Abstract

Cette invention concerne le domaine du traitement du concentrât (saumures) sur les bases d'un traitement générique par osmose inverse. Elle intervient dans le secteur du traitement d'eau permettant d'accroître la reconversion des rejets sur un traitement de ressource primaire. Les techniques antérieures permettent simplement de traiter l'eau de mer de façon conventionnelle n'apportant aucune solution adéquate sur la sursaturation, aucune solution sur l'économie d'énergie (méthode énergivore), aucune solution sur la préfiltration et un taux de reconversion faible.L'OTC permet d'accroître la production de ressource traitée, d'économiser de l'énergie et de préserver les membranes d'osmose inverse.This invention relates to the field of treatment of concentrate (brines) on the basis of a generic reverse osmosis treatment. It is involved in the water treatment sector, making it possible to increase the conversion of waste to primary resource treatment. The prior techniques simply allow seawater to be treated in a conventional manner providing no adequate solution on supersaturation, no solution on energy saving (energy-consuming method), no solution on pre-filtration and a low conversion rate. The OTC makes it possible to increase the production of treated resource, to save energy and to preserve the membranes of reverse osmosis.
