One of the famous dyes is methylene blue (MB) which is a symbol of hazardous dyes. In this research, methylene blue was adsorbed using the blends of saffron petals with activated carbon. Five independent variables involving pH (2-13), contact time (5-270 min), saffron petals powder dosage (0.1-10 g/l), initial concentration of methylene blue solution (20-300 ppm) and activated carbon dosage (0....

To prepare an efficient supercapacitor, activated carbon from agave wastes was prepared and their electrochemical performance evaluated as a novel electrode for supercapacitor. The by two thermal pyrolysis processes under nitrogen atmosphere. first achieved at 500 °C until the charring of bagasse; in second step, char impregnated with different mass ratios KOH (1:2–1:4) thermally treated 800 or...

Biomass wastes are abundant around us. They renewable and inexpensive. Product manufacturing from resources has caught increasing interest recently. Activated carbon preparation biomass resources, including various trees, leaves, plant roots, fruit peels, grasses, is a good example. In this paper, an overview of activated production will be given. The first part on the processing technologies. ...

As a carbon neutral fuel, biodiesel is one option in future IMO scenarios for reducing intensity shipping sector, and at same time emission of pollutants. Some oily wastes, such as waste from olive oil production, might be used production second-generation biodiesel. The current study looks into the effect on characteristics gaseous pollutant emissions NOx CO slow-speed two-stroke marine diesel...

The influences of reactive and dielectric characteristics activators were investigated in the microwave-catalyzed conversion phenolic resin waste to activated carbon (AC). To compare with interactions microwaves treated samples, conventional electric heating for AC carbonization was also conducted parallel. porosity chemical features prepared examined, used remove ammonium from water through ad...

Work is focused to the study of unburned carbon in ash from coal (and wastes) combustion in 8 combustion tests at 3 fluidised-bed power station, at co-combustion of coal and wastes (also at fluidized bed) and at bench-scale unit simulating coal combustion in small domestic furnaces. The attention is paid to unburned carbon contents in bottom ashes and fly ashes at these 8 combustion tests and t...

the activated sludge process is the most used biological wastewater treatment method in the world. sludge bulking is one of the most common problems relateing to activated sludge wastewater treatment, and this fact causes poor settling in secondary sedimentation tank. sludge volume index(svi) and the zone settling velocity(zsv) are parameters to quantify the settleability of activated sludge . ...

the emerging contaminants are commonly derived from municipal, agricultural, and industrialwastewater sources and pathways. these compounds are polar and poorly biodegradable. the dynamicremoval of atenolol from aqueous solutions by activated carbon in fixed bed column systems was investigated. as far as we know, this is the first study reporting the decontamination by adsorption in fixed bed o...
