How long can an osmosis system be left idle or not used?

Once an osmosis membrane has come into contact with water after manufacture, it must remain "wet or in the water" permanently. Incidentally, it also needs a few days or several thousand liters of running performance until it is completely "swollen" and thus fully "there" in terms of volume output per hour and also conductivity (water quality). If this membrane were to dry out, it would generally no longer be usable. For this reason, most systems are designed so that the membrane housing is full of water even when switched off or not in use.

This water, in turn, can "tip over" over time or bacteria can multiply in the water if it is not replaced. This proliferation of germs and bacteria can damage the membranes. Accordingly, membrane systems must be used regularly and the residual water in the membranes must be replaced from time to time.

This is usually done by briefly switching on and flushing the machines.
Depending on the manufacturer's specifications and the design of the osmosis systems, this must be done every 4-12 weeks. Basically, it is also possible to preserve membranes with appropriate preservatives. As this process is quite time-consuming and usually has to be repeated after 3 months, we generally advise against this in connection with cleaning work.
