Abstract

Otpadna voda neželjeni je produkt svakog industrijskog procesa. Kako je voda veoma važan resurs, postoji potreba za njenom obradom i oporabom (ponovna upotreba). Jedna vrsta procesa koji se koriste u obradi otpadne vode su membranski separacijski procesi.
U ovome radu napisan je teorijski uvid o vrstama, karakteristikama i načinima provedbe istih. Kako se kod oporabe vode koriste tlačni membranski procesi, rad je baziran na njima.
To su mikrofiltracija (MF), ultrafiltracija (UF), nanofiltracija (NF) i reverzna osmoza (RO). Membrana, kao glavni dio ovih procesa, može biti izrađena od različitih materijala: organskih i anorganskih. Materijali se također mogu kombinirati i tako se stvaraju kompozitne membrane. Sve to omogućuje primjenu procesa pri različitim uvjetima te njihovu dobru selektivnost na određene kemijske vrste. U radu se opisuje primjena u proizvodnji pitke vode, prehrambenoj i tekstilnoj industriji te u obradi procjednih voda. Isto tako, prikazani su neki primjeri hibridnih procesa koji povezuju membranske separacijske procese s drugim procesima npr. koagulacijom i apsorpcijom.

Abstract (english)

Wastewater is an undesirable byproduct of any industrial process. As water is an extremely important resource, it must be treated and reused. One process used in wastewater treatment is membrane separation process. This paper gives a theoretical overview of the types, characteristics, and implementation methods of these processes. Since pressure-driven membrane processes are used in water reuse, the paper focuses on these. These include microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). The membrane as the main component of these processes can be made of different materials, including organic and inorganic ones. In addition, materials can be combined to produce composite membranes. As a result, the processes can be used under different conditions and offer good selectivity for specific chemical species. The paper describes applications in drinking water production, the food and textile industries, and in the treatment of landfill leachate. In addition, examples of hybrid processes are presented that combine membrane separation processes with other processes such as coagulation and adsorption.
