Poplar wood sawdust was examined for adsorption as a replacement for current, more expensive methods of removing copper, zinc and cadmium from electroplating wastewater. Langmuir, Freundlich, BET and competitive Langmuir (two competing ions) isotherms were fitted to experimental data and the goodness of their fit for adsorption was compared. The shapes of(More)
This work presents kinetic parameters of the removal of hydrocarbons in the course of bioremediation of the soil contaminated with crude and oil derivatives, with special emphasis paid to polycyclic aromatic hydrocarbons. Bioremediation was carried out on a laboratory scale, with continuous and discontinuous recirculation of water through the soil column(More)
This study compares the effects of ozonation (0.4-3.0 mg O(3)/mg DOC) and TiO(2)-catalyzed ozonation - TiO(2)-O(3) (0.4-3.0 mgO(3)/mg DOC; 1.0 mgTiO(2)/L) at pH 6 on the content and structure of natural organic matter (NOM) and trihalometane (THM) and haloacetonitrile (HAN) precursors in groundwater. The investigated groundwater from Northern Serbia is rich(More)
The abilities of different types of wood sawdust and wood originate materials for removing some toxic heavy metal ions from water were investigated. Sawdust of poplar, willow, fir, oak and black locust wood, pulp and Kraft lignin were used as adsorbents. The effects of contact time, pH, metal concentration and sawdust particle size on the removal of Cu(II)(More)
The ability of seed extracts of several species of chestnut and acorn to act as natural coagulants was tested using a synthetic turbid water. Active components were extracted from ground seeds of Horse chestnut and acorns of some species of family Fagaceae: Common oak, Turkey oak, Northern red oak and European chestnut. All investigated extracts had(More)
The sawdust of oak and black locust hardwood was found to have good adsorption capacities for heavy metal ions. The leaching of coloured organic matters during the adsorption can be prevented by each of the following pre-treatments of adsorbents: with formaldehyde in acidic medium, with sodium hydroxide solution after formaldehyde treatment, or with sodium(More)
Formation of aldehydes and trihalomethanes during intermediate ozonation of water pretreated with ozone and polyaluminium-chloride was monitored in a pilot-scale study to optimize the drinking water treatment technology. The raw water was the groundwater, rich in natural organic matter, originated from the territory of the Northern Banat region in Vojvodina(More)
In the central Banat region (Northern Serbia), groundwater is used as a drinking water source. Raw water originates from a 40-80 m and 100-150 m deep layer. It contains a high amount of natural organic matter (DOC = 9.17+/-0.87 mg C/L) with a trihalomethanes formation potential of 448+/-88.2 microg/L and a haloacetic acid formation potential of 174+/-68.9(More)
The work presents kinetic parameters of the removal of the components with hydrocarbon functionalities and polar components in the course of bioremediation of the soil contaminated with crude and oil derivatives. In the course of a laboratory experiment that lasted 325 days it was found that content of the components with hydrocarbon functionalities(More)
The assessment of the quality of sediment from the Great Backi Canal (Serbia) based on the pseudo-total As and Cr content according to the corresponding Dutch standards and Canadian guidelines showed its severe contamination with these two elements. Microwave assisted BCR sequential extraction procedure was employed to assess their potential mobility and(More)
