About US

The Fogbusters™ System is a revolutionary technology for removing fat, oil and grease (FOG) from wastewater.

This elegantly simple, patented technology works in conjunction with your current DAF, centrifuge, biological or other treatment systems to recover the FOG from your wastewater with little to no chemicals. The FogBuster™ can be installed (1) at the head of your oily wastewater before it reaches your DAF, (2) in your process rooms where you can capture FOG in its purest form (3) in place of your current DAF or other system. Whatever the situation, the FogBuster will fit into your existing process to minimize downstream load and maximize recoverable oil

Dissolved Air Flotation (DAF) is a traditional technology for FOG removal.

DAF requires costly chemicals and produces an oily mixed-waste sludge that must often be disposed of in landfills at significant cost. Moreover, DAF works only in a narrow pH range, is effective only on wastewater with low FOG concentrations a fails at higher oil concentrations a is labor intensive.

The Technology


The FogBuster reliably removes fat, oil and grease (FOG) from industrial wastewater streams with higher efficiency and lower cost than other systems. The Fogbuster can also significantly reduce COD, BOD and TSS. In wastewater with gross solids, the optional Fogbuster L’Vala solids extraction module removes and compacts floating and sinking debris from the effluent. The technology works in a 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 FogBusters System is based on patented and patent-pending hydraulic technology. The Fogbuster can have up to three stages depending on wastewater volume and complexity.

Effluent first enters the Fogbuster via its primary stage (Balancing Tank) where, if necessary, the gross solids are first removed using the optional L’Vala compressive . The auger compression dewaters the solids and reduces their volume by up to 90% for economic disposal. In the Balancing Tank the Fogbuster also “balances” the flow of FOG and water into the ideal concentration for the secondary stage, the Separator, which extracts the FOG from the wastewater. If the FOG in the incoming effluent exceeds 50%, a sensor triggers the system to briefly close the effluent inflow valve and open a fresh-water valve to dilute as necessary. Once the mix is diluted to below 50% oil, the system reverts to normal. Other sensors detect excessive effluent levels within the unit, flow rate and outlet effluent quality.

The FogBusters  utilizes specific displacement and a series of geometrically precise baffles (floating and fixed) to achieve the balance and extraction required. These baffles track the interface between FOG and effluent thereby creating a “wall” of FOG. All effluent is directed through this “wall” which acts as a filter to further remove 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 Separation Tank then extracts the FOG from the wastewater and ejects it under gentle pressure through a series of valves at the top of the separation chamber. From there, the highly concentrated oil flows via gravity into a reservoir attached to the side of the Separator and then automatically transfers the recovered oil to a holding tank via a sensor-activated pump. The extracted FOG is highly pure with low moisture content.

Where required, a Final Recovery Tank will target any remaining FOG and re-circulate it to the start of the Fogbuster system for further processing.

The entire system is controlled and fully automated by Allen-Bradley or Siemens PLC touch screen controller interface. This interface is compatible with a variety of data communication technologies.

The ROI and financial impacts from the use of a Fogbuster are significant but it's also about sustainability.

Recovers oil in a valuable/saleable form instead of an oily sludge with costly disposal issues.

Most biofuel feedstocks (corn, canola, oil palm and other oil crops) divert cropland and other resources from food production (the food vs. fuel dilemma).
