1)
With salt content 500 mg/l, 4 bar, water temperature +15°C, no back pressure. At a lower water temperature, the permeation rate declines.
2)
With concentrations > 0.1 mg/l of free chlorine in the drinking water, the service life of the pre lter must be halved.
3)
The system produces up to 40% less pure water that the nominal  gure in winter, but up to 60% more in the summer.
