20.500.12556/DKUM-16556 MEMBRANSKA PILOTNA NAPRAVA ZA PRIPRAVO DEIONIZIRANE VODE MEMBRANE PILOT DEVICE FOR PREPARING OF DEIONIZED WATER Pri proizvodnji elektrike, v industriji elektronike ter farmaciji se pogosto deionizirana voda. To je filtrirana voda, ki vsebuje zelo malo kemijskih primesi ostalih elementov — je skoraj kemično čista voda. Za pripravo deionizirane vode se v zadnjem času vedno bolj uveljavljajo membranske tehnologije, kot so mikrofiltracija, ultrafiltracija, reverzna osmoza ter elektrodeionizacija. V praktičnem delu sem opisal celotno delovanje pilotne naprave z omenjenimi tehnologijami, ter sodeloval pri opravljanju fizikalno-kemičnih meritev na napravi z različnimi vodnimi viri. Opravil se je tudi teoretični izračun padca tlaka na membrane in primerava z izmerjenimi. Prikazan je pojav mašenja membrane za ultrafiltracijo ter izračun dodatne upornosti Rc. In the production of electricity, electronics and pharmaceutical industry is often use de-ionized water. This is the filtered water that contains very little chemical admixture of other elements - is almost pure water. For the preparation of deionized water the membrane technology is increasingly applied in modern use. Those technologies are microfiltration, ultrafiltration, reverse osmosis and elektrodeionization. In practical work I have described the overall operation of pilot plants with these technologies, and participated in the performance of the physico-chemical measurements on devices with different water sources. I also performed a theoretical calculation of pressure drop on the membrane and the solutions compered with the measured data. I present membrane fouling and calculated the resistance of membrane. membranske tehnologije ultrafiltracija reverzna osmoza flitriranje membrana elektrodeionizacija ionski izmenjevalci mehčanje vode deionizacija prevodnost deionizirana voda membrane technology ultrafiltration reverse osmosis electrodeionization membrane filtration water softening pilot device deionization conductivity deionized water true true false [U.
