Abstract
Describes implementation of Air Gap Membrane Distillation (AGMD) to treat produced water.
Researchers measured the permeate fluxes, rejection factor and energy consumption for three distinct 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.
In addition, they examined the effect of feed flow rate, coolant temperature and feed temperature on permeate flux. The flux increases as the feed temperature and flow rate increase, and declines as the coolant temperatures increase. Energy consumption was measured at different pore size and was found to be independent of membrane pore size.
