Abstract


Primarni cilj sistema vodosnabdijevanja je zaštita zdravlja ljudi obezbjeđivanjem mikrobiološki i hemijski ispravne vode za piće. Značajne promjene u kvalitetu vode izvorišta zahtjevaju dovoljno robusne sisteme pripreme vode za piće čije su performanse neosjetljive na date varijacije i promjenjive radne uslove. Mutnoća vode predstavlja važan parametar u kontroli filtracije vode i obezbjeđivanju efikasnosti dezinfekcije. U ovom radu ispitana je efikasnost uklanjanja mutnoće vode u fabrici vode za piće “Vodovod” u Banjaluci u toku uobičajenih uslova rada, kada je maksimalna detektovana vrijednost iznosila 25 NTU i vanrednih uslova rada u toku kojih je mutnoća vode dostizala vrijednost >240 NTU. Procjena robusnosti sistema bistrenja vode izvršena je pojedinačno za period uobičajenih i vanrednih uslova rada (u toku i nakon pražnjenja akumulacije). Za izračunavanje indeksa robusnosti korišćena je stroža ciljna vrijednost kvaliteta filtrirane vode (0,5 NTU) u odnosu na onu koja se zahtjeva aktuelnim zakonodavstvom, što u postojećoj praksi predstavlja novi kriterijum u analizi rizika. Rezultati obrade podataka ukazali su na visoku stabilnost rada tehnoloških jedinica u uobičajenim uslovima. Ustanovljen je značajan uticaj operativnih uslova fabrike na mutnoću filtrirane vode u vanrednim uslovima rada čija bi se optimizacija mogla izvršiti uz prethodan adekvatan monitoring izvorišta vode. Na taj način bi se smanjio potencijalni rizik od pojave patogena u vodi za piće.
