エンジニアリングの根拠

方法

原水流量と返送流量を分けて水理負荷を計算し、入力された返送率、有効溶解空気濃度、固形物量から放出空気質量と気固比を算出します。接触時間は名目容量/流量のスクリーニングであり、滞留時間分布や除去保証を示しません。

Recycle flow = recycle fraction × raw flow. Total hydraulic flow includes raw plus recycle.

Raw-flow surface loading uses raw flow; total hydraulic loading uses raw flow plus recycle flow.

Released-air mass = recycle flow × user-entered effective released-air concentration, with mg/L converted to kg/m³. Air-to-solids ratio = released-air mass / entered solids mass basis.

Contact-time screening uses raw flow plus recycle flow through the entered contact/separation volume. Calculated contact time = volume / total hydraulic flow.

範囲 / 制限事項

指定入力から循環流量、原水および総水理負荷、放出空気量、A/S 比を計算します。固形物量と接触槽容積の基準は任意で追加できます。
Calculated hydraulic contact time is a nominal volume/flow screening value and does not represent actual residence-time distribution.
Effective released-air concentration is user-entered. This version does not derive saturator performance from pressure, temperature, or Henry law.
The air-to-solids ratio is a design-basis ratio and is not an adequacy, optimization, or solids-removal guarantee.
This screening tool does not predict bubble size, perform CFD, select recycle pumps, or guarantee solids-removal performance.
