Abstract:
... The removal of benzene (B) and toluene (T) from aqueous solution by multi walled, single walled, and hybrid carbon nanotubes (MWCNTs, SWCNTs, and HCNTs) was evaluated for a nanomaterial dose of 1 g/l, concentration of 10-100 mg/l, and pH 7. The equilibrium amount removed by SWCNTs (B: 9.98 mg/g and T: 9.96 mg/g) was higher than for MWCNTs and HCNTs. Toluene has a higher adsorption tendency on CNTs ...

Abstract:
... One of the methods of sewage sludge disposal, which is based on its fertilizing properties, is its use in nature, e.g. in farming (if all the permissible standards are met). However, the sludge used for soil fertilization might also contain heavy metals, pathogenic microorganisms, thus causing contamination in soil foundation and deterioration of the conditions for development of indigenous organi ...

Subject:
biodegradation; chemical oxygen demand; containers; fermentation; glass; heat; heat treatment; hydrolysis; methanogens; nutrients; organic matter; polymers; sewage sludge; sewage treatment; temperature; volatile fatty acids; water treatment
Abstract:
... The factor which essentially affects sludge biodegradation rate is the degree of fluidization of insoluble organic polymers to the solved form, which is a precondition for availability of nutrients for microorganisms. The phases which substantially limit the rate of anaerobic decomposition include hydrolytic and methanogenic phase.Subjecting excess sludge to the process of initial disintegration s ...

Abstract:
... The aim of this study was to determine the effect of the soil tillage system on soil enzymatic activity. The performed investigations, employing two soil tillage systems: classical (ploughing) and simplified (no-tillage), were carried out on Luvisols and Arenosols differing typologically, with regard to their kind and species. The activity of the following five enzymes was determined in soil sampl ...

Subject:
groundwater; groundwater contamination; industry; oils; piezometers; pollutants; polycyclic aromatic hydrocarbons; temperature; wastes; water table
Abstract:
... Oil derivatives are commonly used and they play a key role in the economy. They are used in many industries. Such big amounts of oil derivatives products generate vast quantity of pollution. Those pollutants can get into the ground and water beyond any control during catastrophes or due to inadequately managed waste and storage. The aim of the paper was to determine the level of oil derivatives po ...

Abstract:
... Water and bottom sediment samples collected from a few fish-breeding ponds/reservoirs were subjected to tests. The aim of this paper was to determine the total content of aluminium and its fractions in the samples tested to estimate the potential risk to fish caused by the toxic forms of aluminium. The monomeric inorganic aluminium in waters was determined using the ion exchange and extraction-col ...

Abstract:
... Disinfectants are commonly used in households, hospitals, in drug manufacturing, in food processing. With the ever-increasing antibiotic-resistance of microorganisms, it is crucial to rationally apply disinfectants in suitable concentrations, with proper active substance, as not all substances affect various organisms in the same way. Among the microorganisms that are particularly difficult to kil ...
