b'GENERAL INFORMATION Aqueous film-forming foam (AFFF) solution is used Aqueous film-forming foam (AFFF) solution is used extensively in fire suppressionextensively in fire suppression systems for aviation facilities and fire training facilities. AFFF systems are provensystems for aviation facilities and and essential to protect these valuable, mission essential aircraft and hangarfire training facilities. facilities. AFFF systems have superior fire extinguishing capability and can effectively control flammable or combustible liquid fire resulting from aviationand shipboard accidents.FEATURESSizes Ranging FromThe ParkUSA AFFF unit is a product designed to hold and ease application 500 - 20,000 Gallonsof AFFF solution. Due to its capabilities in fire suppression, the use of this tank OSHA Manway Access Coveris useful for fire protection projects.Chemical Resistant Tank AFFF is not considered hazardous to humans and is technically consideredConstructionbiodegradable and practically nontoxic. The major concern is the large volumePrepackaged System for Easy of solution that can be produced from hangar fire protection systems. BecauseSpecification & InstallationAFFF is biodegradable, the breakdown of AFFF by bacteria consumes oxygen.Maintenance Notification Uncontrolled AFFF discharged to the environment could deprive aquatic life System; Alerts of Tank Full of oxygen and cause fish kills.

Many WWTFs prohibit the discharge of AFFF laden wastewater unless the AFFF concentration is less than 50 ppm. MODELSThere are currently two models available for the ParkUSA AFFF unit,these configurations are given by the material of construction:The ParkUSA AFFF-C Series is manufactured of Class II 4500 PSI precast concrete. Pre-casting the concrete shell insures that all units achieve structural and physical uniformity. The units are structurally engineered for H-20 truck loading and can be buried without any need for any other structural protection. The unit is of monolithic construction at bottom and walls to insure against joint leakage.The ParkUSA AFF-S Series is of -inch thick ASTM A36 carbon steel. All weldingis performed in accordance to American Welding Society D1.1 standards.The inlet, outlet, vent, and drain connections shall be standard duty Class 150 PSI. Interceptor shall have lifting lugs, gasketed access covers, site glass, makeup water valve port, and support beams. The unit shall be coated inside and outside witha fire retardant and corrosion resistant coating system. The coalescing mediapack is of modular construction for easy maintenance and constructed of noncorrosive materials.The ParkUSA AFFF-F Series is manufactured fiberglass or plastic and is used where lightweight construction is required.AFFF Wastewater Holding Tank412'
