CHEMICAL LEACHING OF CONTAMINATED SOIL – CASE STUDY
This study presents results of chemical leaching of contaminated soil from several metallurgically loaded locality of Richnava in Slovakia, applying two chelants – Na2EDTA and Na3EDDS of different molar concentration, done at different leaching conditions. The lower molar concentration (2 mM) of chelants showed comparable effect on Mn, Ni, As...

COMPETITIVE ADSORPTION OF CR(VI), K(I) AND NH4(I) IONS ONTO NATURAL ZEOLITES AND BENTONITES
Chromium, ammonium, and potassium compounds are pollutants in the environment released mainly by industrial wastewater and they can negatively influence the quality of surface water. Zeolites and bentonites are commonly used adsorbents for removal of pollutant from water. In the study, the adsorbents were used in their natural form, without chemica...

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...

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...
