Method & Evidence

AimTo investigate the impact of nanotechnology formulations and structural modeling on the hydraulic permeability and filtration performance of nonwoven geotextiles.

MethodExperimental and modeling approach

ProcedureNanoclay (yellow clay) was incorporated into polyester formulations to create nonwoven geotextiles. The engineering behavior, specifically the removal of toxic and organic components from leachate, was evaluated. Additionally, sustainable laminar geotextile composites with varying fiber-packing densities were fabricated and tested for water permeability using a permittivity test. A structural model of tubes was applied to interpret water permeability behaviors, and the influence of pore inlet forms (bell mouth and soft tube structures) on hydraulic pressure loss was estimated.
