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 ...

ESTIMATING THE INFLUENCE OF SOLAR RADIATION AT DIFFERENT SEASONS ON THE MODE OF DEFORMATION OF A SPAN STRUCTURE WITH AN ORTROTROPIC PLATE
The article studies the effect of solar radiation at different seasons on the mode of deformation (MD) of a span structure with an orthotropic plate. The temperature fields of the elements of the structure were measured during daylight hours at different times of year at various air temperatures and sun positions. Cases were identified in which it ...

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...

APPLICATION OF NEW TECHNOLOGIES IN THE WATER SUPPLY SYSTEM
Freshwater water resources are not inexhaustible [1]. In recent decades, more and more facts point to this statement from the European Charter for Water. Uncontrolled drinking water interventions, losses in water supply and climate change indicate the problem of sufficient quantities of drinking water [2]. Looking at this problem, it is hard to bel...
