Water and Wastewater Treatment
This study highlights the potential of steel slag, which is an industrial by-product of steel making industry as treatment media for metal-rich acid mine drainage (AMD). A series of batch adsorption studies has been done to demonstrate the effects of contact time, solution pH, initial concentration...
Efficient Removal of Methylene Blue by Adsorption Using Composite Based Ca/Al Layered Double Hydroxide-Biochar
Water and Wastewater Treatment
Composite based Ca/Al layered double hydroxide and biochar was prepared using mixing coprecipitation method at pH 10. Composite and the starting materials was characterized using X-ray, FTIR, BET, thermal, and SEM-EDX analyses. Furthermore, composite was used as adsorbent of methylene blue from...
Application of free and immobilized laccase for removal and detoxification of fluoroquinolones from aqueous solution
Water and Wastewater Treatment
Laccase from Trametes versicolor was immobilized by covalent bonds formation on CPC silica carriers. Elimination of two floroqinolone (FQ); enrofloxacine (ENR) and flumequine (FLU) using laccase in both free and immobilized form in the absence and presence of 1-hydroxybenzotriazole (HBT) and 4...
Correlational investigation of air pollutant emissions and fuel consumption of motor vehicle in various dynamic conditions
Air Quality
Air pollutant emissions and fuel consumption of vehicles equipped with internal combustion engines are highly susceptible to the conditions of engine operation. The purpose of this research was to investigate the correlation between the emissions of individual pollutants (carbon monoxide...
Catalytic removal of NO2 by Nickel _ platinum catalyst supported on multi-wall carbon nanotubes
Air Quality
In the present study, the NO2 removal efficiency at concentrations of 3000 to 5000ppm was evaluated by nickel and platinum bimetallic catalyst supported on multiwalled carbon nanotubes (Ni-Pt/MWCNT) along with water vapor at different space velocity and temperatures. Morphological and structural...
Air pollution as a result of the development of motorization
Air Quality
The problem of air pollution is one of the most important problems faced by the world in the context of large urban agglomerations. Numerous activities are being undertaken all over the world to both counteract existing pollution and prevent the emergence of another one. Manufacturing is one of the...
Greenhouse Gas Emissions From a Horizontal Subsurface Flow Constructed Wetland for Wastewater Treatment in Small Villages
Global Environmental Change
Constructed wetlands with a land-intensive, low energy and less operational requirement have been used as a sustainable green technology for treating wastewaters. But are constructed wetlands sustainable? The objectives of the present study are to evaluate one year monitored horizontal subsurface...
Assessment of hydrological response in Subarnarekha river basin under anticipated climate change scenarios
Water Resources Management
Two hydrological climate modelling techniques, general circulation model (GCM) and hypothetical climate change scenarios, were used to analyse the hydrological response to the anticipated climate change scenarios in the Subarnarekha river basin in Eastern India. Both models verified individually for...
Purification of waste water from cationic dye using SPGMA polymer: Isotherm and Kinetic study
Water and Wastewater Treatment
One of the known methods for dye removing from waste water is using sorbent material for fine removal of dye .The nano- cation exchanger Sulphonated poly glycidyl methacrylate (SPGMA polymer) was used as sorbent material for removing one of the common cationic dyes. SPGMA polymer was prepared and...
