General product information

The FOAM BREAKER consists of a Submersible Motor which drives an Archimedes’ type Impeller, SCREWPELLER®, that is partially located in a vertical Volute, cylindrical or conical shaped. A Gas Exhaust Tube is required, located in the Volute, above the Impeller. The SCREWPELLER® aspirates the water from the Volute, and creates a water flow in the basin that moves the foam layer towards the upper side of the Volute. The foam is sucked into the Volute and, by the action of the SCREWPELLER®, the air is released from the foam and evacuated through the Internal Tube.

The FRED is designed to re-entrain fat and a thick floating sludge layer, but no light sludge. A sludge or foam layer that partially or completely covers the motor housing can be harmful for the motor! The backflow impeller will constantly fill the volume above the downdraft impeller, to limit the aspiration of air. The surface water, including the fat and sludge layer will be sucked into the downdraft SCREWPELLER®, which will create a powerful flow downwards. Next, this flow will bend against the bottom of the basin and will be radially directed in all directions towards the basin side and back up to the surface. Thanks to this optimal flow, the basin volume will be mixed.

The FRMD/MIX-SL combines 2 units in one: the FRMD, which is a Floatables Removal Device, and the MIX-SL, which is a Submersible downdraft Mixer, mounted vertically underneath the FRMD.

FB

Foam Breaker


{aqt}fblarge fb2large{/aqt}

FB Foam Breaker

To assist bio-digestion FB aspirates and breaks high volumes of foam forming on the surface of some biological and thermophilic reactors. Foam is sucked into the volute where the degassing phase allows air to vent to atmosphere and liquid to re-entrain. Nothing is discharged from the basin.

Applications
High FOG treating biological reactors
High foaming influent
Thermophilic reactors
Biological treatment of animal waste

Range
1.5 - 15kW, EMOD motor - IP 68
4, 6 + 8-Pole Speeds, direct drive
2 + 3 float options
AISI 304/316 or special SS

Features
Blockage free + high flow volute
Unique air/liquid separation + discharge
Reliable + non-clogging impeller
Simple installation + removal

Configurations
Fixed + pontoon mount options
Vertical operation only
1 x Submerged drive
Fixed or variable WL options

FRED

Floatables re-entrainment device


{aqt}fredlarge fred2large{/aqt}

FRED Floatables Re-entrainment Device

 
Radial mixing draws surface FOG towards the centric downdraft flow of the dual-action impeller where the homogenization phase allows re-entrainment with the biological process. FRED prevents settlement and crust formation as well as mixing the entire basin. Nothing is discharged from the basin.
 
Applications
High FOG + scum conditions
Viscous + sludge bulking problems
Grease trap upstream of biological reactor
SBR
 
Range
1.1 - 22kW
4-Pole Speed, direct drive
3 Floats
AISI 304/316 or special SS
 
Features
Special dual-action impeller
Excellent mixing performance
Reliable + non-clogging design
Simple installation + removal
 
Configurations
Pontoon mount only
Vertical operation only
1 x Surface drive
Fixed or variable WL.

FRMD MIX-SL

Floatables Removal Device
Submerged Mixer

{aqt}frmdmixsllarge frmdmixsl2large{/aqt}

FRMD MIX-SL Floatables Removal Device + Submerged Mixer

Radial mixing in conjunction with surface flow generated by the submersible pump draws FOG towards the basin centre. A special adjustable scum weir allows a laminar layer of FOG to enter the pump intake for discharge from the basin. Non-contaminating so ideal for disposal and reuse applications.

Applications
Removal of bulking + old sludge
Removal + reuse of FOG
Sludge stabilisation + biogas
SBR

Range
1.5 - 22kW, EMOD motor - IP 68
4 + 6-Pole Speeds, direct drive
Multiple pump flow rate options
AISI 304/316 or other SS

Features
Adjustable flow rate
Purpose designed blockage free pump
Reliable + non-clogging impeller
Simple installation + removal

Configurations
Pontoon mount only
Vertical operation only
1 x Submerged drive + pump
Fixed or variable WL.
