  • Removing mercury with activated carbon

    Granular Activated carbon is effective at physically adsorbing trace components from gas streams due to its high population of micropores; however, the capacity is low. By impregnating the granular activated carbon with a compound that will chemically react with the mercury, capacity can be enhanced. It is imperative that not only must the mercury be removed to non-detectable levels but that it ...

  • The Many Uses of Activated Carbon

    Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 ...

  • Activated Carbons and Manufactured Gas Plants

    The purpose of this paper is to discuss the pros and cons related to each of these factors when using one of three accepted options in conjunction with the "hog and haul" method of remediating a site. The options are the use of (1) minimal controls, (2) extensive onsite monitoring and (3) a fabric structure with limited air testing. As we are all aware, the government continues to react to ...

  • Top 3 Uses of Activated Carbon

    Activated carbon is an effective purifier. It is used to remove organic pollutants from different gaseous, liquid and solid substances. By removing the undesirable organic compounds, activated carbon can successfully remove the odour and taste of these compounds from a wide range of things.  Unlike other purification agents that react with organic compounds and change their nature, activated ...

  • Overheating Damage at Activated Carbon Filter

    At one of the DMT’s plants recently a safety incident occurred. An Activated Carbon Filter overheated due to an incorrect mode of operation, causing damage to the installation. This led to a significant financial loss including business interruption impacts. To raise awareness for correct operation of Activated Carbon Filters, DMT publishes this S.H.E. bulletin to prevent this from ...

  • Activated Carbon: What it is, how it works

    Untitled Document Summary: In the last decade public awareness and concern over the quality of drinking water has resulted in more and more consumers turning to point-of-use ...

  • Membrane fouling mitigation by activated carbon addition in activated sludge filtration

    Activated carbon (AC) was added into the activated sludge to alleviate membrane fouling during sludge microfiltration. The fouling mitigation profiles were evaluated at different AC sizes and doses by a single-fibre microfiltration system. It was found that the granular AC added in the sludge suspension can absorb the organic substances in the sludge in a certain level, including biopolymer ...

  • Properties of activated carbon prepared from rice husk with chemical activation

    The present work involves an investigation of the possible use of activated carbon developed from rice husk by chemical activation with zinc chloride (ZnCl2) and phosphoric acid (H3PO4) under different activation conditions for the removal of phenol from artificial wastewater. The physical and ...

  • Physicochemical effect of activation temperature on the sorption properties of pine shell activated carbon

    Activated carbons produced from a variety of raw materials are normally selective towards a narrow range of pollutants present in wastewater. This study focuses on shifting the selectivity of activated carbon from inorganic to organic pollutants using activation temperature as a variable. The material produced from carbonization of pine shells substrate was activated at 250°C and 850°C. Both ...

  • Optimisation of activated carbon production from date pits

    This study investigates the optimal process conditions for activated carbon production from local date palm pits using response surface methodology (RSM). Box Behnken statistical technique was used to design the production process in order to determine the influence of activation temperature (300°C to 700°C), % H3PO4 (30% to 70%) and ...

  • Oxidized fulvic acid adsorption on activated carbon

    This study evaluates and compares the parameters of equilibrium adsorption from aqueous solutions of river fulvic acids (FA) and peat fulvic acids. Compared to peat FA, the river FA had lower biodegradable dissolved organic carbon (BDOC). We observed a tendency for correlation between change of Gibbs free energy of adsorption and BDOC value. A chlorination dose of 1.4 mg L−1 did not ...

  • Promoted ozonation for the decomposition of 1,4-dioxane by activated carbon

    Worldwide attention has been attracted to 1,4-dioxane because of its probable human carcinogenicity and frequent occurrence in surface waters and wastewaters. Thus, many countries and organizations have set limits for the amount of this material in drinking water and wastewater effluent. However, the removal of 1,4-dioxane during traditional treatment processes, even ozonation (pH < 7), has ...

  • Cadmium ion adsorption by amine-modified activated carbon

    Cadmium (Cd) is one of the most toxic metals found in water and sediments. In the effort to develop an effective adsorbent for aqueous Cd removal, activated carbon (AC) was modified with an amino-terminated organosilicon (3-aminopropyltrimethoxysilane, APS). Response surface methodology was used to optimize selected operational parameters of adsorption of aqueous Cd by considering a central ...
