Comparative study on physical and mechanical properties of high slump and zero lump high volume fly ash concrete (HVFAC)
General
An experimental investigation was carried out to compare the compressive strength of zero slump and high slump concrete with high volume fly ash. 40% to 70% replacements of OPC (by weight) with class F fly ash have been incorporated. Superplasticizer was added at 1% of binder (cement + fly ash) to...
Integrated strategy to enhance biogas production from mango peel waste
General
The present study has successfully explored the use of pomegranate seed de-oiled cake as a major additive and micronutrients solution as a minor additive to enhance production of biogas and enrich its methane content, using mango peel as the initial substrate. While micronutrients solution has...
Feasibility study of biohydrogen production from pressmud by UASB process and assessment of operating parameters
General
Anaerobic digestion of pressmud diluted with water for biohydrogen production was performed in continuous fed UASB bio reactor for 120 days. Experiment was conducted at a dilution ratio of 1:7.5, by maintaining constant HRT of 30 hrs and the volume of biohydrogen evolved daily was monitored. Various...
Investigation of the effect of operational parameters and SnO2-coupling on the photocatalytic activity of TiO2
General
The effect of different operational parameters in UV/TiO2 process, such as initial dye concentration (20-50 mg l-1), light intensity (8-45 W m-2), pH (2.83-10.22), hydrogen peroxide concentration (100-500 mg l-1), temperature (21-45 ˚C) and photocatalyst concentration (150-900 mg l-1) were...
Equilibrium, thermodynamic and kinetic studies to study the sorption of rhodamine-b by moroccan clay
General
This study aimed to evaluate the sorption capability of an inexpensive and easily available Moroccan clay, called locally Ghassoul, to remove Rhodamine B (Rh-B) from aqueous solution. Experimental results showed that the equilibrium sorption data fitted well with the Langmuir isotherm and the...
Removal of cationic dye (basic red 18) from aqueous solution using natural turkish clay
General
In this study, the removal of a cationic dye, basic red 18, used in the textile industry with montmorillonite was investigated as a function of initial dye concentration, pH, agitation speed, adsorbent dosage, ionic strength, and temperature. Adsorption process was attained to the equilibrium within...
Comparison of naturally prepared coagulants for removal of COD and color from textile wastewater
General
The wastewater generated by the textile industry is rated as the most polluting among all industrial sectors considering both volumes discharged and effluent composition. Present investigation intended for COD and color removal from textile wastewater using naturally prepared coagulants i.e. Surjana...
Co-composting of meat packing wastewater sludge and organic fraction of municipal solid waste
General
The use of organic manures as amendments to improve soil organic matter level and long term soil fertility and productivity is gaining importance. The disposal of the great quantity of organic wastes produced by the municipal, agricultural and agroindustrial activities, is causing energetic...
Effect of various parameters in removing Cr and Ni from model wastewater by using electrocoagulation
General
The performance of a laboratory scale electrocoagulation system for the removal of Cr and Ni from model wastewater was studied systematically using iron and aluminum electrodes with an effective surface area of 13.8 cm2 and a distance of 4 cm. The influence of several parameters, such as initial...
Comparison of particle emissions from enclosed parking garages and streets
Air Quality
The aim of this study was to compare particulate matter (PM) pollutants performed at three different enclosed parking garages (A, B and C) and two streets (1 and 2) in Belgium. Particle mass concentrations, number concentrations and their size distributions were measured in real time using an...
DBP formation and speciation in a central anatolian dam water depending on pH, TOC level, fraction and chlorine dose
General
The effects of pH, NOM concentration, fractions and the chlorine dose on the formation and speciation of THMs and HAAs were determined in Altinapa Dam water (Konya/Turkey). Water sample was isolated and chlorinated at different TOC levels and pH’s. The isolate was fractioned; THM and HAA species...
A study of the role of micrometeorological conditions on uptake of 3,4-dichloroaniline in maize
General
3,4-dichloroaniline (3,4-DCA) is a hardly biodegradable and hydrolysable compound, characterized as a persistent pollutant for water, soil and sediment and highly toxic for living organisms. In this work, the impact of different micrometeorological conditions on uptake of 3,4-DCA was investigated in...
