Abstract

U suradnji s Vodovod i kanalizacija d.o.o. Karlovac istraživana je kakvoća vode rijeke Kupe na ispustu uređaja za pročišćavanje otpadnih voda (UPOV) grada Karlovca i Duga Rese. Uspješnost UPOV-a u uklanjanju dušika (N) iz otpadne vode izračunata je iz podataka o koncentraciji N tijekom 2021. godine ustupljenih od strane Vodovoda i kanalizacije d.o.o. Karlovac. Provedene su analize odabranih pokazatelja kemijske kakvoće vode (pH, E.C., NO3- i NH4+) u uzorcima prikupljenim u razdoblju od 24. 04. 2022. do 28. 05. 2022. godine iz rijeke Kupe, i to s četiri lokacije odabrane s obzirom na udaljenost od ispusta pročišćivača: 100 m uzvodno, na ispustu, 1 m nizvodno i 100 m nizvodno od ispusta pročišćivača. UPOV prosječno uklanjanja 80,73 % ukupnog N iz otpadne vode. Praćeni pokazatelji kakvoće vode bili su unutar graničnih vrijednosti prema Pravilniku o graničnim vrijednostima emisija otpadnih voda (NN 26/2020) te je zaključeno da se ne očekuje značajan utjecaj na ekološko stanje rijeke Kupe.

Abstract (english)

In cooperation with Waterworks and Sewerage Ltd. Karlovac, water quality of the Kupa River was studied at the outlet of Wastewater Treatment Plant (UPOV) of the City of Karlovac and Duga Resa. Wastewater Treatment Plant efficiency in removing total nitrogen (N) from wastewater was calculated for the year of 2021 from data provided by Waterworks and Sewerage Ltd. Karlovac. Selected water quality indicators (pH, E.C., NO3- and NH4+) were measured from April 24th untill April 28th, 2022, in Kupa River water samples taken from four locations varying in distance from Wastewater Treatment Plant outlet, i.e., 100 m upstream, at the outlet, 1 m and 100 m downstream from the outlet. The Wastewater Treatment Plant removes on an average of 80,73 % of total N from wastewater. Measured water quality indicators were within the limit values according to the Regulation on limit values for wastewater emissions (NN 26/20). No significant impact on ecological status of the Kupa River is expected.
