20.500.12556/DKUM-55448 UGOTAVLJANJE TRDOTE VODE IN IZLOČANJE VODNEGA KAMNA ASSESSMENT OF WATER HARDNESS AND SCALE FORMATION V magistrskem delu smo preučevali problematiko izločanja vodnega kamna iz vode na črpališču v Sp. Ščavnici. Izmerili smo relevantne fizikalno-kemijske parametre. Na podlagi rezultatov meritev smo se odločili za elektromagnetno napravo in permanentni magnet, ki na kristalizacijo vodnega kamna vplivata z magnetnim poljem. Izvedli smo eksperimente pri različnih variantah montaže elektromagneta in pri različnih obtokih vode skozi merilno progo. Dokazali smo, da se brez obdelave iz vode izloča kalcit, medtem ko se aragonit izloča v manjši meri. Po obdelavi z elektromagnetom in permanentnim magnetom pa se delež aragonita poveča. Pri tem zadostuje že par obtokov skozi napravo. Pomembna ugotovitev je, da se po obdelavi kemijska sestava vode in mikrobiološka slika ne spremenita. In master´s work we studied the issue of limescale formation in the water at the pumping station in Sp. Ščavnica. We measured the relevant physico-chemical parameters. Based on the measurement results, we decided to use electromagnetic device and permanent magnet, which influenced on the crystallization of lime with a magnetic field. We carried out experiments with different variants of assembly of the electromagnet and at different ways of water circulation through the magnetic device. We have shown that without any water treatment the calcite precipitated, however aragonite at lesser extent, while after the treatment with either electromagnet or permanent magnet, the proportion of aragonite increased only after a few re-circulations of water through the device. An important finding is that after the treatment the chemical and microbiological content did not change. vodni kamen trdota vode magnetna obdelava vode permanentni magnet elektromagnet pitna voda scale water hardness magnetic water treatment permanent magnet electromagnet drinking water true true false [N.
