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 ...
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 ...
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 ...
Rainfall runoff drainage and traffic safety in urban conditions / Odvođenje kišnog oticaja u gradovima i sigurnost saobraćaja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
The paper discusses the possibilities to evaluate the effects of applying different criteria for design of surface drainage systems on the reliability of these systems. The reliability is expressed using the safety faktor ...
Technical guidelines for fire water supply from public waterworks / Tehničke smernice za obezbeđivanje protivpožarne vode iz javnih vodovodnih sistema
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
In many European countries as well as in America there is no current common legislation requiring that public waterworks provide fire flows. Most public water supply systems provide fire water services to their community. ...
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 ...
Uncertainty of infrastructure leakage index (ILI) / O neodređenosti infrastruktuknog indeksa gubitaka - ILI
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
In many water systems, especially in developing countries, data on the elements of the system, flow measurements and water consumption have great uncertainty. This uncertainty in the further calculations is propagated to ...
Water mixing in reservoir and water age in the distribution network modelling / Modeliranje mešanja vode u rezervoaru i starosti u distributivnoj mreži
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
The main role of reservoirs is to store the water for periods when consumption is higher then water production, thus increasing the reliability of system. However, the water storage can also lead to water aging, and its ...
Late autmn bloom of potentialy toxic cyanobacteria Planktothrix rubescens in the multipurpose Vrutci reservoir / Jesenje cvetanje potencijalno toksične cijanobakterije Planktothrix rubescens u višenamenskoj akumulaciji Vrutci
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2014)
In December 2013th, the multipurpose Vrutci reservoir was the scene of potentially toxic cyanobacteria Planktothrix rubescens bloom. This paper presents the results of water quality field measurements that were conducted ...
Etaloniranje merne neodređenosti ravnih EM senzora
(Udruženje za tehnologiju vode i sanitarno inženjerstvo, Beograd, 2018)
Da bi se ostvarilo efikasno upravljanje hidrotehničkim sistemima neophodno je poznavati podatak o protoku. Merenje protoka u tokovima sa slobodnom površinom je generalno komplikovan zadatak koji zahteva znanja iz hidraulike ...
