Long-term filtration performance of nonwoven geotextile-sludge systems
A study of the filtration behaviour of contaminated wastewater treatment sludges was conducted. The laboratory portion of the study included a series of filtration tests with different nonwoven geotextiles. Filtration performance of the sludge–nonwoven-geotextile systems was also observed in field test cells by exhuming geotextile samples from the cells after exposure followed by analysis. The ...
متن کاملResistance of a nonwoven geotextile against mechanical damage and abrasion
The installation procedures (which induce mechanical damage) and abrasion can cause unwanted changes on the properties of the geotextiles. In this work, a nonwoven polypropylene geotextile was subjected to three degradation tests: (1) mechanical damage, (2) abrasion and (3) mechanical damage followed by abrasion (successive exposure). The damage caused by the degradation tests was evaluated by ...
