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...

Ammonia (NH3) and hydrogen sulfide (H2S), as the main odorous substances in waste gas from livestock farm, have attracted more attentions rescently since their adverse effects. To remove NH3 and H2S efficiently, high-pressure hydrothermal modification (HPHM), metal salt solution impregnation...

In this study, an investigation was carried out in order to determine the potential of ordered mesoporous carbon including high ratio sucrose in its composition as a CO2 adsorbent. Structural characterizations of silica and carbon material were determined by using a scanning electron microscope (SEM...

This study was conducted to investigate the effect of different types of organic wastes (grass and newspaper wastes, cow dung and their combination) on physicochemical properties during vermicomposting using Eisenia fetida. Three set-ups were conducted in which three experiments were for composting...

Wastewater from textile industry is considered one of the major environmental challenges due to the large volume of highly colored, polluted and toxic effluent. This study investigated the treatability of real textile wastewater by pilot-scale anoxic-aerobic Membrane Bioreactor (MBR) system without...

Synthetic dyes have a hurtful effect on human health and the environment. In this work, activated carbon was produced from date stones for use in elimination of methylene blue charged in aqueous solutions. Before that, the adsorbent was characterized by BET method, SEM, X-ray and TGA. The results of...

Microbial community was determined in a pilot-scale two-stage step-feed biological nutrient removal system treating municipal wastewater with 10 m3 d-1 capacity. Grit chamber effluent at Istanbul Ataköy Biological Wastewater Treatment Plant was used as influent wastewater. In the pilot plant, the...

Population growth, urbanization and anthropogenic activities are becoming a serious problem for water resources in Turkey, which necessitates their monitoring and maintenance of water quality. In this study, water quality was implemented in the Porsuk Stream in Inner Anatolia, Turkey. Water samples...

In this study activated carbon is produced from areca plant leaves, an agricultural waste material. The physical and chemical structural characterisation of the prepared carbon was carried out by FTIR, TGA and XRD analysis. FTIR study showed the presence of several functional groups, such as C=O, C...

Diplocyclos Palmatus biomass activated carbon (DPAC) was used in this work to remove lead (II) ion from the synthetic wastewater. The DPAC was characterized for structural, surface morphology by SEM, functional group was analyzed by FT-IR and XRD analysis. Removal of Pb2+ was studied by batch method...

The aim of this study was to evaluate the mercury removal from aqueous solutions by using L-Cysteine functionalized Multi-walled Carbon Nanotubes. The effect of pH, adsorbent dose, contact time and mercury concentration in removal efficiency was evaluated. Multi -walled carbon nanotubes were...

In recent years, n-hexadecane, a component of diesel petroleum hydrocarbons, is frequently detected as the contaminant in many soils and water resources. The main aims of this study were focused on the feasibility of using the biodegradation for the removal of n-hexadecane from the soil-slurry...
