be replaced.
As the substances retained by the membrane must be rinsed out, a certain proportion of the supplied water is required for this. Here too, the values vary depending on the type of pre-treatment. On average, however, a water loss of around 25 % must be expected. This means that for 100 l/h of permeate, the system requires an additional 25 l/h for rinsing (concentrate).
Depending on the size of the osmosis system, it is operated with 230 V or 400 V. The main consumer is usually the pump, which pushes the water through the membranes.
