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.
