The present study associates groundwater nitrate pollution with agricultural activity in the Upper-Cheliff wich is known for intensive farming practices. The indicatory kriging method is used in order to elaborate a map of the spatial probability distribution of nitrate concentration that exceeds a...

In this paper, one partial nitritation system with biological selector (PNBS) was first evaluated in treating high-strength ammonia containing wastewater. Nitrite production rate (NPR) of 8.25 kg N m -3 d -1 was achieved with influent NH4-N concentration 2000 mg l -1 and HRT 3.2 h, which is, to our...

ISC-Aermod view dispersion model has been used to study the ground level concentration of hydrocarbon (HC). The purpose was to predict the air quality effects from off-grid diesel power generators operated by a textile factory in Lagos, Nigeria on its host airshed. Emissions from 22 point sources in...

Current study was carried out to investigate the heavy metals removal from landfill leachate and urban wastewater by powdered activated carbon and powdered zeolite augmented SBR technique. The research was carried out in six 2000 mL breakers (working size was 1200 ml). The reactors were parted into...

The coagulation potential of alginate extracted from marine brown algae, Sargassum sp. for the removal of Direct Blue 2 dye from aqueous solution was studied. Extracted alginate was characterised by Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopy (SEM) techniques...

The present study investigates the ability of formaldehyde treated Simarouba glauca seed shell powder for removal of methylene blue (MB) from aqueous solutions. Batch adsorption studies were carried out under various experimental conditions such as agitation time, dye concentration, adsorbent dose...

The aim of this search was to identify the 101 top cited articles in the field of oil spill remediation. A search was conducted based on a database of the Web of Science included the journal citation reports from 1980 to 2013. The number of citations of the first 101 top cited articles is from 24 to...

The effect of pre-ozonation on the formation of four aldehydes (i.e. formaldehyde, acetaldehyde, glyoxal, methyl glyoxal) and two ketones (i.e. pyruvic acid and glioxalic acid) at the Beheshti water treatment plant in Hamadan, Iran were studied. Water samples were taken from the treatment plant at...

In this study, the photocatalytic degradation of two biologically treated textile finishing wastewater was investigated using powdered TiO 2 and ZnO catalysts with UV-A lamp irradiation. Photodegradation and photodecolorization of the samples real textile industrial wastewater is observed directly...

In vitro tolerance of soil borne phytopathogenic fungus i.e. Alternaria alternata in terms of growth, physiology and metal uptake capacity against different doses of copper [Cu(II)] metal was assessed. In preliminary growth experiments, nitrate, chloride and sulphate of Cu(II) were amended in seven...
