Aqueous Film Forming Foam (AFFF)

Aqueous film-forming foam (AFFF) solution is used extensively in fire suppression systems for aviation facilities and fire training facilities. AFFF systems are proven and essential to protect these valuable, mission essential aircraft and hangar facilities. The AFFF unit is a product designed to hold and ease application of AFFF solution. Due to its capabilities in fire suppression, the use of this tank is useful for fire protection projects.

AFFF is not considered hazardous to humans and is technically considered biodegradable and practically nontoxic. The major concern is the large volume of solution that can be produced from hangar fire protection systems. Because AFFF is biodegradable, the breakdown of AFFF by bacteria consumes oxygen. Uncontrolled AFFF discharged to the environment could deprive aquatic life of oxygen and cause fish kills. If allowed to enter the sewage treatment facilities in  relatively large volumes, AFFF foam can disrupt the treatment process by killing necessary bacterial cultures within wastewater treatment facilities (WWTFs). Many WWTF’s prohibit the discharge of AFFF laden wastewater unless the AFFF concentration is less than 50 ppm. The AFFF wastewater holding tank can be used to store foam supply or drainage after discharge.
