Effective FOG Control: Managing Fats, Oils, and Grease in Wastewater Systems

Fats, oils, and grease (FOG) are common byproducts in both residential and industrial settings. When improperly disposed of, they can accumulate in sewer systems, leading to blockages, sanitary sewer overflows (SSOs), and environmental hazards. Effective FOG control is essential for municipalities and industrial clients to maintain efficient wastewater infrastructure and protect public health.

Understanding FOG: What Are Fats, Oils, and Grease?

FOG refers to the fatty substances derived from animal and plant sources used in cooking and food preparation. Common sources include:

  • Animal Fats: Lard, butter, and meat drippings.

  • Vegetable Oils: Olive oil, canola oil, and margarine.

  • Dairy Products: Milk, cream, and cheese residues.

These substances are liquid when hot but solidify upon cooling. When washed down drains, they can adhere to pipe walls, leading to significant blockages over time.

The Science Behind FOG Accumulation

In wastewater systems, FOG undergoes physical and chemical changes:

  1. Cooling and Solidification: As FOG cools, it solidifies and attaches to sewer pipe walls.

  2. Saponification: FOG can react with calcium and magnesium in wastewater to form soap-like compounds, further contributing to blockages.

  3. Biofilm Formation: Microorganisms can colonize FOG deposits, creating biofilms that exacerbate blockages and produce foul odors.

Understanding these processes is crucial for developing effective FOG control strategies.


Consequences of Inadequate FOG Control

Without proper FOG control measures, municipalities and industries may face:

  • Sewer Blockages: Accumulated FOG restricts wastewater flow, leading to backups.

  • Sanitary Sewer Overflows (SSOs): Blockages can cause untreated sewage to overflow into the environment, posing health risks.

  • Increased Maintenance Costs: Addressing FOG-related issues requires significant resources for cleaning and repairs.

  • Environmental Pollution: SSOs can contaminate local waterways, harming aquatic ecosystems.

Traditional FOG Control Measures

Common approaches to FOG control include:

  • Grease Traps and Interceptors: Devices installed in plumbing systems to capture FOG before it enters the sewer lines.

  • Public Education Campaigns: Informing the public about proper disposal methods to prevent FOG from entering the wastewater system.

  • Regular Maintenance: Scheduled cleaning of sewer lines and grease traps to remove accumulated FOG.


While these methods can mitigate FOG issues, they often require significant labor and resources and may not address the root cause of FOG accumulation.


In-Pipe Technology’s Innovative Approach to FOG Control

In-Pipe Technology offers a proactive solution to FOG control by introducing specialized, non-pathogenic bacteria into the sewer system. These bacteria metabolize FOG, breaking it down naturally and preventing accumulation.
