Abstract

U današnje vrijeme sve češće se susrećemo s pojmom klimatskih promjena u naslovima članaka, na televiziji i na društvenim mrežama. Pojam klimatske promjene sa sobom veže i problem nedostatka pitke vode. Potencijal dobivanja pitke vode iz morske vode procesom desalinacije najperspektivnije je rješenje problematike nedostatka pitke vode, pogotovo u sušnim područjima. U ovom radu naglasak je na novoj metodi priprave membrana za desalinaciju putem 3D tehnologije, metodama aditivne tehnologije i vrstama membrana za desalinaciju. Metode aditivne tehnologije na kojima će se bazirati novi primjeri membrana su selektivno lasersko sinteriranje (SLS) na bazi praha, digitalna obrada svjetlom (DLP) temeljena na fotopolimerizaciji (fotoočvršćivanje) te tiskanje elektrosprejom. 3D tehnologija trenutno je u razvoju pa se još uvijek koriste konvencionalne metode priprave membrana jer su povoljnije od neistraženih i skupocjenih istraživanja novih metoda izrade membrana. Kroz rad su naglašene prednosti koje nosi 3D ispis membrana te važnost u pogledu čim boljih karakteristika membrana poput zadržavanja soli i propusnosti vode. Neke od prednosti 3D ispisa su brzina izrade, automatizacija i veća ekološka prihvatljivost.

Abstract (english)

Nowadays, we encounter the term climate change more and more often in the titles of articles, on television and in social networks. The concept of climate change brings with it the problem of lack of drinking water. The potential of obtaining potable water from seawater through the desalination process is the mostpromising solution to the problem of the lack of potable water, especially in arid areas. In this paper, the emphasis is on a new method of preparing membranes for desalination using 3D technology, methods of additive technology and types of membranes for desalination. Additive technology methods on which the new examples of membranes will be based are powder-based selective laser sintering (SLS), digital light processing (DLP) based on photopolymerization (photocuring), and electrospray printing. 3D technology is currently under development, therefore membranes made by conventional methods are mostly used because they are more favorable than the unexplored and expensive research of new methods of making membranes. The work will emphasize the advantages of 3D printing of membranes and the importance of better membrane characteristics such as salt rejection and water permeability. Some of the advantages of 3D printing are production speed, automation and greater environmental acceptability.
