01 · USER INPUT

Design basis and inputs

Rapid Mix design mode

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

Jar-Test criterion

Jar-Test Observations

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

Flocculation Stages

Each stage uses design flow and one declared sizing mode.

Ingenieurtechnische Grundlage

Methodik

Ordnet Jar-Test-Wiederholungen dem erklärten Kriterium zu und prüft Volumen, Aufenthaltszeit, G und Flüssigkeitsmischleistung von Schnellmischung und Flockung anhand eingegebener Durchfluss-, Geometrie-, Viskositäts- und Betriebskriterien. Die berechnete Leistung wird in der Flüssigkeit dissipiert und ist keine Motor-, Wellen-, Antriebs- oder elektrische Nennleistung.

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.

Umfang / Grenzen

  • Verwenden Sie die angegebenen Jar-Test-Kriterien und Wassereigenschaften, um bestätigte Testdosierungen, Schnellmischvolumen und -leistung sowie Aufenthaltszeit und G×t jeder Flockungsstufe zu prüfen.
  • 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.
