Fats, Oil and Grease (FOG) Treatment in ‘Grease Converters” using Bioadditives

Fats, oils and greases (FOG) have been a major problem for sanitary service providers since the advent of piped waste disposal systems. The first FOG trap was patented by Whiting in California at the end of the nineteenth century. The trap was a simple tank with a pipe inlet and outlet and has remained unchanged for over a hundred years even though the makeup of FOG has changed from being basically made up of fats that were solid at room temperature, to a multiplicity of both solid fats, and now oils that remained liquid at all temperatures.
