Changes in The Content of Biodegradable Organic Matter in Tap Water in The City of Częstochowa / Zmiany Zawartości Biodegradowalnej Materii Organicznej w Wodzie Wodociagowej Dla Miasta Częstochowy
This paper presents research aimed at the assessment of biodegradable organic carbon content changes (BDOC) during water disinfection process. The water samples examined in the research came from intakes, pumping stations at treatment plants situated in the Silesia district and water consumers. The examined water was underground water. One water sample was disinfected by sodium sub chloride while the other one by ozone. BDOC was determined using the Joret method, which involves observation of dissolved organic carbon (DOC) decrease in the examined water. The research has shown that BDOC content fluctuates at every stage of the treatment process and distribution of the examined water. Another analyzed parameter was biological stability of water.
