Effect of flow and module configuration on SO2 absorption by using membrane contactors
Air Quality
Sulfur dioxide (SO2) emissions lead to negative environmental impacts and it is considered as an indicator for the larger group of gaseous sulfur oxides (SOx) in the air. In this paper, the dimethylamine (DMA) solution was used as the absorbent in a α-Al2O3 hollow fiber membrane contactor that is...
Assessment of residential exposure to Volatile Organic Compounds (VOCs) and Carbon Dioxide (CO2)
Air Quality
There is increasing concern about indoor air pollution worldwide due to its adverse health effects. One of the predominant indoor air pollutant groups is assumed to be volatile organic compounds (VOCs), including a variety of hydrocarbons with different functional groups. Among VOCs, some species...
Preliminary investigation on ultrasound frequency determination in TNT, RDX and HMX degradation
Water and Wastewater Treatment
The wastewater of the munitions industry varies in terms of the recalcitrant compounds depending on the products and the manufacturing process. The most commonly encountered energetic nitro-aromatic compounds in ammunition wastewater are trinitrotoluene (TNT), nitro-heterocyclic hexahydro...
Anaerobic two stage degradation pattern of fermentable components of municipal solid waste
Solid Waste Management
With increased contribution of household and kitchen wastes in overall MSW and its preferred conversion by biomethanation there is a need to study decomposition rates and kinetics, ‘leachate potential’ and related issues– especially to promote decentralized treatment. Anaerobic digestion...
Methylene Blue removal from aqueous solutions by activated carbon prepared from N. microphyllum (AC-NM): RSM analysis, isotherms and kinetic studies
Water and Wastewater Treatment
This study was conducted to remove Methylene Blue (MB) from aqueous solution using activated carbon prepared from N. microphyllum (AC-NM) as a new, cheap, and non-toxic. Design of experiments based on Response Surface Methodology (RSM) conducted to investigate the effect of variables namely; initial...
Potential causes of high performance of pure-oxygen aerobic granules in SBR under high organic loading condition
Water and Wastewater Treatment
Aerobic granules were cultivated using pure oxygen aeration (POAG) in SBR for wastewater treatment under high organic loading condition (HOLC) to reveal its performance and potential causes. Compared to conventional granules and activated sludge, mature POAG with more compact and dense structure...
Evaluvation of Paper recycling Wastewater Treatment Accompanied by power generation using Microbial Fuel Cell
Wastewater treatment
This study investigates the feasibility of using cathode catalyst (Iron phthalocyanine (FePc) combined multi walled carbon nano tubes (MWCNT) and compares the oxygen reduction rate under different conductivity of catholite solution (50 mM, 100mM) in double chamber Microbial Fuel Cell. Microbial fuel...
Identifying the Quiet Areas of a Small Urban Setting: The Case of Mytilene
General
The aim of this study is to achieve a greater insight regarding quiet areas in agglomerations and contribute to their identification. The small urban setting of Mytilene located in the island of Lesvos (North Aegean, Greece), was the case study of this research. Based on citizen contribution, a...
Effect of aerosols on different regime of clouds and their precipitation over Tehran city
Air Quality
In this study we investigate the impact of aerosols on different cloud regimes and amount of their precipitation over Tehran for the period of 2003-2014, utilizing data from Moderate-Resolution Imaging Spectroradiometer (MODIS), Tropical Rainfall Measuring Mission (TRMM) and surface data from local...
Evaluation of the potential genotoxic activity in seawater of Asin Bay, Gulf of Gulluk, Mugla, Aegean coast of Turkey
Hazardous Substances and Risk Analysis
This research examined the genotoxic activity in the seawater of Asin Bay (Gulf of Gulluk) located in Mugla, Turkey, Aegean coast of Turkey. Genotoxic activities of 66 raw samples, taken from 17 different stations in the spring and summer seasons of the year 2013, were determined by using in vitro...
