DRINKING WATER TREATMENT FROM SKORBA WATERWORKS

V diplomski nalogi smo želeli preveriti učinkovitost filtrnega sistema eSpringTM za čiščenje pitne vode. Po pregledu monitoringov pitne vode iz črpališča Skorba smo ugotovili, da so občasno presežene koncentracije pesticidov in neskladje mikrobioloških analiz z zakonodajnimi vrednostmi. Opravili smo fizikalno-kemijske in mikrobiološke analize vzorcev pitne vode iz Skorbe pred filtriranjem in po njem. Rezultati analiz so pokazali, da so bili pesticidi (atrazin, desetil-atrazin) v pitni vodi povišani, s filtrom eSpringTM pa se je njihova koncentracija znižala. Opravili smo mikrobiološke analize glede na vsebnost koliformnih bakterij, enterokokov in PseudomonasAeruginose. Rezultati so pokazali skladnost s pravilnikom o pitni vodi. Vseeno pa so mikrobiološke analize potrdile, da je filter eSpringTM učinkovit, saj je bila vsota mikroorganizmov v vseh vzorcih filtrirane vode manjša kot v nefiltrirani vodi.The aim of our thesis was to evaluate the quality of drinking water from the Skorba waterworks and to test the efficiency of the eSpringTM water purifier. We conducted the physico-chemical and microbiological analyses of treated and untreated drinking water samples in laboratory. Results of physico-chemical analyses were congruent with regulations on drinking water, except the concentrations of pesticides (atrazine, desethyl-atrazine) in drinking water which exceeded regulative values. After filtration with the eSpringTM water purifier the concentrations decreased below the regulative values. We observed the total number of coliform bacteria, the presence of Pseudomonas aeruginosa and enterococcus in drinking water samples. All microbiological analyses were in accordance with Slovene regulations on drinking water. However, the total number of microorganisms decreased in filtered water. We can conclude that eSpringTM water purifier further enhanced the quality of drinking water
