Patent IL-164540-A0 (IL)
Title: Diffuser/emulsifier
IPC: B01F7/02
Filed: 2004-10-12
Abstract: A diffuser (10) provides the ability to diffuse one or more infusion materials into a host material. A rotor (12) and stator (30) rotate relative to one another. The infusion materials are drawn through openings (22) in the rotor and stator. These openings (22) are also causing turbulence within the host material, which is flowing through an area between the rotor (12) and stator (30). As aligned openings (22) pass one another, succession occurs, which provides energy to diffuse the infusion materials into the host material to an extremely high degree. The opening patterns in the rotor and stator can be designed to operate at a single frequency or at multiple frequencies. The frequencies of operation may affect bonding between the infusion materials and the host material and may also be effective in break down of complex molecular structures.

Title: Nouvelle membrane céramique de microfiltration à faible coût à base de la magnésite naturelle pour le traitement des eaux usées
Inventor: ALAMI YOUNSSI SAAD
IPC: C02F1/44
Filed: 2018-02-18
Abstract: Cette invention porte principalement sur la préparation d’une nouvelle membrane céramique de microfiltration à faible coût, à base de la magnésite naturelle. Tout d’abord, la magnésite marocaine locale a été profondément caractérisée pour comprendre ses comportements chimiques, minéralogiques et thermiques et a montré que la magnésite naturelle utilisée présente un degré de pureté élevé en termes de minéral de magnésite. Ensuite, une membrane de magnésite plate a été préparée via des méthodes de pressage uniaxial et du frittage. L'influence du frittage sur les propriétés essentielles de la membrane, notamment la morphologie, la porosité, la taille des pores, la perméabilité et la résistance mécanique, a été étudiée dans la plage de 900 à 1200 °c. Dans cette plage la porosité diminue de 51,0 % à 48,15%, une taille de pores de 1,12 µm, la perméabilité à l'eau diminue de 4209 à 2107 l/h.M2.Bar et la résistance mécanique augmente de 1.7 à 8.5mpa. Il est important de noter que l’expérience de microfiltration de la membrane de magnésite sur les eaux usées de textiles industriels a montré qu’elle clarifiait efficacement les eaux usées et que la turbidité et l’élimination de la demande chimique en oxygène pourraient atteindre respectivement 99,9% et 69,7%. Enfin, l'utilisation de magnésite naturelle moins chère pourrait permettre la production industrielle de membranes céramiques à faible coût, ce qui pourrait élargir les applications de microfiltration industrielle en tant que processus écologique.
