Test Rig¶
The test rig is separate from the treatment machine itself. Its job is to compare modules and procedures under controlled conditions so changes are based on data instead of memory.
Use Cases¶
- compare two pumps under the same head and flow conditions
- measure pressure drop across candidate filter housings
- test fouling behavior with different pre-separation strategies
- validate alarms and control thresholds before field deployment
Rig Requirements¶
- stable feed reservoir
- repeatable plumbing geometry
- simple isolation valves
- instrument mounts for temporary sensors
- a logging sheet or digital logger that captures each run
Recommended Run Record¶
| Field | Example |
|---|---|
| Test ID | TR-2026-03-13-01 |
| Source water | pond water after coarse screening |
| Module under test | 5 micron sediment cartridge |
| Starting pressure drop | 1.2 psi |
| Ending pressure drop | 4.8 psi |
| Flow rate | 2.1 L/min |
| Observation | visible fouling by fine clay, no leaks |
Bias to Avoid¶
Do not compare modules under changing source water without noting it. Test rigs only help when the conditions are captured honestly.
