Membrane Distillation (MD) is a thermally-driven separation
process, in which only vapour molecules transfer through a microporous
hydrophobic membrane. The driving force in the MD process is the vapour
pressure difference induced by the temperature difference across the
hydrophobic membrane. This process has various applications, such as
desalination, wastewater treatment and in the food industry.
This review addresses membrane characteristics,
membrane-related heat and mass transfer concepts, fouling and the effects of
operating condition. State of the art research results in these different
areas will be presented and discussed.

Air Gap Membrane Distillation, using a high
concentration of NaCl, MgCl2, Na2CO3, and Na2SO4, is implemented in this
study. Permeate fluxes are measured for different feed concentrations and
membrane pore sizes (0.2 and 0.45 μm). The flux declines as the concentration
of salt increases, and increases as the pore size increases. The TF200
membrane showed excellent hydrophobicity compared to TF450. Moreover, the
energy consumption was measured at different salt concentrations for the
different membrane sizes, and was found to be independent of membrane pore
size, salt type and salt concentration in the feed solution.

Air Gap Membrane Distillation (AGMD) has been
implemented for four different salts. The permeate fluxes of sodium chloride
(NaCl), magnesium chloride (MgCl2), sodium carbonate (Na2CO3),
and sodium sulphate (Na2SO4) are measured at different
feed concentrations and different operating parameters using
Polytetrafluoroethylene (TF200) membrane. The influence of membrane pore size
is investigated for the different salts. Also, the effect of feed
concentration, feed temperature, coolant temperature and feed flow rate on
permeate flux is studied. The flux declines as the concentration of salt and
coolant temperatures increase, and increases as the feed temperature and flow
rate increase. Moreover, the energy consumption was measured at different
salt concentrations for the different membrane pore size and was found to be
independent of membrane pore size, and salt type.

Air Gap Membrane Distillation
(AGMD) has been implemented to treat produced water. The permeate fluxes,
rejection factor and energy consumption for three different membranes, TF200,
TF450 and TF1000, with pore sizes of 0.2, 0.45 and 1 μm, respectively, are
measured at different operating parameters. The influence of membrane pore
size is investigated for the produced water. Also, the effect of feed flow
rate, coolant temperature and feed temperature on permeate flux is studied.
The flux increases as the feed temperature and flow rate increase, and
declines as the coolant temperatures increase. Moreover, the energy
consumption was measured at different pore size and was found to be
independent of membrane pore size.

In this poster, air gap membrane distillation (AGMD) has been
implemented to treat produced water.
The experimental set-up was specially designed for this work. PTFE
membranes with different pore sizes 0.2, 0.45 and 1 µm have been used. The
permeate flux and energy consumption were measured in horizontal position of
the membrane module. The poster also
presents the ability of AGMD to treat produced water. Also, it demonstrates
the recent findings on the influence of different operating parameters such
as the feed temperature, feed flow rate and coolant temperature on the
permeate flux. Moreover, the salt and organic rejection factors and energy
consumption is shown.
