Abstract

Voda je jedna od najvažnijih tvari u prirodi. Koristi se za ljudsku potrošnju, ali i za različite potrebe u industriji. Sukladno zahtjevima potrošača voda mora biti adekvatno pročišćena odnosno pripremljena. Za tu namjenu koriste se različite metode poput adsorpcije, membranske filtracije, reverzne osmoze i slično. Kao najefikasnija, najjednostavnija i ekonomski najisplativija metoda za pripremu vode pokazala se ionska izmjena. U ovom radu su kroz teorijski pregled obrađeni osnovni pojmovi vezani uz ionsku izmjenu. Prikazana je najosnovnija primjena ionskih izmjenjivača u tehnologiji vode, odnosno pri dekarbonizaciji, omekšavanju, demineralizaciji i denitrifikaciji vode. Osim toga, prikazani su osnovni načini regeneracije zasićenih ionskih izmjenjivača.

Abstract (english)

Water is one of the most important substances in nature. It is used for human consumption, but also for different needs in the industry. In accordance with the requirements of consumers, the water must be adequately purified or prepared. For this purpose are used different methods such as adsorption, membrane filtration, reverse osmosis and the like. Ion exchange has proved to be the most efficient, simplest and economically most cost-effective method for water preparation. In this final thesis through the theoretical review basic terms related to ion exchange have been elaborated. The most basic application of ion exchangers in water technology, i.e. decarbonisation, softening, demineralisation and denitrification of water is shown. In addition, basic methods of regeneration of saturated ion exchangers are shown.
