description The prevalence drawback of membrane technology applications is rapid flux declines due to fouling. Membrane fouling analysis is vital to explicitly understand fouling occurrences.

The thermogravimetric analysis (TGA) has been employed to quantify foulant as an approach to evaluate the performance of AgNPs for fouling mitigation during surface water filtration. In this study, two types of AgNPs, namely AgNPs-1 and AgNPs-2, were respectively incorporated in the PVDF ultrafiltration (UF) membrane.
