The Hydrologic Simulation Program-FORTRAN (HSPF) model is widely used to develop management strategies for water resources and to evaluate the hydrologic effect of various management scenarios. The spatial resolution of the input data used to parameterize HSPF model may induce uncertainty in model...

Cerium oxide (CeO 2 ) nanoparticles (NPs) were used for the removal of cadmium (II), lead (II) and chromium (VI) ions in single aqueous solutions and in solutions with mixtures of the three metals. The adsorption studies were carried out at pH 5 and 7 using a systematic factorial experimental design...

An engine industry from Caxias do Sul city (RS, Brazil) has developed tests with biofuels to adapt their products to new fuel trends. Thus, this study aims to examine the components of their engines with potential degradation in the biodiesel usage. The most important aspects that were studied...

Granular activated carbon (GAC) was used in an Anammox process treating synthetic wastewater with the aim of evaluating its use as a growth nucleus to enhance granule formation. In an expanded granular-sludge-bed reactor, granules were formed demonstrating excellent retention characteristics with an...

In this study, Kandira stone, extensively used as a cladding material for building stone has been examined for the removal of an antibiotic Ciprofloxacin hydrochloride (CIP) from its aqueous solution. Batch experiments were performed to investigate the adsorption kinetics, equilibrium and...

Landfilling has been considered as the most common method for solid waste disposal in developing countries which is faced with several issues, such as gas emission. Methane as a greenhouse gas is the main landfill gas which could be applied as a fuel for electrical power plants. In this study, the...

The idea of wastewater application on soils, returned to Western Hemisphere during 1950-60. Modern living requires an increased per capita use of water for coverage of individual needs. Nowadays, two main principles related to water management seem to gain the attention of both the scientific...

An electrical resistivity survey was carried out in the premises of Chennai Metrowater Sewage treatment plants and Anna University to assess the suitability of underlying aquifer for reclaimed water recharge and also to understand groundwater conditions. The geo-electrical methods used in the survey...

Water quality of Edion and Omodo Rivers were assessed chemically from March to October, 2010. The abstracted water samples were also subjected to bacteriological examination. The Rivers were each sampled at upstream and downstream locations. Twenty (20) physico-chemical characteristics which...

Raw municipal landfill leachate is extremely polluted wastewater and it regards as one of the drawbacks of the sanitary landfill treatment method. If the untreated landfill leachate is discharged to the natural environment, a great problem for the environment can be created, particularly for the...
