Fat Traps & Grease Separators

Fat traps and grease separators are essential pretreatment devices for food service establishments and food processing facilities, preventing fats, oils, and grease (FOG) from entering drainage systems and wastewater treatment plants. FOG causes pipe blockages, pump failures, and treatment process disruptions, making effective separation critical for system reliability and regulatory compliance.

These gravity separation devices exploit the lower density of fats and oils compared to water. As wastewater flows through the separator at reduced velocity, FOG rises to the surface forming a floating layer while heavier solids settle to the bottom. Clarified water flows from the middle zone to the drainage system. Regular maintenance removes accumulated grease and solids, maintaining separation efficiency.

Spans Envirotech designs and supplies grease separation systems ranging from compact under-sink units for small kitchens to large outdoor interceptors for industrial food processing. Our solutions comply with local plumbing codes, incorporate features for easy maintenance, and ensure reliable FOG removal protecting both on-site drainage and municipal collection systems.
