Molybdenum(VI) removal from aqueous solutions using bentonite and powdered cockle shell; Optimization by response surface methodology
Water and Wastewater Treatment
Removal of Mo(VI) from aqueous solutions by using bentonite and powdered cockle shell was conducted in this research. First, the effects of pH and initial Mo(VI) concentration on the Mo removal efficiency via shell and bentonite were studied. Results showed that Mo removal effectiveness increased as...
Competitive sorption of nickel, copper, lead and cadmium on okra leaves (Abelmoschus esculentus)
Water and Wastewater Treatment
In this study, potential of okra leaves for the removal of Ni(II), Cu(II), Pb(II) and Cd(II) from the mixed metal aqueous solution were evaluated. The data were analyzed by Freundlich, Langmuir, D-R, Flory-Huggins and Halsey adsorption models. Pseudo first order rate, Pseudo second order rate...
Effects of domestic and industrial effluent discharges into the lake and their impact on the drinking water in Pandravedu village, Tamil Nadu, India
Water Quality
Increasing demand for water from agriculture, industrial and domestic sectors, resulted in stress on the water resources both from quantity and quality perspectives. Due to urbanization many of the dyeing units have shifted from urban to nearby rural areas. Here safe disposal of untreated effluent...
Modelling the dispersion of benzene emissions from a proposed ethanol producing facility in Farewell-Oshawa of Toronto, Canada
Air Quality
The production and use of biofuels such as ethanol have been the target of intensive research. One source of ethanol is corn, which is abundant in many countries. In producing ethanol from corn, an assessment of the environmental impact of the process is needed. This study intends to provide insight...
Chromium biosorption from aqueous environments by mucilaginous seeds of Cydonia oblonga: Thermodynamic, equilibrium and kinetic studies
Water and Wastewater Treatment
Hexavalent chromium Cr(VI) is one of the most toxic heavy metals in aqueous solutions, hence it is highly imperative to treat the wastewater containing Cr(VI) before its discharge. At present work, the rate of biosorption was studied under a variety of conditions, including initial Cr(VI)...
Humic acid removal from water using a novel fabricated antifouling carbon nanotube bucky - paper membrane and effect of operating parameters
Water and Wastewater Treatment
In present work, a novel supported bucky paper (BP) membrane was fabricated and evaluated for humic acid (HA) removal from water. For better understanding the effect of operating variables, response surface methodology (RSM) was also applied. Three independent parameters namely TOC concentration (5...
Reproducibility of solid-state fermentation at bench-scale: the case of protease production
Solid Waste Management
Solid-state fermentation (SSF) process appears to be an efficient way to recover and valorise organic residues from industries and to generate other products of industrial significance, such as enzymes. As the reproducibility of SSF is one of the main drawbacks in the development of this process, a...
Biodecolourization and biotransformation of textile dyes remazol violet-5R and remazol brillant orange-3R by Bacillus sp. DT9 isolated from textile effluents
Water and Wastewater Treatment
The present study aims to evaluate RV-5R and RBO-3R decolourizing potential of Bacillus sp. DT9 isolated from textile effluent in Denizli (Turkey). In present study, maximum dye-decolourizing efficiency of the culture was achieved at 25 mg l -1 concentration of RV-5R and 500 mg l -1 concentration of...
Performance of different photocatalytic oxidation processes in petroleum wastewater treatment: A Comparative Study
Wastewater treatment
The present study was conducted to compare the performance of different solar photocatalytic processes (TiO 2 photocatalysis, photo-Fenton, photo-Fenton coupled with TiO 2 photocatalysis, and photo-Fenton coupled with TiO 2/ZnO photocatalysis) for the treatment of petroleum wastewater. The removal...
Effects of V2O5 and WO3 loadings on the catalytic performance of V2O5-WO3/TiO2 catalyst for SCR of NO with NH3
Air Quality
V 2O 5-WO 3/TiO 2 catalysts were fabricated by a simple impregnation method. Effects of V 2O 5 and WO 3 loadings on the catalytic performance of V 2O 5-WO 3/TiO 2 catalyst for selective catalytic reduction (SCR) of NO with NH 3 were investigated. Morphology and structure of the V 2O 5-WO 3/TiO 2...
