Current use of ion exchange unit process in water treatment for food industry is mainly for boiler feed water softening. However, potentials of ion exchange in water treatment process are of greater significance, which is exactly the matter researched in this paper. After a short review of ion exchange unit process basics, and ion exchangers as an equipment (in scope of that, a suggestions for investitor about techno-econommic analysis of offered solutions for ion exchanger line design is given, in order to minimize errors in plan and design, which might be harmful for investitor), options of using ion exchange in some phases of water treatment process for food industry are discussed, like removing of: mineral matter (softening, decarbonization, demineralization), natural organic matter, and some other constituents (nitrate, ammonia, heavy metals).

The invention refers to the methods of obtaining food (i.e. drinking, table and mineral) water. It includes extraction of the natural water from a source, its filtration and continuous disinfection through the electrolysis of argentum. Prior to the disinfection water is divided into portions through filling up reactors. The water processed is periodically poured into a collector. A mathematical equation is developed for choosing the number of reactors. The method may be used in municipal management and agriculture for improvement of water and in Pharmaceutical industry and medicine for production of drugs and solutions

Les possibiltés variées d'utilisation des plastiques, leurs qualités d'adaptation, leur facilité de transformation et leurs avantages technologiques les ont fait rechercher, en particulier dans les secteurs d'activité touchant à l'emballage des denrées alimentaires et au conditionnement de l'eau. Afin de mieux comprendre les choix effectués pour préserver la santé de l'homme, on a rassemblé dans cet article les bases réglementaires, les procédures d'élaboration de la réglementation, son état d'avancement, ses perspectives, etc., dans les domaines d'application qui viennent d'être rappelés
