Abstract:
A containment assembly for collecting effluent comprising a layered composite of materials, the layered composite including:(a) a separation filter layer for absorbing the effluent and for repelling at least some of any water present with the effluent, the separation filter layer comprising a material having a porosity sufficient to permit passage of effluent therethrough;(b) a center filter layer disposed below the separation filter layer for absorbing the effluent absorbed by the separation filter layer and for repelling at least some of any water included with the effluent passing through the separation filter, the center filter layer comprising a material having a porosity less than the porosity of the material of the separation filter layer and an effluent absorbency rate greater than the effluent absorbency rate of the material of the separation filter layer; and(c) a barrier layer disposed below the center filter layer, the barrier layer for substantially preventing the passage of any effluent from the center filter layer beyond the barrier layer.
