What to measure during SWRO site acceptance
Build a desalination test plan around representative feed water, measured production and documented controls.

Define the feed and the product before testing
Agree on the test duration, stable operating period, feed envelope and sampling points. Include feed temperature and conductivity, permeate conductivity, product flow and reject flow. Specify how the team will determine whether the water meets its end-use specification. For a facility that needs low hardness, silica or a specific ion limit, an overall TDS value alone may leave part of the duty unresolved.
Check alarms alongside performance
Confirm pump sequencing, minimum-pressure protection, off-spec product routing and recovery after a power interruption. Record which signals are simulated at the factory and which require on-site observation. Verify pressure instrumentation and use a common timestamp so measured flow, conductivity and power can be compared over the same stable period.
Capture the first operating baseline
Hand over a test report that lists measured values, raw water conditions, approved exceptions and follow-up owners. Keep the first normalized operating trends with the membrane and cleaning documentation. Maintenance teams can then compare like-for-like conditions when output or water quality changes months after commissioning.
