Plant water, salt, recovery and bypass balance anomalies
Use this when plant water, salt, recovery and bypass balance anomalies is observed but the cause remains unclear. The diagnostic checks measurement and sampling, operating changes, issue location, and key evidence before suggesting likely causes and the next useful check.

You do not need every data point before you begin
The system asks one discriminating question at a time and updates the candidate causes on the right. Answer from current facts; choose unknown or defer a question when the evidence is not available.
- 1
Confirm the issue
Check whether the symptom is reproducible and whether the measurement or observation is reliable.
- 2
Narrow the causes
Continue through operating changes, issue location, and available inspection results.
- 3

Candidate causes, support, counter-evidence, conflicts, and next actions update as you answer.
This tool analyzes information you already have. It does not insert a safety screen or use safety status to stop the diagnosis. If an alarm, leak, or injury is happening now, follow the site emergency procedure directly.

Phase 1 · Data validity
What is the status of the flow diagram for plant/unit boundaries, inflow/outflow, recycle, evaporation, product, sludge, stormwater, and outfalls?
The system asks the question most useful for separating possible causes. Unknown or deferred items are not treated as the opposite conclusion.
