UNEVENNESS OF WATER CONSUMPTION IN SETTLEMENT ON THE CASE OF DOBOJ

Water consumption in a settlement is an extremely variable size that changes constantly over time. Changes in water consumption occur on an annual, monthly, weekly, daily and hourly basis, and depend on many factors such as: climate, season, temperatures, hours of work, consumer habits, etc.Extreme value of consumption, ie. the peak hour flow is de...

COLUMN SORPTION OF TOXIC IONS IN VARIOUS QUARTZ SAND - PACKED COLUMNS

In this study the adsorption of As(V), Cu(II) and Zn(II) ions from multi-species model solution was tested in dynamic conditions in sand columns containing a thin layer of bentonite (B), iron-based sludge (IS) and synthetic magnetic particles (MP). Adsorption experiments were performed in order to evaluate the removal efficiency and selectivity of ...

SOIL AND RADIONUCLIDES OF EASTERN HERZEGOVINA

Soil is one of the most important natural resources. Measurement of natural radioactivity in soil is very important to determine the amount of change of the natural background activity with time as a result of any radioactivity release.Coal mine and thermal power plant in Gacko field is a very important industrial facility. The content of radionucl...

ELIMINATION OF TOXIC ELEMENTS BY NATURAL AND SYNTHETIC ADSORBENTS

The adsorption of Zn(II) and Cu(II) onto siderite (S) and kaolin (K) and adsorption of As(V) onto bentonite (B) was studied. The chemical modification – precipitation of MnO2 on the kaolin (KM) and siderite (SM) surface was used to improve the adsorption properties of natural materials for their application in columns. In the batch tests the higher...
