図の背後にある意思決定を読み解く。
Keeps the overview at block-flow level.
Distinguishes sludge treatment from treated-water output.
Shows air, coagulant and return sludge entering treatment.
Use this high-level flow to explain major wastewater process streams before P&ID design.
よくある質問
What is a wastewater block flow diagram?
It is a high-level view of major treatment stages and material streams in a wastewater process.
Why are solids shown separately?
Liquid treatment and sludge handling have different outputs, equipment and operating concerns.
Is this a P&ID?
No. A P&ID adds pipes, valves, instruments and control details.
