Abstract

V diplomskem delu smo raziskali možnost uporabe za pripravo kopalnih vod. Izbrali smo tri vzorce vod: morsko vodo, vode iz reke Drave in vodo iz kompenzacijskega bazena kopališča Fontana. Med procesom elektrokoagulacije smo opazovali spreminjanje temperature, električnega toka, pH in prevodnosti ter njihov vpliv na sam proces elektrokoagulacije. Vse parametre smo opazovali v odvisnosti od časa in pri konstantni električni napetosti za posamezni proces. Po koncu vsakega procesa smo izmerili motnost in absorbanco. Glede na ta dva parametra smo ugotovili, da dobimo pri reki Dravi najboljše rezultate pri električni napetosti 30,5 V, pri morski vodi 3,0 V in bazenski vodi 4,0 V. V vodi iz reke Drave smo po 45 min elektrokoagulacije uspeli znižati motnost za 90,1 %. Pri morski vodi se je motnost po 30 min zmanjšala za 79,3 % in pri bazenski vodi po 25 min za 92,6 %. Opravili smo tudi mikrobiološke analize za bakterijo Escherichia coli, katere rezultati so pokazali ustavitev rasti bakterij pri obdelani vodi iz reke Drave, medtem ko se je pri morski in bazenski vodi v po obdelavi razvilo več bakterij kot v neobdelani vodi. Ugotovili smo, da je elektrokoagulacija primerna za čiščenje tipa vod, kot je voda iz reke Drave, kjer je nizka električna prevodnost in se izloča majhna količina aluminija, medtem ko za vode tipa morske in bazenske vode ni primerna.

Secondary abstract:	This thesis studied the effectiveness of electrocoagulation using aluminum electrodes for the bathing water conditioning. Three water samples were chosen: seawater, water from the river Drava and the pool water from Fontana spa. During the process of electrocoagulation, the changing temperature, electric current, pH and conductivity as well as their impact on the process itself were observed. All parameters were monitored as a function of time and at a constant voltage for a particular process. After completion of each process we measured turbidity and absorbance. These two parameters were found to give the best results on the river Drava at a voltage of 30.5 V, the sea water at a voltage of 3.0 V and the pool water at a voltage of 4.0 V. We managed to reduce the opacity by 90.1 % in the river Drava after 45 min of electrocoagulation. In the case of sea water after 30 minutes of the electrocoagulation turbidity decreased by 79.3 % and in pool water after 25 minutes by 92.6 %. We also performed microbiological analyses for Escherichia coli and the results showed inhibition of the bacteria growth in the treated water from the river Drava. In the case of sea and pool water in the treated water has bacteria grown in comparison with untreated water. We have found out that the electrocoagulation is suitable for conditioning of water such as water type from river Drava, where there is low electrical conductivity and a small amount of aluminum is excreted. However, it is not suitable for the type of sea water and pool water because they secrete large amounts of aluminum.
