Porous asphalt pavement (PAP) with a high drainage capacity was modified powdered activated carbon (PAC) addition to produce permeable reactive (PRP), which may exhibit the potential reduce environmental non-point source (NPS) pollution. The experimental design mixtures used and test PRP incorporated PAC (named PRP-PACs) were conducted as follows: first, PACs initially tested determine their fe...
Selecting a single powdered activated carbon against multiple threats: taste & odour and benzene
MIB and geosmin removal performance by 11 supplier-recommended powdered activated carbons varied factor 3 to 4. Well performing also effectively removed benzene traces.
Background and Aim: Heavy metals have been recognized as very poisonous elements and their discharge into water sources can cause damaging effects on human and environmental health. The present study aimed at producing activated carbon from scrap tires and using it in removing Pb+2 from synthetic aqueous solutions. Materials and Methods: In this experimental study, activated carbon p...
In this laboratory scale study, impregnated almond shell activated carbon was used as adsorbent to investigate its feasibility for nitrate adsorption from aqueous medium. The effects of activated carbon dosage and contact time have been examined in batch experiments. Experimental data show that impregnated activated carbons by Fe0, Fe2 (SO4)3, and FeSO4 were more effective than virgin almond ac...
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...
abstract aims: even low concentrations of phenol in industrial waste can cause many difficulties for the aquatic environment. so removal of this organic matter is an important issue. the adsorption process, is one of the most effective methods for isolation and purification of phenols. the aim of this study was to introduce wood haloxylon as a natural and new absorbent to remove phenol from aqu...
in the paper we developed a new method to determine the absolute amount of adsorption. this method relies on the excess adsorption isotherm and the density profile in the pore of one material. to compute the density profile and decrease complex calculation of obtaining the absolute amount of adsorption we introduced simplified local-density (sld) model. a few of appropriate parameters were acqu...
applying nanoporous materials is an appropriate method for improving chemical quality of the water due to high surface area, internal porous structure (porosity), high absorption capability of harmful gases and liquids, and capability of reactivating the surface. therefore, actions were carried out in order to investigate the effect of activated carbon and zeolite on reducing the total dissolve...
In this study, the reduction of emerging organic contaminant atrazine in water, was investigated by adsorption, oxidation and a combination both technologies. Adsorption tests were performed using method ASTM D3860-98 with two types activated carbon: powdered carbon granular carbon. For tests, advanced ozone technology used. Finally, combined firstly adsorption treatment applied followed then o...
Special attention was paid in this work to the role of surface chemistry in the adsorption of phenol and salicylic acid onto activated carbons. To this end, two commercial activated carbons (granular and powdered) were oxidised using ammonium peroxodisulphate [(NH4)2S2O8] and nitric acid in different concentrations. The structural and chemical properties of the oxidised adsorbents were characte...
