Removal of heavy metal ions from its low concentrated lake water via LiBr/PES hollow fiber membrane module system

The treatment of river or lake water for heavy metal removal is of special concern due to their persistence and recalcitrance in the environment. In the current study, an ultrafiltration (UF) system consisting of polyethersulfone (PES) UF hollow fiber (HF) membranes spun from Liberia doped solutions...
