Abstract
Researchers employed Air Gap Membrane
Distillation (AGMD) to treat produced water. They measured the permeate fluxes,
rejection factor and energy consumption for three membranes: TF200, TF450 and
TF1000, with pore sizes of 0.2, 0.45 and 1 μm, respectively, at various
operating parameters. They studied the influence of membrane pore size for the
produced water. The effect of feed flow rate, coolant temperature and feed
temperature on permeate flux was studied, as well.
Researchers observed that the flux increases as
the feed temperature and flow rate increase, and declines as the coolant
temperatures increase. Energy consumption was measured at various pore size and
was found to be independent of membrane pore size.
