AB  - Acid mine drainage is a challenging environmental problem caused by mining activities. Long-term  copper  ore  exploitation  and  vast  amounts  of  mining  waste  lead  to  severe  soil  contamination as well as river and groundwater pollution. In this paper, research is focused on utilizing waste mine waters and off-balance parts of the mine deposit (such as flotation tailings) and converting their negative characteristics to an environmentally friendly one. In the  authors’  previous  work,  acid  mine  water  from  Robule,  which  is  part  of  the  Bor  copper  mining and smelting complex in Serbia, was successfully treated using flotation tailings, and the resulting solution was suitable for safe discharge. This paper investigates the characteristics of the solid residue that remained after the treatment of the modified flotation tailings in order to  evaluate  the  possibility  of  its  safe  disposal  back  into  the  environment.  The  solid  residue  was subjected to TCLP and EN 12457-4 tests as standard procedures that assess the leaching characteristics  of  a  material.  The  solid  residue  was  also  exposed  to  long-term  leaching  with  melted  snow  to  simulate  environmental  conditions  for  one  year.  This  drainage  water  was  analyzed and compared with the results of the standard leaching procedures. The investigated treatments lead to improved economic and environmental effects, while the process itself is adjusted to preserve the environment.

AB  - A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2 center dot 5H(2)O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer-Emmett- Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC's sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g(-1) , and 131 mg g(-1) respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudosecond kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation-pi interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

AB  - Acid mine drainage (AMD) is a waste from mining sites, usually acidic, with high concentrations of sulfates and heavy metal ions. This study investigates the AMD neutralization process using fly ash (FA) as an alternative material. Samples of FA from coal-fired power plants in Serbia ("Nikola Tesla" (EF) and "Kostolac" (KOST)) were analyzed and used. The results were compared with the treatment efficiency of commercial neutralization agent (NaOH). The alkaline nature of FA was the basis for use in the treatment process of the extremely acid Lake Robule (pH 2.46), located in the mining areas of eastern Serbia. The optimal S/L ratio for the AMD neutralization process determined for EF was 25 wt.%, and for KOST it was 20 wt.%. The mechanism of the neutralization process was analyzed using the ANC test and PHREEQC program. The element concentrations and pH values in solutions indicated that FA samples could neutralize Lake Robule with more than 99% of Al, Fe, Cu, Zn, and more than 89% of Pb precipitated. Formation of insoluble (oxy)hydroxide forms (Fe3+ and Al3+ ions) creates favorable conditions for co-precipitation of other trace metals (Cu, Zn, Ni, Pb, and Cd) from AMD, which is further enhanced by cation adsorption on FA particles. FA proved to be a more effective neutralization agent than NaOH due to its adsorption effect, while among the FA samples, KOST was more effective due to the aging process through the carbonization reaction. Using FA as an alternative material is a promising and sustainable method for treating AMD, with economic and environmental benefits.

there are problems with wastewater from production that needs to be addressed in an

harmful substances, thereby reducing its pollution level, and at the same time, it also has a certain

pollutants are of organic origin and their removal will be carried in this work out using advanced
oxidation processes using ozone, and ozone in combination with ultrasound to achieve water
quality that complies with the law. The purification process will be optimized with respect to,
method, time and amount of oxidizing agent applied. The degree of pollution of water by organic
