RECYCLING OF WASTE SLUDGE FROM WWTP “GORIĆ” VALJEVO USING THE PROCESS OF STABILIZATION AND SOLIDIFICATION
The efficiency of wastewater treatment is not only measured by the quality of treated wastewater, but also by the efficiency of treatment and permanent disposal of sludge that is separated. In addition to harmless, the sludge also contains hazardous substances that are released from wastewater during treatment. This work aims to obtain a neutral an...

THE MECHANISM OF THE EFFECTS OF INCREASING THE LENGTH OF THE PILES UNDER LATERAL LOADS IN SAND
In many projects, piles are designed and installed as the ultimate solution in foundation construction, load transition to the resistant subsurface layers, providing lateral resistance, and overcoming the poor performance of surface soils. Pile design should be done with respect to structural consideration, the load-carrying capacity of the surface...

DEVELOPMENT OF A METHODOLOGY FOR STABILITY MONITORING OF A DEFENSE EMBANKMENT LOADED WITH FREQUENT TRAFFIC: THE EXAMPLE OF THE KOVIN MINE
In the present paper, the authors develop a methodology for stability monitoring of the hydrotechnical-defensive embankment that is exposed to heavy frequent traffic. The proposed methodology envisages several phases of observation, work and monitoring: (1) macroscopic observations, (2) geophysical-geoelectric tests, (3) group of exploration works,...

IMPACT ANALYSIS OF THE BANJA LUKA-DOBOJ MOTORWAY CONSTRUCTION ON THE QUALITY OF WATERCOURSES WITH A LOWER RECEIVING CAPACITY
Prevention of the surface water quality deterioration as a result of motorway construction or similar anthropogenic activities is certainly a rather more demanding task relating to watercourses with lower flow rates than larger watercourses. The paper presents the impact of part of the Banja Luka - Doboj motorway construction site, notably section ...

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 ...

CRACK RESISTANCE OF REINFORCED CONCRETED AND REINFORCED RUBBER CONCRETE BEAMS
The issue of the appearance and development of cracks, as well as an increase the cracking moment is of particular importance for bending elements operating under aggressive environmental conditions. In structures without cracks, steel reinforcement operates in fairly favorable conditions. However, when cracks appear in the sections of the structur...
