Abstract
Reverzna osmoza je tlačni membranski separacijski proces koji se koristi u obradi voda. Najvaţniju ulogu ima u desalinaciji morske vode, u pročišćavanju vode za piće te obradi industrijskih voda. Jedan od fenomena, a ujedno i problema do kojeg dolazi u reverzno osmotskom procesu je pojava blokiranja membrana kojim se smanjuje propusnost membrane, čime se mora povećati tlak potreban za pokretanje procesa, a skraćuje se i ţivotni vijek membrana. Modifikacijom membrana moguće je poboljšati njihove performanse. U ovom radu prikazan je literaturni pregled najnovijih istraţivanja vezanih za modifikaciju komercijalnih reverzno osmotskih membrana kojima je cilj poboljšanje izvedbe membrana pri uklanjanju organskih spojeva iz vode. Linearni alifatski amini kao modifikatori membrane poboljšavaju izvedbu membrane pri uklanjanju bora, soli i N-nitrozamina iz vode, a polivinil alkohol smanjuje propusnost soli i rodamin boje.
Abstract (english)
Reverse osmosis is a pressure membrane separation process used in water treatments. It plays the most important role in seawater desalination, drinking water purification and industrial water treatment. One of the phenomenon, and at the same time the problem that occurs in the reverse osmosis process, is the occurrence of membrane fouling which reduces the permeability of the membrane, which means that the pressure nedded to start the process must be increased and the lifetime of the membranes is shortened. By modifying the membranes, it is possible to improve their performance. This paper presents a literature rewiew of the latest research related to the modification of the commercial reverse osmosis membranes; the goal of which is to improve the performance of the membranes when removing organic compounds from the water. Linear aliphatic amines as membrane modifiers improve the performance of the membrane while removing boron, salt and N-nitrosamines from the water while polyvinyl alcohol reduces the permeability of the salt and Rhodamine-WT.
