MIX FILL	REACT FILL	REACT


SETTLE	DECANT/SLUDGE WASTE

MIX FILL -

Influent enters reactor
Complete mix of contents is achieved without use of aeration
Controls filamentous organisms
Essential for systems requiring phosphorus removal

REACT FILL -

Influent flow continues under mixed and aerated conditions
Aeration may be intermittent to promote aerobic or anoxic conditions
Nitrification and denitrification is easily managed
Aeration source may also be turned down during low flow conditions
to conserve energy

REACT -

Influent flow is terminated
Mixing and aeration continue in absence of raw waste
Dissolved oxygen probes can be used to deliver oxygen on "as needed" basis without loss of mixing
Provides a treatment barrier that separates the Fill phases from the Settle and Decant Non-Fill phases

SETTLE -

Influent flow does not enter reactor
Mixing and aeration cease
Ideal solids/liquid separation is achieved due to perfectly quiescent conditions
Adjustable time value allows settling time to match prevailing process needs

DECANT/SLUDGE WASTE -

Influent flow does not enter reactor
Mixing and aeration remain off
Decantable volume removed by subsurface withdrawal
Reactor is immediately ready to receive next batch of raw influent
A small amount of sludge is wasted near end of each cycle

AquaEnsure® Ballast Decanter

The performance engineered decanter is an integral component of the AquaExcel® system. It is a floating unit designed for subsurface withdrawal of effluent from the reactor only during the Decant Phase of operation. The design allows air supply flexibility and low entrance velocity. The decanter is also maintenance-free with no in-basin servicing required.

Aqua Electric Actuated Decanter

The Aqua Electric Actuated Decanter is a floating unit which responds to the varying water levels. This decanter employs a submerged circular weir which opens only during the decant phase, following settling, and draws supernatant from below the water surface. This design also prevents mixed liquor, floating scum and debris from entering the decant line, and ensures that only high quality effluent is discharged.
