Product Overview The Secondary Clarifier for Livestock Wastewater separates biological solids from mixed liquor after an activated sludge treatment stage. Settled biomass is withdrawn for return to the aeration process or directed to waste sludge handling, while clarified effluent passes over an outlet weir to the next treatment step. The system can be configured for commercial pig farms, livestock production sites, and agricultural wastewater treatment plants.
Key Features
  • Controlled inlet distribution supports calm settling of activated sludge flocs.
  • A project-selected scraper or suction collection mechanism removes settled sludge from the basin floor.
  • An effluent launder and weir collect clarified water; a scum removal arrangement can be included where required.
  • Return activated sludge and waste activated sludge connections integrate the clarifier with the biological treatment process.
  • Accessible drive, bridge, and service areas support inspection and routine maintenance.
Structural Components A typical circular arrangement comprises a concrete or engineered tank, central feed well, inlet baffles, rotating bridge and drive, sludge collection mechanism, sludge withdrawal pipework, peripheral effluent weir and launder, and access provisions. Scum baffles and a surface skimmer are available according to the process design. Tank construction, mechanism materials, and corrosion protection are selected for the wastewater and site conditions.
Working Principle Mixed liquor enters from the biological reactor and is distributed through the inlet zone. As flow slows, activated sludge settles to the basin floor and clarified water rises toward the outlet weir. The collection mechanism moves or withdraws settled solids to the sludge discharge system. Part of the sludge may be returned to the aeration tank as return activated sludge; excess solids are removed as waste activated sludge. The hydraulic and sludge withdrawal design must match the biological process.
Technical Specifications
  • Design flow, tank diameter, and water depth: According to project requirements.
  • Surface overflow rate and solids loading: Determined from process design and sludge settling characteristics.
  • Sludge collection method: Scraper or suction arrangement, available upon request.
  • Mechanism and wetted-part materials: Customizable according to wastewater chemistry and corrosion exposure.
  • Drive, controls, and instrumentation: Specified according to project requirements.
  • Outdoor protection: Designed according to local climate and farm conditions.
Applications Used after an activated sludge aeration stage in pig farm and other livestock wastewater treatment plants. It is suitable where the treatment train requires biological solids separation before polishing filtration, disinfection, or a site-approved discharge or reuse step. Upstream screening, manure separation, and flow equalization should be considered according to the influent conditions.
Customization Options Basin geometry, bridge arrangement, sludge withdrawal method, effluent launder, scum handling, material selection, and control interfaces can be coordinated with the farm treatment layout. Access routes and ancillary steel structure building connections can be planned around the available plot, pipe elevations, and maintenance requirements.
Installation & Maintenance Install the mechanism in a basin constructed to approved structural and dimensional drawings. Verify bridge alignment, drive rotation, scraper or suction clearances, pipe connections, and weir levels before commissioning. Routine maintenance includes inspecting the drive and bearings, cleaning launders and scum equipment, checking sludge withdrawal, and monitoring the sludge blanket and effluent clarity. Safe access should be provided for operators.
Product FAQ

Where does a secondary clarifier sit in the treatment train?
It follows a biological treatment stage, typically an activated sludge aeration tank, and separates biomass from treated water.

Can it replace a primary manure separator?
No. Coarse manure solids should be managed upstream to protect the biological process and clarifier.

How is the clarifier sized?
Sizing considers design flow, peak loading, mixed liquor concentration, sludge settleability, and the required return and waste sludge rates.
