Fats, Oils and Grease (FOG):  A Solution
VaporX Information
Material Safety Data Sheet
Case Study at a Virginia Lift Station


Fats, oils and grease can clog wastewater collection and treatment systems, causing sewage spills, manhole overflows and/or sewage backups in homes and businesses.

 

Grease is singled out for special attention because of its poor solubility in water and its tendency to separate from the liquid solution. Large amounts of oil and grease in the wastewater causes trouble in the collection system pipes. It can, and often does, decrease pipe capacity and, therefore, requires that piping systems be cleaned more often and/or some piping to be replaced sooner than expected. Oil and grease also hamper effective treatment at the wastewater treatment plant.  This situation can result in a shutdown of wastewater treatment units.

 

A number of companies offer products that claim to resolve grease issues.  However, it is generally understood within the professional wastewater community that solutions are hard to come by in the absence of removal of the problem using an agressive program to stop FOG at its source (i.e. typically restaurants).

VaporX is a combination of several ingredients including an emulsifying agent and additional chemistry that contemplates providing natural bacteria with the nutrients they would need to digest the FOG once emulsified.

 

The pictures on the left represent the visual nature of the results of VaporX treatments.  The untreated photo was taken two weeks after the wet well was cleaned with a vacuum truck (Figure 1).  Two weeks of FOG buildup is obvious in this picture.  The second picture is a visual of the same wet well a few days after treatment with VaporX was initiated (Figure 2).  This picture is representative of the consistent visual quality of the FOG situation within the wet well over the three months since the initiation of treatment.

VaporX
treatment for FOG at the Wet Well was effective and represented a lower cost alternative to mechanical removal of FOG.

The addition of VaporX to a biological waste treatment system did not appear to adversely affect the biological population.

There was no sign of reformation of FOG downline from the treatment application at the Wet Well or within beakers during lab testing. 

Lab treatability results indicated that biological destruction of FOG occurred in the presence of VaporX emulsified fats, oils and grease with greater than 98% destruction after 6 hours of contact with aerated activated sludge.
