Physical methods for waste water treatment: The use of freeze/thaw method with the assistance of microwave radiation for oily water treatment / Fizičke metode za prečišćavanje otpadnih voda - primena metode naizmeničnog mržnjenja i hlađenja i mikrotalasnog zagrevanja za obradu zauljenih voda
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
The main sources of oily waste water are oil- refineries, metal industry and food industry. Any technological process that uses emulsions has to take into consideration also the treatment of the used emulsions. The ultimate ...
Water distribution system model calibration using genetic algorithm / Kalibracija matematičkih modela vodovodnih sistema primenom genetskog algoritma
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2008)
Model calibration is an important step in the modelling of water distribution systems. Since calibration is a process of adjusting model parameters so that model results fit best the measured data, it becomes a complex ...
Uncertainties in flood frequency estimation by partial duration series / Neizvesnosti u analizi velikih voda metodom parcijalnih serija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
In hydrologic practice, flood frequency analysis is usually based on fitting a theoretical distribution to observed data series. Flood frequency analysis in hydrologic practice is essentially based on fitting of a theoretical ...
Modified rainfall-runoff model for bifurcations caused by channels embedded in catchments
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2009)
The particularity of 'Vlasina' hydropower plants catchment is a big number of gravitation channels used to collect the water from neighboring natural catchments. The overall catchment size is thus increased, compared to ...
The Belgrade waste water system during severe rainfall / Beogradski kanalizacioni sistem u uslovima ekstremnih padavina
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The Belgrade waste water system started being built more than 100 years ago. It is getting larger in accordance to urban development aimed at collecting most of waste water including rainfall runoff and communal and ...
Demulsification based on the thermal treatment (cooling and heating) of W/O emulsions / Demulzifikacija naizmeničnim hlađenjem i zagrevanjem
(Savez hemijskih inženjera, Beograd, 2004)
An important step in waste water treatment is the removal of oil from an O/W emulsion and the separation of oil and water into two phases, a process usually called demulsification. Modern methods of oil removal from waste ...
The Belgrade sewage water quality parameters database development / Razvoj baze podataka parametara kvaliteta vode u Beogradskoj kanalizaciji
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2008)
In this paper the relational database development that represent the advanced solution for the Belgrade sewage water quality parameters warehousing is presented. Database is adjusted to the specific needs of the data ...
Problematika zaštite životne sredine u PD 'Elektrodistribucija Beograd'
(PD "Elektrodistribucija-Beograd", Beograd, 2007)
Zaključak: Zaštiti životne sredine u PD EDB treba posvetiti više pažnje u cilju organizovanja i formalizacije, odnosno potrebno je uvesti procedure ili uputstva za sprovođenje ZŽS. Postojeći kapaciteti za ZŽS u EDB-u su ...
Estimating double side-channel spillway capacity / Procena propusne moći dvostrukog bočnog preliva
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The capacity of the double side-channel spillway, consisting of the two spillways, with channels joining into a common single branch, is estimated in this paper. For the specific site conditions, such an arrangement may ...
Enhancement of digital elevation models for overland flow network delineation in urban catchments / Poboljšanje digitalnog modela terena za delineaciju površinskog tečenja na urbanim slivovima
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
Algorithms to prepare Digital Elevation Models (DMTs) for hydraulic analysis are common practice; these are often called DMT enhancement algorithms, and are frequently the first step of the analysis to extract overland ...
