Abstract

Rad pruža pregled različitih membranskih sustava koji se danas primjenjuju u obradi voda i uklanjanju zagađivala iz voda. Navedene su moguće konfiguracije, najčešće korišteni materijali u proizvodnji, čimbenici koji utječu na performanse, postupci čišćenja membrana i rukovanja otpadnim vodama. Membranski sustavi na principu napredne osmoze koriste razna osmotska sredstva za provođenje procesa. Modificiranjem PVDF-g-PSSA membrane je postignuta stabilnost u punom pH području. Razvijene su tankoslojne nanokompozitne membrane za nanofiltraciju s rGO/TiO2 nanokompozitom koje pokazuju odlično uklanjanje soli i visok fluks vode. Fotokatalitički membranski reaktori se dijele na reaktore s imobiliziranim i suspendiranim fotokatalizatorom. Ovaj rad omogućava uvid u mogući smjer daljnjeg razvoja i mogućnosti koje pružaju nove membrane u tehnologiji desalinacije.

Abstract (english)

This paper offers a review of various membranes that are applied now days in water treatment and pollutant rejection. Possible configurations, most commonly used materials in production, performance influencing factors, cleaning methods and wastewater management are listed. Forward osmosis membranes use different draw solutions to conduct the process. Full pH-stability is achieved by modifying the PVDF-g-PSSA membrane. Thin film nanocomposite nanofiltration membrane with rGO/TiO2 nanocomposite are developed which show excellent salt rejection and high water flux. Photocatalytic membrane reactors are divided into reactors with immobilized and suspended photocatalyst. This work provides an insight in potential direction of further development and capabilities of novel membranes in desalination technology.
