Community Fuels is one of the largest biodiesel manufacturers in the United States, producing this carbon neutral fuel from a variety of feedstocks. 

To increase their production and improve the product quality in order to meet the ASTM cold soak test they decided to conduct an extensive engineering study to determine what technology could improve their existing biodiesel filter system.

Community Fuels had been utilizing a series of bag filters sized at 1 micron, and had been manually pre-coating the bags with D.E. The biodiesel filtration bags were changed daily, and were thrown away after a single use.
