| Popis: | Cilj ovoga rada je statističkom obradom analitičkih izvješća o kakvoći vode za ljudsku potrošnju uzorkovanoj iz vodoopskrbne mreže grada Osijeka i prigradskih naselja tijekom desetogodišnjeg razdoblja (2009.-2018.godine) utvrditi učinkovitost ispiranja gradske vodoopskrbne mreže na kakvoću vode koja se distribuirala potrošačima putem vodoopskrbne mreže. Podaci za analizu su ustupljeni od tvrtke Vodovod-Osijek d.o.o. Osijek. Obradom i prikazom navedenih podataka praćena je kakvoća vode prije i po završetku ispiranja na različitim lokacijama vodoopskrbne mreže. Učinkovitost ispiranja mreže praćena je analizom podataka o koncentraciji željeza (μgFe/l), mutnoći (◦NTU) i boji vode (◦Pt Co skale). Korelacijom i grupiranjem dobivenih podataka ovisno o dijelu godine (prije i nakon ispiranja mreže) utvrdila se i ovisnost kakvoće vode u vodoopskrbnom sustavu o udaljenosti od pogona za proizvodnju vode kao i protoku i potrošnji vode. Temeljem dobivenih podataka dana je ocjena učinkovitosti ispiranja vodoopskrbne mreže. The aim of this paper is to determine the efficiency of rinsing the drainage of the city water supply network and the quality of the water distributed to consumers via the water supply network through the statistical analysis of the analytical reports on the quality of water for human consumption sampled from the water supply network of Osijek and suburban settlements during the ten year period (2009-2018). The data for the analysis were handed over by Vodovod-Osijek d.o.o. Osijek. Using statistical method data of water quality before and after the rinsing in different water supply locations is processed and monitored. The netting efficiency was monitored by analyzing iron concentrations (μgFe / l), turbidity (◦NTU) and water color (◦Pt Co scales). Correlation and grouping of the data obtained depending on the part of the year (before and after rinsing the network) also determined the water quality dependence in the water supply system on the distance from the water production plant as well as the flow and water consumption. Based on the results it is possible to conclude whether rinsing the water supply network is necessary to perform on annual level or is it only necessary in certain cases on the critical points of the network. |
