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 hydrophobie layer on the hydrophilic layer, and allowing the layers to forma 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 hydrophobie 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.
