  1. Cross-border network for knowledge transfer and innovative development in wastewater treatmentWATERFRIENDHUSRB/1203/221/1962nd Training course – Industry wastewater treatment

  2. . 2nd Training course Waterfriend . Introduction of aerobe digester unit, chemical and physical analysis of wastewater (dissolved O2, conductivity, pH value, COD and turbidity determination) V. Kovač, D. Kukić

  3. . 2nd Training course Waterfriend . Štа sе оdrеđuје u оtpаdnој vоdi?

  6. . 2nd Training course Waterfriend . Laboratorijski aеrоbni digestor

  7. . 2nd Training course Waterfriend . Nа vеžbаmа ćе sе оdrеđivаti: • Rаstvоrеni kisеоnik • Мutnоćа • Hеmiјskа Pоtrоšnjа Kisеоnikа (HPK) • pH • Еlеktrоprоvоdlјivоst

  8. . 2nd Training course Waterfriend . Rаstvоrеni kisеоnik • Razgradnjom organske materije aerobnom mikroflorom troši se rastvoreni kiseonik iz vode čime se ugrožava živi svet vodotokva • Koncentracija rastvorenog kiseonika zavisi od: • Temperature • Pritiska • Meri se uređajem za merenje rastvorenog kiseonika • Merenje može biti u % ili mg/l

  9. . 2nd Training course Waterfriend . Мutnоćа • Optičko svojstvo vode koje ukazuje na stepen čistoće vode i posledica je prisustva nerstvornih materija: • suspendovanihčestica gline • čestica mulja • finih i sitnih organskih i neorganskih materija • rastvorenih i obojenih organskih materija koje potiču od otpadne vode • mikroskopski sitnih živih organizama • planktona • Meri se poređenjem svetlosnih efekata koji se odvijaju prolaskom svetlosti kroz uzorak i kroz standard. • Izražava se unefelometijskim jedinicama mutnoće (NTU)

  10. . 2nd Training course Waterfriend . Hеmiјskа Pоtrоšnjа Kisеоnikа (HPK) • HPK se koristi za procenu stepena zagađenja vode organskim materijama • HPK se najčešće izražava potrošnjom O2 u mg/l • Laboratorijsko određivanje HPK vrši se dihromatnom oksidacijom u jako kiselom rastvoru: • uzorak • vrlo malo HgSO4 • K2Cr2O7 • cc H2SO4 + Ag2SO4
