River runoff forecasting is one of the most complex areas of research in hydrology because of the uncertainty of hydrological and meteorological parameters and scarcity of adequate records. Artificial neural networks (ANN) can be an efficient way of modelling stream flow processes as it is capable of controlling and modelling nonlinear and complex systems and does not require describing the complex nature of the hydrological processes. In this study, daily river flow is forecasted using two ANN ...

The present paper examined the photocatalytic degradation (PCD) of gas-phase trichloroethylene (TCE) over thin-film TiO2. A large-scale treatment of TCE was carried out using scale-up continuous flow photo-reactor that nine reactors were arranged in parallel and serial. The parallel or serial arrangement is a significant factor to determine the special arrangement of whole reactor module as well as to compact the multi-modules in a continuous flow reactor. The conversion of TCE according to the ...

In direct connection with the change in the solar energy conversion, the TR - Loss Coefficient (Tr??bungsfaktor) is...

Abstract Certain conventional and alternative carbon-based electrodes, i.e., glassy carbon electrode (GCE) and, commercial boron-doped diamond electrode (BDDE) were investigated and compared for the electrochemical determination and degradation of 2,4-dinitrophenol (2,4-DNP). The electrochemical behavior of electrodes in the presence of target pollutants was investigated using cyclic voltammetry (CV), chronoamperometry (CA), and multiple-pulsed amperometry (MPA). The duality of the electrode ...

Abstract Changing fuel consumption to a more ecological environmentally alternative is replacing fossil fuels with fuels generated from renewable resources. Ethanol, a renewable fuel, can be produced mainly from crops, lignocellulosic biomass and different other environmental wastes. Although ethanol has been produced mainly from crops, there is a great interest in using cheaper lignocellulosic materials as a feedstock for ethanol production. The aim of this paper is study of dilute acid hyd...

Abstract The cleanup of environmental pollution involves a variety of techniques, ranging from simple biological processes to advanced engineering technologies. Cleanup activities may also address a wide range of contaminants. Technologies to remediate contaminated soil fall into two principal clean-up approaches: in-situ (which is always done onsite), or ex-situ (which can be done on- or off-site). In-situ treatment deals with contamination without removing material from the ground, while ex...

Abstract:The implementation of the EU Bird and Habitat Directives by the ports and dredging industry caused severe project disruptions across North-West Europe in the past. 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 ...

Abstract:The aim of the present study is the optimization of biosorption conditions using a metal tolerant actinomycete (strain 723) for the removal of lead ions from waste water in batch and dynamic flow mode. The optimum conditions for lead biosorption by the strain were determined as initial pH 3.0, biomass amount 2.0 g L-1, and initial metal concentration 400 mg L-1 in the batch condition. The maximum lead biosorption performance was obtained with a 19 mm diameter column, a 1 mL min-1 flow r...

AbstractZinc is an important metal for humans and the environment. Its intensive application in industry has led to water and soilcontamination. A lot of microorganisms both unicellular and multicellular can be applied for removal of metals from theenvironment. The process of zinc adsorption by cyanobacteria Spirulina platensis biomass was investigated. The concentrationsof 0.34 mM and 3.4 mM of ZnSO4ˇ7H2O were used. The process of biosorption of zinc was studied during 1-hour experiment.To dete...

AbstractIn this study, a fuzzy-Markov-based interval stochastic dynamic (FM-ISDP) analysis method is developed for reservoir operationmanagement (ROM). In ROM, uncertainties could be represented as discrete intervals, fuzzy sets, and fuzzy-stochastic forms.FM-ISDP is framed on the integration of interval analysis, fuzzy vertex analysis, stochastic dynamic optimization approaches andthe fuzzy-Markov chain. The developed model is applied to a case of ROM within a multi-user, multi-uncertainty and ...

Abstract The present study deals with the removal of Cr (VI) from aqueous solution by polypyrrole (PPy). Response surface methodology (RSM) was applied for the design and analysis of experiments in the optimization of pH, temperature, initial concentration, contact time and adsorbent dose during the removal of the Cr (VI). The optimum adsorbent dose, temperature, initial concentration of Cr (VI), pH and contact time were found to be 0.8 g, 46.5 oC, 187.5 mg/L, 5.3 and 15.4 min respectively. ...

Abstract The objective of this study is to manufacture a geopolymer by replacing part of the metakaolinite by calcined oil-contaminated clay (OCC) and investigate its properties. The effects of the calcination temperature, the mix design of the alkali activator, and the degree of calcined OCC replacement on the properties of the geopolymer were studied. Evaluation of pozzolanic activity and compressive strength as well as micro structure observation by SEM and XRD were performed in this stud...

Availability of alternate fuels for cogeneration helps to limit the amount of bagasse as fuel at sugar plants and make them available for other uses such as paper manufacture or ethanol production. Due to the increased awareness on the adverse effects of carbon dioxide emission on the environment, power plant operators are compelled to reduce emissions of pollutants during cogeneration. Selection of low pollutant fuels, tapping of renewable energy and use of efficient operating policies can help...

According to Plackett-Burman-based statistical screening, seven of the eleven components of the medium had a significant effect on the metabolism of phenol degradation. Th...

This study aims to obtain high performance cement under friendly environmental conditions, through the optimization of clinkerization process. The influence exerted by mineralizers i.e. fluoride (NaF, KF) or oxide (CuO, TiO2) on the Portland clinker characteristics and derived cement properties is presented in this experimental study. The presence of these additions in low concentration (i.e. 0.5-0.8 wt. %) permits the reduction of the burning temperature (with 20oC up to 70oC) of raw mix and mo...

Fungal isolate Aspergilius niger V-8 (IITB) was isolated from the sludge of anaerobic digester of distillery wastewater treatment plant and was found to be an appropriate fungal isolate for the purposes of decolourization of anaerobically digested molasses spentwash (ADMS). The study aimed at optimization of the environmental parameters for achieving maximum decolourization of ADMS using isolated fungal species. Environmental parameters like initial pH, mixing, immobilization and surfactant a...

This paper highlights the utility of rice husk ash for the adsorption of Cr(VI) ions from aqueous solutions. Rice husk ash (RHA) is produced when rice husk is burnt for various purposes. Application of Treated Rice Husk Ash (TRHA) as an adsorbent for the removal of Cr(VI) from aqueous solutions has been investigated. For this purpose, RHA was thermally treated. RHA and treated RHA (TRHA) were characterized by XRD, SEM and FTIR to investigate the effect of treatment on the nature and surface char...

This study evaluated the performances of adsorption and Fenton oxidation for the removal of multilan red (MLR) and multi-active blue (MActB) dyes from aqueous solution. Zeolite, the adsorbent used in the study was modified using two surfactants: hexadecyltrimethylammonium bromide (HDTMA-Br) and cetyltrimethylammonium bromide (CTAB). The modified zeolite characterized using FTIR, SEM and XRD analysis. The modification studies revealed that HDTMA-modified zeolite exhibited better performance than ...

Köyceğiz-Dalyan Lagoon is situated in the southwestern region of Turkey. The area between the Köyceğiz Lake and the sea is covered with four small lakes and numerous canals. The Dalyan Channel network connects lake to the Mediterranean Sea is one of the most important reproduction areas for Mediterranean Sea turtles. The objectives of the present study are to evaluate the influence of channel traffic and Köyceğiz Lake on the water quality of Dalyan Channel by evalua...
