  • Composite mixed matrix membranes for membrane distillation and related methods of manufacture
    Patent number: 11141704
    Abstract: The present invention relates to a membrane distillation system comprising a flat-sheet composite mixed matrix hydrophilic/hydrophobic membrane having at least a hydrophilic layer and a hydrophobic layer. The hydrophilic layer comprises a hydrophilic polymer and inorganic nanoparticles having high thermal conductivity. The hydrophobic layer comprises fluorinated surface-modifying macromolecules (SMM). Also disclosed is a phase inversion method for manufacturing the membrane.

  • METHOD FOR TREATING AQUEOUS SALINE STREAMS
    Publication number: 20170036937
    Abstract: A method for treating aqueous saline streams, specifically saline effluents, by means of membrane distillation with pre-treatments, in order to remove total calcium hardness and permanent calcium hardness and the presence of sulphates in saline effluents, more specifically in residual brines from desalination plants. The system makes it possible to concentrate brines above 37% by weight, i.e. above the saturation level, which makes it possible to reduce the volume of brine considerably, making it suitable for other industrial uses and producing pure water.
