Floating Decanter – Efficient Wastewater Treatment with Vortex Engineering
A floating decanter is a vital innovation in modern wastewater treatment. Designed for use in Sequencing Batch Reactors (SBRs), lagoons, and clarifiers, a floating decanter allows for the efficient separation of clarified water without disturbing settled sludge. In this article, we explore how floating decanters work, their advantages, and why Vortex Engineering provides industry-leading solutions.
At Vortex Engineering, our advanced floating decanter systems are engineered to deliver durable, energy-efficient, and low-maintenance performance across a range of industrial and municipal applications.

What Is a Floating Decanter?
This type of decanter floats on the surface and adapts automatically to changing water levels. It selectively removes only the clearest layer of water, avoiding any contact with the sludge below.
Key benefits include:
Prevents sludge disturbance
Reduces clogging and upkeep
Produces high-quality effluent
How It Works
Buoyant Structure
– The system floats and adjusts with the water surface.Selective Withdrawal
– A skimmer or hose collects only the clean top layer.No Sludge Interference
– The sediment remains undisturbed at the bottom.Effluent Removal
– Clear water is discharged through a pump or gravity system.
Applications
Municipal treatment facilities (SBRs, lagoons)
Industrial sites (e.g., food processing, chemicals, paper)
Aquaculture systems and stormwater ponds
Packaged treatment units
