01 · USER INPUT

Design basis and inputs

Design flow *m³/d · flow through rapid mix and each flocculation stageMust be greater than 0.Dynamic viscosity *Pa·s · explicit water-property inputMust be greater than 0.Alkalinity consumption factormg/L as CaCO₃ per mg/L dose · optional user-entered factor; blank or zero disables demand

Rapid Mix design mode

Choose one hydraulic basis. Volume and detention are reconciled from this mode and design flow.

Sizing from detention timeEnter detention time; volume is calculated as Q × t.Check existing basinEnter basin volume; detention time is calculated as V / Q.

Rapid-mix detention time *s · user-selected design timeMust be greater than 0.Rapid-mix velocity gradient *s⁻¹ · target GMust be greater than 0.

Jar-Test Observations

Enter each replicate separately. A dose level passes only when every replicate passes.

Dose (mg/L)	Response	Replicate ID optional	Row action

Flocculation Stages

Each stage uses design flow and one declared sizing mode.

Stage	Mode	Detention time or volume	G (s⁻¹)	Row action
		Stage 1 detention time (s)Must be greater than 0.	Must be greater than 0.
		Stage 2 detention time (s)Must be greater than 0.	Must be greater than 0.

エンジニアリングの根拠

方法

宣言された判定基準でジャーテストの反復値を分類し、入力された流量、形状、粘度、運転基準から急速混和・フロック形成の容量、滞留時間、G 値、液体動力をスクリーニングします。計算動力は液体内の散逸動力であり、モーター、軸、駆動装置または銘板の電力ではありません。

Each jar-test observation is classified independently. A dose level is confirmed PASS only when all valid replicates pass; mixed dose levels do not qualify. Replicate responses are not averaged.

Threshold interpolation is linear and bounded to adjacent unique tested dose levels. A replicated dose in a crossing bracket makes interpolation unavailable. Extrapolation is not performed.

Within-range and explicit criteria report dose-level classifications without a single interpolated dose.

Rapid-mix sizing uses V = Q × t or, for an existing basin, t = V / Q. The same physical volume is used for hydraulics and calculated liquid mixing power P = μVG². Gt = G × t.

Each flocculation stage uses either V = Q × t or t = V / Q. Calculated liquid mixing power is P = μVG² and stage Gt = G × t. The sum of stage G×t contributions is descriptive and is not asserted as a universal criterion.

Optional alkalinity demand is the user-entered factor multiplied by the lowest confirmed tested passing dose.

範囲 / 制限事項

指定されたジャーテスト基準と水質特性に基づき、実測済み用量、急速混和槽の容量と動力、各フロック形成段の滞留時間と G×t を確認します。
Does not select a coagulant, predict finished turbidity, predict pH from first principles, or guarantee full-scale performance.
A screening interpolation is not a tested dose and is never substituted for the confirmed tested dose in alkalinity demand.
No universal optimum G or Gt is asserted. Dynamic viscosity has no hidden temperature assumption.
Calculated liquid mixing power is the power dissipated in the liquid implied by entered G, viscosity, and volume. It is not motor, shaft, drive, or electrical nameplate power; equipment selection requires mechanical and drive efficiency and equipment-specific design factors.
