INVESTIGATION OF FILTRATION CHARACTERISTICS OF A NONWOVEN FABRIC FILTER

The purpose of this study was to investigate the behavior of a nonwoven fabric filter in subdrainage applications. Experiments were restricted to a single fabric, Mirafi 140. Conventional aggregate filters were tested under compatible conditions to provide a basis of performance behavior. Experimental results indicate that the nonwoven fabric provides desirable performance under a relatively wide range of soil conditions. Hypotheses that relate to mechanisms controlling the behavior of the nonwoven fabric in subdrain applications are discussed. These mechanisms are, in turn, related to induced filtration and internal grading of the soil near the soil-fabric contact surface.
