The survival of selected hygienically relevant bacterial species in activated carbon (AC) filters on a bench scale was investigated. The results revealed that after inoculation of the test strains the previously sterilized AC absorbed all bacteria (10(6) to 10(7)). After a period of 6 to 13 days without countable bacteria in the effluent, the numbers of Escherichia coli, Pseudomonas aeruginosa,...
Background and Objectives: Conventional methods of leachate treatment are inefficient due to high pollution loads and characteristics of the leachate. In recent years, an integrated method has been developed considerably. The aim of this research was to evaluate the effect of powdered activated carbon on the treatment of landfill leachate of Kermanshah City by a columnar aerobic sequencing batc...
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...
in this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using dried (bd) sargassum sp. (brown marine algae) and activated carbon (ac) prepared from it was examined. biomass, ph and the initial concentration of cr(vi), adsorption models and kinetic studies were investigated. the experiment was performed in a batch system and theeffect of solutio...
background and objectives: activated carbon is an adsorbent which is mostly employed in order to remove dye from aqueous solutions; however, commercial activated carbon is expensive and this is considered as an obstacle for its usage. therefore, the present study aimed to use waste paper as an inexpensive precursor to produce activated carbon. materials and methods: in the present study, koh wa...
this paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using persian mesquite grain. several techniques and methodologies such as, proximate analysis, n2 adsorption–desorption isotherms, scanning electron microscope (sem), fourier transform infrared spectroscopy(ft-ir), x-ray diffraction (xrd), x-ray photoe...
