Drinking water quality in Podgorica [Montenegro, Serbia&Montenegro] - dependence of chlorination by products concentration on the organic matter in water
2003
Karajic, M. | Djurovic, D. (Institut za zdravlje Crne Gore, Podgorica (Serbia and Montenegro))
Presentation is dealing with data on raw and drinking water quality of water supply sources and water supply systems in Podgorica, Montenegro (Serbia&Montenegro). Special attention was paid to organic matter content, concentration of disinfectants and disinfection by-products. Average values of all parameters examined are below maximum permissible levels defined by regulations. That means that physical-chemical quality of water is excellent.

Nowadays people increasingly use bottled water for drinking which makes bottling a very profitable business. The aim of this paper is better understanding of physical and chemical properties as well as the contents of dominating ions and microbiological purity of 13 spring waters existing on the territory of Zlatibor region (Serbia, Serbia&Montenegro) which according to its water capacity, its watershed features and good roads availability may be further explored for the purpose of water bottling.

Cubrilo, D. | Zelic, J. | Dolga, M. (Zavod za zastitu zdravlja, Sombor (Serbia and Montenegro))
Having known the fact that on the territory of West-Backa region the only water used for water supply system is subterranean water, from different water layers, an assumption can be made that the waters also differ in their physical and chemical content. It is also assumed that these waters differ in their total iron content. The aim of this work is to test the significance of the difference between central water supply systems of West-Backa region (Sombor, Apatin, Kula and Odzaci) for the value of iron in drinking water, using the adequate statistics methods. The central water supply systems in Sombor, Apatin, and Kula are using water from the second water layer (60-75 m), while the water supply system in Odzaci is using deep artesian and subartesian waters (146-220 m). Sombor and Apatin have the raw water purification system and one of the goals is to decrease the concentration of total amount of iron in drinking water.

Cibulic, V. (Zavod za zastitu zdravlja, Leskovac (Serbia and Montenegro)) | Perisic, M. (Geo institut, Beograd (Serbia and Montenegro))
The results of a study on the water of the Sumanka river during several years point out the decrease in its quality. The results of the present study show that the technological actions, as well as the some technical changes, carried out in the Lebane's plant in Grgurovci gave the satisfactory effects. Turbidity, colour, KMnO4 demand and ammonia are efficiently reduced, along with low concentrations of Fe, Mn, and residual Al, ensure completely the water standard quality in accordance with the Protocol.

Milenkovic, P. | Marusic, V. | Lucic, G. (Zavod za zastitu zdravlja "Timok", Zajecar (Serbia and Montenegro))
Author described the beginnning of organized supply Zajecar, Serbia (Serbia&Montenegro) with drinking water and the establishment of Public Firm for Water Supply. In this paper author shows the results of five-years analysis of drinking water and the influence of water quality on human health during this period of organized supply with water.

According to existing national Standard for drinking water quality NO3 sup(-) ion is limited to 50 mg/l. Removal of NO3 sup(-) concentration greater than this limit is necessary. One of the possible methods is biological denitrification with CH3OH. Principals of this method are described in this paper with recommendation for construction of pilot plan on the specific groundwater source.

Agbaba, J. (Prirodno-matematicki fakultet, Novi Sad (Serbia and Montenegro). Departman za hemiju) | Dalmacija, B. | Klasnja, M. | Ivancev-Tumbas, I.
The paper deals with pilot-scale investigations of the effect of preozonation on NOM removal from groundwater by coagulation and flocculation processes. It was found that the preozonation increased the efficiency of organic matter removal by coagulation and flocculation from 23.6 to 47.2% as judged on the basis of KMnO4 values. From the aspect of the change of content of trihalomethanes precursors preozonation exhibits both the positive and negative effects if their content in the water after coagulation is considered in dependence of the applied ozone dose. The obtained values siggest the necessity of careful optimization of the processes of preozonation, coagulation, and flocculation, especially from the aspect of the change in content of the precursors of disinfection byproducts.

2003
Milenkovic, P. (Zavod za zastitu zdravlja "Timok", Zajecar (Serbia and Montenegro)) | Nakic, S. | Bajic, A. | Radosavljevic, M.
The lack of drinking water in Zajecar was the main reason for building of water barrier on the Grliste river and making the water reservoir. A factory for water processing was also built, but the problems were not disappeared. The conclusion is that the main solution for this ecosystem was in establishing of an monitoring system. That is the reason why we talk out the results of the monitoring and the troubles in this water source as well as in the phases of water processing.

Boreli-Zdravkovic, Dj. | Radenkovic, Z. (Institut za vodoprivredu "Jaroslav Cerni", Beograd (Serbia and Montenegro))
Concentrations of nitrate above defined levels for portable water are present in most of the groundwater sources in Velika Morava river alluvion. Some problems exists in Meminac and Kljuc, groundwater sources of Pozarevac town. Some detail investigations were organized in 2002. Survey of groundwater quality in the wide surrounding of Kljuc confirmed some earlier made assumptions about influence of agriculture and sewage water, and their contribution to existing groundwater quality.

Cakic, B. | Popovic, L. | Ljuboja, M. | Svrkota, D. (Institut za vodoprivredu "Jaroslav Cerni", Beograd (Serbia and Montenegro))
Membrane processes is gaining broad application in potable water treatment. Experience in application of membrane system for treatment of potable water so far showed that these systems have wide range of advantages versus conventional treatment: lower capital costs, lower operation costs, use of chemicals is minimal; space for installation is much smaller, usage of chlorine for disinfection is minimal due to significant reduction of microorganisms; sludge production during the process is smaller due to smaller usage of chemicals, construction period is shorter due to smaller scope of works and relatively simply installation of membrane batteries.
