ABSTRACT:
A containment assembly for collecting grease or other effluent that includes a layered composite of effluent filtering and trapping materials in the form of a separation filter, a center filter and a barrier layer disposed in a layered manner. The separation filter and center filter desirably include a polypropylene material and each have a different porosity. The separation filter, center filter and barrier layer may be disposed between a top and bottom spacer layer in a layered manner. The composite may be received within a frame assembly. The effluent containment assembly also may include flashing for deflecting the effluent away from the equipment or other effluent source, an assembly for securing the frame assembly to equipment or other source of effluent at an elevation relative to a roof or other surface to be protected, a pole assembly for holding the composite within the frame assembly, and a windbar assembly for holding the composite together during wind conditions.
