Abstract

Séparateur à membrane dans lequel une substance est séparée en utilisant une membrane semi-perméable pour obtenir soit une solution diluée, soit une solution concentrée, soit les deux. Le fonctionnement le plus économique du séparateur à membrane permet d'obtenir une quantité maximale d'un liquide désiré avec une énergie minimum, c'est à dire en réduisant au minimum la quantité d'énergie requise par unité de solution obtenue. Jusqu'ici, une puissance minimum était obtenue à la pression maximum correspondant aux performances de la membrane semi-perméable; par conséquent, la quantité d'énergie requise n'était pas le minimum. Le séparateur à membrane ci-décrit comprend un contrôleur de débit pourvu d'un circuit de commande qui calcule la puissance minimum nécessaire au débit d'une solution diluée ou concentrée, en fonction de la courbe de performance de la pompe, de la courbe de performance de l'organe de récupération de puissance et de la relation entre la concentration et la pression osmotique d'un soluté dans la solution, en tenant également compte de la courbe de performance de l'organe de récupération de puissance. Un mode de réalisation de l'invention comporte un organe de détection du débit d'un liquide circulant jusqu'au séparateur à membrane ou d'une solution concentrée ou diluée provenant de cette membrane, et un circuit de commande permettant de réguler une soupape de régulation de pression ou un organe de récupération de puissance de manière à faire coïncider la valeur du signal provenant de l'organe détecteur de débit avec le débit théorique dans le système. Dans une variante, l'organe détecteur de débit est pourvu d'un circuit de commande, faisant office d'organe détecteur de pression, qui commande la soupape de régulation de pression ou l'organe de récupération de puissance de manière à faire coïncider la valeur indiquée par l'organe détecteur de pression avec la pression correspondant à la pression théorique dans le système. L'organe détecteur de débit ou de pression est disposé entre une pompe et une membrane semi-perméable ou dans la partie d'une conduite de solution concentrée se trouvant en aval de la membrane semi-perméable.
