A mathematical model was developed to lead to the design of a novel membrane, which can operate in membrane distillation at a small trans-membrane temperature gradient, including at low feed water temperature range. The novel membrane design can be described as a super-hydrophobic nano-porous/micro-porous composite membrane. This membrane will significantly decrease the energy requirements of the MD process since it can operate at very low inlet feed temperatures.

Super-hydrophobic nano-porous/micro-porous composite membranes for membrane distillation operating at low inlet feed temperatures with low energy consumption

Provided is a method of manufacturing a multilayer mixed matrix membrane which includes providing a support layer, casting a hydrophilic layer on a surface of the support layer, casting a hydrophobic layer on the hydrophilic layer, and allowing the layers to form a multilayer mixed matrix membrane. Also provided is a method of manufacturing a hollow fiber composite matrix membrane which includes providing a first solution having a hydrophilic polymer, providing a second solution having a hydrophobic polymer, and extruding the first and second solutions to form a multilayer hollow fiber composite matrix membrane. Additionally, a plate-and-frame membrane module for direct contact membrane distillation using a multilayer mixed matrix membrane is provided. The plate-and-frame membrane module includes a feed inlet capable of distributing process solution throughout the membrane module, a permeate inlet capable of distributing process solution throughout the membrane module, a tortuous promoter comprising multiple flow channels, a feed outlet, and a permeate outlet.
