Abstract

In this study, crossflow ultrafiltration (CF/UF) was applied to ensure continuous removal of Hg-contacted FeS solids from suspension. The key parameters that are used to evaluate overall performance of the CF/UF treatment system are water flux (permeability or rejection), and variation of water qual...
