IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Constructed wetlands aplication in eco-hydrological conditions of vojvodina province

ABSTRACT
Constructed wetlands are manmade wetlands built to remove various types of pollutants that may be present in water
that flows through them. They possess a rich microbial community in the sediment to effect the biochemical
transformation of pollutants, they are biologically productive, and most importantly, they are self-sustaining.
Unfortunately, this popular method still is not applied wider in our country. The two attempts are just going on in
Vojvodina Province. This paper deals with details of two constructed wetland, in Glozan, and in Novo Milosevo. Glozan
is a village with 2275 people, and with sewage system, without any industry inflow. Total area of the wetland system of
8400 m2 is divided into three ponds: settling pond, purification pond, and the pond improvement of treatment effects.
The sewerage system of the settlement of Novo Milosevo has been constructed for treatment of the municipal waste
waters, assuming 8450 equivalent inhabitants. Treatment of waste water is carried out in several stages that are by
passing it through the following sections: primary treatment lagoon, pre-wetland, primary wetland, secondary wetland,
and tertiary wetland.
The wetland systems in Glozan and Novo Milosevo appeared to be efficient in removing suspended matter, and lowering
content of organic matter. Removal of nitrogen matter is also significant, as well as in the removal of phosphorus. The
system efficiency is also associated with the role of micro organisms and plant species involved in the wetland, usually
common reed. Best results are achieved under optimum conditions of the environment for the micro organisms and
plants, i.e. in summer and autumn. It was found that the Glozan wetlands retain in average 293 kg P/year and 2924 kg
N/year. The results showed that these elements are taken up by plants.
The water balance and the results of pollutants removal confirm that the systems of constructed wetlands may be used
under the eco-hydrological conditions of Vojvodina
