AbstractDuring the transition to a market economy, many countries with a planned economy in Central and Eastern Europe face similar challenges when the established socio-economic systems and infrastructures deemed inefficient in a market economy. Also new issues are being raised by the trends of globalization and the vision of sustainable development. In the energy sector the challenges raised by the Kyoto Protocol and its implementation mechanisms are especially interesting, because they are in...

AbstractThis paper reviews some practical aspects of the application of algal biomass for the biosorption of heavy metals from wastewater. The ability of different algal species to remove metals varies with algal group and morphology, with the speciation of specific metals and their competition with others in wastewater, and with environmental or process factors. The scattered literature on the uptake of heavy metals by both living and dead algal biomass - both macroalgae and immobilized microal...

Modifying the fly ash surface can be a solution for reaching both goals. The use of FA for heavy metals removal, from wastewaters resulted in the dye finishing industry, faces a supplementary p...

The prevalence of negative experience triggered a new approach, which aims to integrate site-specific ecosystem characteristics and project objectives during the development of the initial project design. This approach is termed "Building with Nature". The authorities and practitioners hope that the new approach will improve ...

Soil hydraulic characteristics are variable, being influenced by climate changes. Research conducted until now in this area has been based on field soil sampling; their laboratory analysis using experimental techniques; and the use of models and programs for data processing and interpretation. The present research is based on the idea of incorporating smart sensors on site, each one having its own network address, accessible for any location. They can be programmed to send an alarm signal when t...

This paper presents a study on the integration of two advanced treatment processes for the removal of priority organic processes from wastewaters: catalytic oxidation (Fenton homogenous process) followed by ultrafiltration. The aim of this study was to assess the removal efficiency for 4-chlorophenol (used as model pollutant), as well as the decrease in effluent toxicity in various processes conditions. The experiments have mainly focused on studying the effect of the oxidant dose of the catalyt...

Chromium and cadmium are heavy metals that occur naturally in the environment and especially in soils. Their toxic effect is more pronounced at high concentrations and it depends on the oxidation states. While Cr (III) is considered an essential trace element for the metabolism of living organisms, Cr (VI) has a higher mobility and is easily soluble in soils and can be leached into surface water or groundwater, and taken up by plants. That leads to a toxic and carcinogenic effect to humans via i...

Three methods have been employed for this purpose. The first method involved the use of an autoclave, where synthesis has been performed at a temperature of 120 0C and a treatment time of 4 to 8 hours. Within the second method, the modification of the ash at a temperature of 600 0C by fusion was carried-out. In this method, a mixture of as...

AbstractMunicipal wastewater, characterized by temperatures of 14-22°C in the inflow of Wastewater Treatment Plants and above 35-40°C in domestic outflows, represents a relevant thermal energy source. A feasibility study of the implementation of heatrecovery from a specific sewer system should take into account several aspects: potential heat capacity (depending on wastewatertemperature and flow rate in the considered area and climate conditions, and on the sewer characteristics), users that cou...

At the same time Se can be toxic leaving a narrow optimal range for optimal intake. Both excess and deficit are known to cause a wide range of clinical manifestations. Even though a large body of evidence provides vast information about Se, the exact molecular mechanisms of i...

Among the organic pollutants, the chlorinated phenols represent an important class of compounds having a stable world market of ca. 100 kt per year. Due to their aryl structure and presence of the chlorine atom, chlorinated phenols are exceptionally recalcitrant toward chemical reactions aimed at their reduction. Adsorption from liquid phase has received special interest due to its flexibility and simplicity in operation. Especially adsorption using activated carbon (AC) has been recognized by t...
