Abstract:
Albendazole is an anthelmintic drug with antiangiogenic properties, which means that inhibits the development of new blood vessels. This causes a serious risk for the growth of fetus during pregnancy as a result. Heterogeneous photocatalysis has been proposed as an alternative for removal of this contaminant. In this study, a solar compound parabolic collector (CPC) photocatalytic reactor was modeled and simulated in order to describe the total organic carbon (TOC) degradation of commercial albendazole.

Abstract:
An experiment to study and to build a mathematical model to reproduce the behavior of nitrogen in a residential wastewater treatment process was performed. A pilot unit receiving grey and black water was used. The pilot consisted in a septic tank followed by a fixed-film, partly aerated bioreactor with effluent recirculation operated under two different scenarios: normal operating conditions and increased influent flow. Modeling was performed with the GPS-X™ software. Following a sensitivity analysis, the model was calibrated by comparing results from the pilot experiment and those of the simu

Abstract:
Abstract Decentralized wastewater systems treat, dispose and reuse the wastewater in the vicinity of source, reducing the sewage transportation cost to minimal. As an alternative to centralized systems it can function as a satellite system or an individual wastewater treatment unit. Design an onsite facility applies the same sizing procedure compared the conventional large scale systems, whereas the input flow data and its variability, the model parameters could differ. In this study a small size treatment unit was designed by biokinetic modeling, where the model parameters were estimated usin

Abstract:
The impact any power plant has upon the environment must be minimized as much as&#x0D;possible. Due to its high efficiency, low emission levels and low cooling requirements,&#x0D;combined cycle plants are considered to be environmentally friendly. This study evaluates&#x0D;the effect of operational conditions on pollutants (CO, CO2, SOx, NOx) emissions levels,&#x0D;waste-heat and wastewater of a combined-cycle natural gas and steam power plant. The&#x0D;HYSYS process simulation was used for modelling and simulation. The study clearly&#x0D;shows that the absolute quantity of pollutants emitted

Abstract:
At least 70% of WWTP of small capacity in Russia include biofilters, that's why development of new technologies for treatment and methods of reconstruction are the points of great interest This abstract describes the methods and techniques of biofilters reconstruction to achieve desired water quality. The presence of biogenic compounds (NH4, PO4) in the water body are one of the causes of eutrophication. The article considers the methodology of modeling processes of wastewater treatment in the biofilters: The results of sanitary - chemical researches and researches of the formed biomass are gi
