Effect of modification with FeCl3 and MgCl2 on adsorption characteristics of woody biochar
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Due to high specific surface area, well-developed porous structure and surface functionality biochar has a potential for being used as low-cost adsorbent for adsorption of organic and inorganic contaminants from aqueous ... -
Experimental study of droplet biofilter packed with green sphagnum
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Air cleaning from VOC (volatile organic compunds) group of contaminants could be done by using different types of methods: adsoption, absorption, chemical or thermal oxidation. However, the most promising method is bio ... -
Heavy metals leaching of MSWI bottom ash: effect of short-term natural weathering
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Municipal solid wastes incineration (MSWI) is an important part of the waste management systems in many European countries. Incineration process generates two main by roducts: fly ash (FA) and bottom ash (BA). Bottom ash ... -
Heavy metals uptake by trees near a waste incinerator
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Incinerators produce energy burning virtually everything including waste, but emit pollutants such as heavy metals and carbon monoxide (CO). These substances can be uptaken by trees through their roots, leaves or stems. ... -
Integrated evaluation of road transport pollution impact on the urban air
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)With the number of vehicles increasing, the analysis of urban air pollution becomes expedient. This article deals with the integrated evaluation of road transport realised pollutant impact on the urban air. During research, ... -
Investigation and modeling of manganese concentration in the gravel roadside
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Road transport is one of the biggest soil polluter. There are a lot of investigations of soil pollution near highways, but soil pollution near gravel roadsides needs more experimental research. In this experimental study ... -
Mathematical modelling for copper and lead adsorption on coffee grounds
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Research studies on the adsorption kinetics are conducted in order to determine the absorption time of heavy metals on coffee grounds from liquid. The models of adsorption kinetics and adsorption diffusion are based on ... -
Modelling of piezoelectric transducers for environmental monitoring
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)World Health Organization (WHO) defined health as being “a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity”. Physical factors (noise, vibration, electromagnetic ... -
Nitrogen compunds in the surface water identifying concentrations and sources
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)The main objective of the surface water monitoring – periodically to conduct water quality testing, to find out the possible sources of pollution in time and to warn population. Water samples for analysis of surface water ... -
Research and evaluation of the aromatic hydrocarbons in the polluted wooden railway sleepers
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Wooden railway sleepers are impregnated with the chemicals that prevent the disassembling of the wood splitter. Such chemical wood impregnator as creosote or shale oil have been widely used to prolong the lifetime of wooden ... -
Research on odours emitted from non-hazardous waste landfill using dynamic olfactometry
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)The article analyses the existing research on odour emissions from the passive odour source – municipal landfill for non azardous waste. The current research has been carried out in the Vilnius county, at the Kazokiškės ... -
Researches of aggressive gas flow cleaning from wood ash particulate matter in the multi-channel cyclone
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)The studies examined the gas flow aerodynamic parameters and treatment efficiency from the wood ash particulate matter, also an adhesion dependencies in multi-channel cyclone using aggressive gas flow – temperature up to ... -
Soil surface pollution with heavy metals caused by coal-fired boilers
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)One of the goals for environmental experts is to help avoid, prevent or reduce harmful effects on human health and the environment as a whole. The idea is that the public and the polluting companies would be informed of ... -
Theoretical end experimental evaluation of perforations effect on sound insulation
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)To design a sound-absorbing panel, it is important to identify factors that affect the maximum sound absorption of low, middle and high frequency sounds. Perforation effect is very important for the noise-reducing and ... -
Theoretical evaluation of heavy metals migration and sorption in soil
(10th International Conference “Environmental Engineering” (ICEE-2017), 2017)Heavy metals are one of the group of toxic pollutants in the soil. Over the past years, many researches have been conducted on the migration of heavy metals in soils and various models were developed in order to study the ...
