Evaluation of clay added nonwovens as filter in waste landfill

Abstract

In this, study, the yellow clays were added to the nonwoven geotextiles to improve the removal effects of the toxic and organic components of the leachate solutions which are very dangerous to the men's health. 4 types of functional nonwoven geotextiles were manufactured with the different composition of yellow clays. We applied these functional nonwoven geotextiles to the waste landfill fields as a filtration material of leachate solutions and tested tensile properties before/after application. Chemical and biological resistances of these nonwoven geotextiles were also evaluated and the amounts of absorptions of toxic and organic components were compared to the simply manufactured polyester nonwoven geotextiles.
