  • Fundamentals of Catalytic Activated Carbons

    Untitled Document Summary: Catalysts in water treatment speed chemical reactions so equipment can be scaled down or contact times shortened. Because the speed of a reaction ...

  • 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 from lignocellulosic waste materials for water treatment: a review

    Activated Carbon (AC) adsorbents are commonly used to remove pollutants from water because of their excellent sorption ability. However, commercially available ACs are expensive. In developing countries where economy plays a very big role, it is better to find low-cost locally available precursors, which are renewable resources for the preparation of ACs. This review focuses on ACs prepared from ...

  • Boron removal by activated carbon and microfiltration for pre-treatment of seawater desalination

    This study aimed to enhance boron removal through powdered activated carbon adsorption (PAC) and application of a micro-filtration (MF) process as a pretreatment of a seawater reverse osmosis (SWRO) process. Batch and continuous experiments were conducted to investigate the effect of membrane filtration as well as PAC addition on boron removal in reconstituted seawater. In batch test, two kinds ...

  • Characterisation of activated carbon prepared from tamarind wood for wastewater treatment

    In this paper, an attempt has been made to produce activated carbon from tamarind wood, which is a forest waste, rich in lignocellulosic material. The characterisation of the activated carbon is done based on carbonisation time, temperature, pore volume and Brunauer, Emmett and Teller (BET) surface area under various operating conditions. The Scanning Electron Microscopy (SEM) analysis is also ...

  • 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 ...

  • Development of efficient characterization parameters for activated carbon used in drinking water treatment

    In many drinking water treatment facilities with an activated carbon (AC) purification step, polar and hydrophilic molecules are substances of concern. Many of the current test methods for AC do not really reflect AC's adsorption capacity for these substances. To develop a fast and economically reasonable parameter that characterizes AC's ability to remove these compounds, three ...

  • RO brine treatment and recovery by biological activated carbon and capacitive deionization process

    The generation of brine solutions from dense membrane (reverse osmosis, RO or nanofiltration, NF) water reclamation systems has been increasing worldwide, and the lack of cost effective disposal options is becoming a critical water resources management issue. In Singapore, NEWater is the product of a multiple barrier water reclamation process from secondary treated domestic effluent using ...

  • Assessment Of Single-Walled Carbon Nanotubes On Activated Sludge Wastewater Treatment Process

    This paper evaluated the impact of 95% purified single-walled carbon nanotubes (SWCNTs) on the activated sludge wastewater treatment process through a batch-scale study. We found that the SWCNTs adsorbed 22% of the soluble COD (sCOD, chemical oxygen demand). One-way ANOVA analysis revealed that only four experimental parameters, i.e., surface charge, sCOD, mixed liquor suspended solids (MLSS) and ...

  • In Situ Sediment Treatment Using Activated Carbon: A Demonstrated Sediment Cleanup Technology

    This paper reviews general approaches for applying activated carbon (AC) amendments as an in situ sediment treatment remedy. In situ sediment treatment involves targeted placement of amendments using installation options that fall under two general approaches: 1) direct application of a thin layer of amendments (which potentially incorporate weighting and/or binding materials) to surface ...

  • Superheated water pretreatment combined with CO2 activation/regeneration of the exhausted activated carbon used in the treatment of industrial wastewater

    This paper examines a novel method of regenerating saturated activated carbon after adsorption of complex phenolic, polycyclic aromatic hydrocarbons with low energy consumption by using superheated water pretreatment combined with CO2 activation. The effects of the temperature of the superheated water, liquid–solid ratio, soaking time, activation temperature, activation time, and CO2 ...

  • Investigation of removal of N–nitrosamines and their precursors in water treatments using activated carbon nanoparticles

    N–nitrosamines have been detected in various water types. A strategy for removal of this group of compounds should be taken to reduce the health risks for humans. In this study, a fast and sensitive LC–MS/MS method was developed for quantitative analysis of nine N–nitrosamines and four precursors in a single sample. The Method Detection Limits (MDLs) in natural water ranged from ...

  • Synergistic effect of biological activated carbon and enhanced coagulation in secondary wastewater effluent treatment

    The use of secondary wastewater effluent (SWWE) is an essential strategy for making better use of limited water resources. However, a wide range of organic compounds eventually renders them unsuitable for recycling. In water treatment processes, biologically activated carbon (BAC) is adopted after physicochemical treatment. However, the effectiveness of such combination for SWWE remains poorly ...

  • Toxicity reduction using powder activated Carbon

    Petroleum reserves, international politics and economic considerations are driving the domestic petrochemical industry toward heavy and sour crude slates. A consequence of the change is increased concerns related to the wastewater effluent toxicity. In 2005, a powdered activated carbon-activated sludge (PAC-AS) treatment process was installed at a petrochemical facility to reduce whole effluent ...

  • 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 ...
