Abstract
Authors evaluated microfiltration (MF),
ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) membranes
for their ability to achieve the world's most stringent Hg discharge criterion
in an oil refinery's wastewater.
The membrane processes were operated at three
different pressures to demonstrate the potential for each membrane technology
to achieve the targeted effluent mercury concentrations. The presence of
mercury in the particulate form in the refinery wastewater makes the use of MF
and UF membrane technologies more attractive in achieving very low mercury
levels in the treated wastewater.
