Tank count describes layout; treatment tasks determine selection. Two-tank and three-tank systems may use different media and operating arrangements. More tanks are not necessarily better.
Give each tank a task that can be checked
Match objectives, media loading information, and downstream requirements separately, explaining why each stage is needed. Tank color and equipment names do not replace material documentation.
Compare complete scope and maintenance arrangements
Check whether pumps, valves, backwashing, drainage, bypasses, and controls are included. Even with the same tank count, connections, accessories, and maintenance responsibilities may differ.
Before replacing media, confirm whether the task has changed
Recheck raw water and downstream conditions, then check material batches, quantities, and loading records. Existing media may not suit a new water source or objective.
Use stage-specific records to locate changes
Each stage needs corresponding operating and maintenance records so abnormalities can be analyzed together with adjacent stages. "Complete unit normal" alone does not support later review.
Organize information into an inquiry that can be checked
List available documents, missing items, and questions requiring confirmation for this inquiry, using the same equipment or project version. Remove unrelated personal information from site materials first. Retain original sources. Do not enter illustrations or unreviewed inferences as facts.
