    Abstract: There is provided a membrane module comprising a membrane package comprising at least two membrane sleeves, wherein the membrane package is configured to allow essentially free flow of a first stream inside the sleeves and essentially free flow of a second stream between each two adjacent sleeves, and a frame, configured to support the membrane package, such that part of each of four surfaces of the membrane package is affixed to predetermined areas in the frame, forming a module having separate spaces configured to facilitate separate flows of the first stream and the second stream through the membrane package. The invention further provides a multi-modular stack, comprising at least two membrane modules and at least one membrane, wherein the first stream is fully enclosed inside each module and the second stream flows through all the modules.

    Abstract: Systèmes générateurs de vapeur (20) où des composants mouillés par la vapeur et l'eau sont fabriqués à partir de matériaux résistant à la corrosion. Cela diminue le besoin de traitement chimique de l'eau d'alimentation pour retirer des solides dissous de l'eau d'alimentation. Des résines échangeuses d'ions (98) sont utilisées à cet effet afin de retirer des substances contaminantes à la fois du condensat et de l'eau d'appoint. Le traitement de l'eau d'alimentation est complété par le filtrage de solides en suspension du condensat et de l'eau d'appoint et par l'utilisation de la désaération de la citerne (64) dans la mesure ou cela est nécessaire pour abaisser la teneur de l'eau d'alimentation en gaz dissous à un niveau acceptable.

    Abstract: A method for removing and recovering ammonium and/or potassium and/or phosphate ions from wastewater is presented which comprises:

    - permitting said wastewater. to pass through at least one bed of ion-exchange resins capable of removing selectively those nutrient ions
    - regenerating those ion-exchange resins with a Na Cl solution or other suitable regenerant solutions so that said nutrient ions may be obtained in a much more concentrated form
    - adding to said regeneration eluates (or, eventually, directly to wastewater) at least one Mg salt, in proper pH conditions so as to precipitate hydrous MgNH 4 P0 4 and/or MgKP0 4 , slightly soluble salts of great agronomic value.
