Rapid on-site analysis of fats, oil and grease (FOG)
It is estimated that 23-28% of Sanitary Sewer Overflows (SSOs) are due to Fats, Oils and Grease (FOG) or as much as 19 million gallons from 1998 to 2001 (State of North Carolina, 2004). Our increasingly mobile society has led to a decrease of cooking at home and a significant growth in the commercial food sector. This, on top of other industries such as metal processors, meat packers, cosmetic ...
