Application of polyelectrolytes for improving the dewatering performance of drinking water treatment sludge using geotextiles

Revista Ambiente & Água, 2021
The sludge generated at drinking water treatment plants (WTPs) is a high-moisture content residue, and therefore difficult to handle, transport, dispose of or recover. During the last decades, geotextile tubes have been successfully applied to reduce the
