Clarifier Design — AguaClara 0.0.0 documentation - GitHub Pages
The AguaClara clarifier is a high-rate vertical flow clarifier that is designed with the following goals: Minimize secondary currents that could send high velocity flow through some of the plate settlers
Primary settling is the settling of a dilute suspension of mostly flocculent particles (raw wastewater TSS). There is no distinct interface between the settling sludge and clarified supernatant. TSS removal typically is 50% to 65%. Most TSS settle faster than activated sludge, and sludge compacts better.
NEWEA | Optimizing Clarifier Performance—Are We Designing the Clarifiers Right? | • Relatively small inlet pipe and slots – potential floc shear • Mixed liquor fed at top of tank – potential waterfall effect • Impinging exits and submerged flocwell are steps in the right direction From WEF (2005) Clarifier Design, Manual of Practice
Clarification Design Challenge — AguaClara 0.0.0 documentation
Designing a clarifier requires selecting several key design parameters. The floc filter upflow velocity sets the plan view area of the clarifier and thus directly controls the cost of the concrete tank.
Clarification Introduction — AguaClara 0.0.0 documentation
In our discussion of horizontal and vertical flow clarifiers, an important design parameter was capture velocity which was set by flow rate and plan view area of the clarifier. With the introduction of plate settlers, the important design parameter changes.

There are numerous control options that plants use to run their clarifier more efficiently. Monitor the flow through the secondary clarifier. Flow rates greater than the design overflow rate may result in an increase in the effluent solids content. This picture shows hydraulic overloading in …

Clarifier Design Parameters - Hydroflotech
Determining the hydraulic loading ratio required to meet your effluent requirements (ppm, mg/l) is an important step in the design and sizing of any clarification system. A small change in the hydraulic loading ratio can result in a large change in the size of the specified clarifier. For example look at the following spreadsheets.
