Abstract

Primjena membranskih procesa postaje sve dominantnija u tehnologiji obrade voda, a njihov razvoj i unapređenje nužan. Ultrafiltracija i reverzna osmoza predstavljaju dobro razvijene, korištene i poznate membranske metode koje su u svakodnevnoj upotrebi, kako na industrijskoj, tako i na kućnoj razini. Nanofiltracija je relativno nova membranska metoda koja kombinira poželjne karakteristike reverzne osmoze i ultrafiltracije. Primjer je inovacije u svijetu obrade vode. Ovaj rad fokusirat će se na osnovne karakteristike navedenih membranskih procesa, njihovu primjenu i prednosti u odnosu na ostale metode. Nadalje, rad pruža uvid u klasifikaciju nanofiltracijskih membrana i njihove karakteristike. Također, obrađene su najčešće i nadolazeće metode modifikacije nanofiltracijskih membrana. Modifikacija membrana provodi se radi optimizacije samih membrana kako bi se postigle bolje ili poboljšane membranske performanse uz minimalno žrtvovanje izvornih karakteristika membrana.

Abstract (english)

The application of membrane processes is becoming increasingly dominant in water treatment technology, and their development and improvement are necessary. Ultrafiltration and reverse osmosis represent well - developed, used and well - known membrane methods that are in daily use, both at the industrial and at home levels. Nanofiltration is a relatively new membrane method that combines the desirable characteristics of reverse osmosis and ultrafiltration. An example of innovation in the world of water treatment. This paper will focus on the basic characteristics of the mentioned membrane processes, their application and advantages compared to other methods. Furthermore, the work provides insight into the classification of nanofiltration membranes and their characteristics. Also, the most common and upcoming methods of modification of nanofiltration membranes are covered. Membrane modification is carried out in order to optimize the membranes themselves in order to achieve better or improved membrane performance with minimal sacrifice of the original characteristics of the membranes.
