Foam Fractionators
|
Design & Function
AAT Foam Fractionators, often referred to as protein skimmers, work by injecting air (or an air/ozone mix) into a contact chamber containing system water. This process results in organic molecules collecting on the surface of the air bubble by the process of absorption. These bubbles rise in the contact chamber collecting at the surface forming a froth or proteinaceous scum. The foam fractionator process removes dissolved organic carbon down to sizes which cannot be mechanically filtered. Use of ozone promotes microflocculation and electrostatic attraction, improving the removal efficiency of organic wastes. |

The end result is removal of nitrogenous wastes, non bio-degradable dissolved organic carbon and a reduction in turbidity, along with achieving O2 saturation in the returning process water.
Construction
The units are assembled from 5 sub-components and are able to be disassembled for cleaning or maintenance. All wetted parts are of PVC or vinyl ester reinforced fibreglass. Securing bolts are stainless steel.
Configuration
Units can be modified or custom manufactured to suit special requirements.
All units are robustly moulded from 1200 and 3000gm high quality fibre reinforced material. External surfaces are gel coated for UV stability, ease of maintenance and a smooth finish.
All AAT Foam Fractionators are designed and manufactured to the highest standards of quality and performance.
