  • 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 ...

  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • 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 ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Carbon footprint of food-related activities in Finnish households

    Consumers play an important role in the food chain environmental system. However, there seem to be only few studies that have focused on food-related environmental impacts of consumer activities. This paper identifies the primary consumer activities that affect carbon footprints and their relative importance, and consumer choice in household food-related transportation, preservation and ...

  • Activated Carbon Applications Excel at PCB Removal

    TIGG’s GAC adsorption equipment is used to remove PCBs from groundwater. For more than 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials including, caulking, cutting oils, inks, paints and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban of ...

  • TIGG Activated Carbon Box Adsorbers Contain VOCs at MGP Site

    Tasked with the excavation, removal and solidification of soil containing coal-tar by-products generated by a former manufactured gas plant in New York, an experienced environmental remediation firm decided to use a method that proved successful in previous projects. TIGG activated carbon box adsorbers were used to contain VOCs at the former MGP site undergoing environmental remediation. By ...

  • Positioning activated carbon amendment technologies in a novel framework for sediment management

    Contaminated sediments can pose serious threats to human health and the environment by acting as a source of toxic chemicals. The amendment of contaminated sediments with strong sorbents like activated carbon (AC) is a rapidly developing strategy to manage contaminated sediments. To date, a great deal of attention has been paid to the technical and ecological features and implications of ...

  • Experimental study and modelling of zinc adsorption by granular activated carbon and natural zeolite

    The metal removal capability of Granular Activated Carbon (GAC) and natural zeolite is evaluated in this study using zinc as a model adsorbate. The equilibrium and kinetic characteristics of zinc adsorption on GAC and natural zeolite were studied in batch stirred tank experiments. The adsorption data for both systems were fitted by Langmuir, Freundlich, Langmuir-Freundlich, and Redlich-Peterson ...

  • 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 ...

  • 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 ...

  • Pilot-scale study of powdered activated carbon recirculation for micropollutant removal

    Adsorption onto powdered activated carbon (PAC) is a promising technique for the removal of organic micropollutants (OMPs) from treated wastewater. To enhance the adsorption efficiency, PAC is recycled back into the adsorption stage. This technique was examined in pilot scale in comparison to a reference without recirculation. Coagulation with Fe3+ was carried out simultaneously to adsorption. ...

  • Influence of solute dissociation constants on the optimum adsorption of weak electrolytes on activated carbons

    The pH of solutions has dramatic effects on the adsorption capacity of activated carbons from solutions, while the adsorption curves for weak electrolytes acquired as a function of pH show maxima at some intermediate pH. This intermediate pH is usually near the pKa of the electrolyte. Some apparent controversy inherent in these statements has, however, motivated experimental and analytical ...

  • Activated carbon for the removal of pharmaceutical residues from treated wastewater

    Pharmaceutical residues, which pass naturally through the human body into sewage, are in many cases virtually unaffected by conventional wastewater treatment. Accumulated in the environment, however, they can significantly impact aquatic life. The present study indicates that many pharmaceutical residues found in wastewater can be removed with activated carbon in a cost-efficient system that ...

  • Performance of a Powdered Activated Carbon (PAC) Augmented Activated Sludge Process Treating Semi-Aerobic Leachate

    Semi-aerobic leachate is characterized by organic matter (COD, BOD) which is relatively low in concentration and difficult to biodegrade. In conventional treatment systems, the low biodegradability is attributed to partial stabilization of leachate at the landfill. Biological treatment of leachate in Malaysia is not well established and any important data for the treatment ...
