OSMOTEC "BW 2000 - 15000"
Foreword
The "OSMOTEC BW" reverse-osmosis system is used to reduce the salinity
of brackish well water, with a maximum saline content of 8,000 mg/l (TDS, Total Dissolved Solids).
The "OSMOTEC BW" system requires pretreatment depending on the chemical analysis of the raw water. The
rates of flow and the characteristics of the water produced may vary according to the number of parameters of the
raw water (temperature, T.D.S., etc.).
Under standard conditions of use (featured in the relevant table), the saline content of the water produced is
lower than 500 mg/l.
