FogBuster Technical Description
FogBuster reliably removes fat, oil and grease (FOG) from industrial wastewater streams with higher efficiency and lower cost than comparable systems. FogBuster can also significantly reduce BOD, COD and TSS. In wastewater with gross solids, the optional FogBuster solids extraction module removes and compacts floating and sinking debris from the effluent. The equipment works in a very broad range of temperatures and pH and can handle effluent with any oil content—including 100%, as in the case of an accidental spill.

The system is based on patented and patent-pending hydraulic technology to balance the flow of FOG and water into the ideal concentration for the integrated separation unit which then extracts the FOG from the wastewater. FogBuster technology utilizes a series of baffles (floating and fixed) and specific displacement to achieve the balance and extraction required. These baffles track the interface between FOG and effluent thereby creating a ‘wall’ of FOG. All incoming effluent is directed through this ‘wall’ which acts as a filter for further suspended FOG. (Suspended FOG is effectively pulled from the effluent by other FOG.) As a result of the FOG removal there are reductions in BOD, COD and TSS in part because a proportion of these contaminants ‘stick’ to the FOG.

The effluent enters the FogBuster primary stage (Balancing Tank) where, if necessary, the gross solids are removed using optional twin, patent-pending compressive augers. This reduces the solids volume by up to 90% and compacts the solids for economical disposal. The primary tank is heated to maintain the liquidity of all FOG content. Next, the balanced effluent is delivered to the second stage (Separation Tank). The separator hydraulically removes the FOG from the waste effluent by means of ‘pressurized flotation technology’. This process will typically remove FOG to below 100 ppm and often to the level of 50 ppm or less. Further processing (e.g., filtration) can be utilized in those particular circumstances where even higher standards are necessary. The extracted FOG is highly pure with low moisture content. It is decanted into an integral reservoir located on the side of the separator tank. This reservoir is emptied when a level sensor activates the integrated oil pump to transfer oil from the reservoir to a holding tank.
