What Makes Grease a Problem in Collection Systems?
Grease is a major challenge to wastewater professionals across the country. Grease can significantly reduce the capacity of sewer lines and is a major cause of SSO’s. The severity of the problem is due primarily to the characteristics of grease:

• It remains liquified at 56° F.
• It solidifies at 55° F.
• It is adhesive in nature which enables it to easily attach to sewer lines.
• Grease is lighter than water (thus it floats on water).

Bacteria Versus Chemicals

Both chemical and bacteria products are widely used for controlling grease in collection systems. Chemical products, which include lift station degreasers, liquid degreasers and high pH powders (Lye) are typically used to emulsify the grease and move it downstream to destinations unknown. These products can be effective, but can be hazardous to the environment and the people using them. Bacteria is typically used as maintenance product that can be manually added or metered into a system to build up a biofilm and digest grease. In contrast to chemical products, bacteria do not emulsify the grease and send it downstream where it can become a problem again. Instead, grease is consumed and the biproduct of grease digestion is carbon dioxide and water.
