Abstract
U ovom radu proučavano je blokiranje ultrafiltracijske ZW - 1 membrane u obliku šupljih vlakana prilikom obrade otopine natrijeva sol alginatne kiseline. Navedena otopine predstavljala je simulaciju sekundarnog efluenta u kojem se nalaze polisaharidi kao blokirajuće tvari, te ispitan utjecaj koncentracije kalcijevog iona i pH vrijednosti na blokiranje. Nađeno je da u kiselim uvjetima (pH = 4) blokiranje ultrafiltracijske membrane u obliku šupljih vlakana veće. Također utvrđeno je da porastom koncentracije natrijeve soli alginatne kiseline blokiranje membrane jače. Porastom koncentracije kalcija stvorio se gel polimera alginata na površini membrane. Modeliranjem blokiranja utvrđen je mehanizam djelomično blokiranje pora (n = 1).
Abstract (english)
In this work, blocking of the ultrafiltration ZW - 1 membrane in the form of hollow fibers was studied during the processing of the solution of the sodium salt of alginic acid. The above solutions were a simulation of a secondary effluent containing polysaccharides as blocking agents, and the effect of calcium ion concentration and pH on blocking was examined. In acidic conditions (pH = 4), the blocking of the ultrafiltration membrane in the form of hollow fibers was found to be greater. It was also found that with increasing concentration of the alginic acid sodium salt, membrane blocking was increased. An increase in calcium concentration has created a gel of alginate polymers on the membrane surface. By blocking modeling, the mechanism was partial pore blocking (n = 1).
