The Eficiency of Resita Town Water Treatment Plant

The main source of water supply for the residents of Resita town is Birzava River. Water is extracted from the settling basin of Crainicel Hydroelectric Power Plant located on Birzava River, upstream of Resita town. The water treatment station, with 1 m3/s discharge contains in its technological line the following items: kitchen reagents, reaction tanks, clarifiers, filters, chlorine disinfection and storage tanks. Water quality measurements, at the entrance and exit of water treatment plant were made for a two year period (2010 2011). Analyzed quality parameters in this paper are: water turbidity, pH, water oxidation, ammonium, nitrate concentrations. The average yield reduction of presented parameters was between 1.93 (for pH)), and 49.61 (for ammonium). The comparison of values from analyzed parameters at the exit of water treatment plant with the current regulation ones for drinking water allowed us to conclude that the supplied water to residents of Resita town corresponds in terms of quality, to a good quality drinking water.
