Hydraulic model study of turbulent flow measurement in sewer pipes conjunction / Hidraulička modelska ispitivanja merenja protoka na spoju kolektora sa silovitim tečenjem
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper presents capabilities and benefits of use of physical models for flow analysis in large sewer pipes and conjoining objects. A group of objects pertaining to the Belgrade Sewer System is modeled and results are ...
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 ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
The paper deals with modeling of two phase (water-air) flow in coarse porous medium, where, after reaching some air velocity, instability of the flow occurs. Firstly, a linear stability analysis has been conducted for ...
Numerical modeling of water temperature changes in reservoir Celije / Modeliranje sezonskih promena temperature vode akumulacije Ćelije
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
This paper presents the results of measurements and numerical modeling of water temperature changes in reservoir Celije in the period from April to October 2012. Reservoir Celije on the river Rasina, for many years attracts ...
Nitrate removal from water by biological denitrification / Biološka denitrifikacija u pripremi vode za piće
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2011)
Ground water pollution by nitrate from routine agricultural practices is a common and growing problem in the major agricultural areas of the world. The concentration of nitrates in these areas may exceed the maximal limited ...
Experimental investigation of transformation of micropollutants in biofilters: Raingardens / Eksperimentalno istraživanje transformacije mikropolutanata u biofilterima - raingardens
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
Biofilters (bio-retention ponds or rain gardens) are increasingly being used as a system for the storm water treatment in urban areas, because they manage to mitigate the peaks of storm rains and floods, and have shown ...
Mathematical modeling of the sewage system for improvement of the system and the WWTP in the Maribor city / Matematički model kanalizacionog sistema Maribora radi unapređenja kanalizacionog sistema i rada PPOV-a
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
This paper discuss conditions and constraints for WWTP operation using mathematical modeling of the sewage system for the city of Maribor. Using results of SWMM model accounting for various phases of urban surface runoff ...
Numerical modeling of two phase flow (water-air) after air injection into the water / Modeliranje dvofaznog strujanja (vode i vazduha) nakon utiskivanja vazduha u vodu
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
One of available lake restoration technologies is injection of compressed air or oxygen into a hypolimnion, promoting vertical mixing of water and dissolution of oxygen. A numerical model has been developed for simulation ...
Algorithm for water distribution network segmentation using existing isolation valves / Algoritam za segmentaciju vodovodne mreže pomoću postojećih izolacionih zatvarača
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
Dividing a complex water distribution network (segmentation) on smaller zones, with defined entry and exit points, is a precondition for better water loss management. In order to obtain these zones, often called District ...
Rainfall runoff drainage and traffic safety in urban conditions / Odvođenje kišnog oticaja u gradovima i sigurnost saobraćaja
