Desalination
The most asset-intensive water treatment process in the world
Desalination turns challenging source water into a dependable supply. Every treatment step depends on measurements that protect membranes, optimize performance and confirm finished water quality.

Turning seawater into a resilient water supply
Reverse osmosis desalination is a connected system. Source water conditions determine pretreatment needs; pretreatment protects the membranes; membrane performance shapes post-treatment; and finished water must remain stable through distribution.
Reliable process data gives operators the confidence to respond before water quality changes become asset damage, production loss or compliance risk.
Process control
Measurement protects the process
The right measurement strategy connects laboratory verification and continuous online monitoring.
- Detect source water changes early
- Optimize chemical dose and pretreatment
- Protect reverse osmosis membranes
- Confirm recovery and salt rejection
- Stabilize and verify finished water
