Osmosis filter
Differential pressure measurement in an osmosis filter
|
|
Process data
Measuring task:
Differential pressure measurement
Measuring point:
Filter
Measuring range up to:
+20 bar
Medium:
Sea water
Process temperature:
0 ... +25°C
Process pressure:
0 ... +20 bar
Special challenges:
Resistant to sea water
Application
Sea water is pressed through a semi-permeable membrane under high pressure. The semi-permeable membrane allows only water molecules to seep through. Salts, bacteria and viruses are retained in the filter. The finished product is almost the same as distilled water. A differential pressure measurement is needed to monitor the level of contamination across the filter.
Your benefit
Reliable
Approved materials according to FDA and EC 1935/2004, as well as local certification
Cost effective
Efficient cleaning of the filter is possible even during continuous operation
User friendly
Maintenance-friendly thanks to front-flush mounting
