  • 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 ...

  • Cost effective refilling of activated carbon filter

    The leachate from a landfill in North Rhine-Westphalia, Germany, used to be transported by road tanker to the nearest sewage treatment plant. Since 1998 a biological treatment plant has been in operation, which has nowhandled more than 650,000 m3 of leachate, at a maximum rate of 350 m3/day. Four activated carbon filters, each filled with 20 m3, handle the residual COD load. The wastewater is fed ...


  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • 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 ...

  • Biological Filtration: Future of Drinking Water Treatment

    Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. ...

  • 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 ...

  • 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, ...

  • Identification of bacteria assimilating formaldehyde in a biological activated carbon filter by means of DNA stable isotope probing and next-generation sequencing

    Ozonation followed by a biological activated carbon (BAC) filter is a common process of advanced water purification. Ozone can generate formaldehyde (FA) as a harmful by-product, while the subsequent BAC filter is efficient at removing FA. FA adsorption is limited on activated carbon because of its hydrophilic property and low molecular weight. Thus, biological degradation by biofilms ...

  • Bio-enhanced activated carbon filter with immobilized microorganisms for removing organic pollutants in the Songhua River

    Five dominant microorganisms including four kinds of Pseudomonas and one kind of Bacillus were isolated from the Songhua River. The organic pollutants removal potential and community composition of these five dominant microorganisms immobilized on activated carbon filter, which is called the bio-enhanced activated carbon filter (BEAC), were investigated to compare with the ...

  • Excess propagation and disinfection control of Copepod in an ozone-granular activated carbon filter in southern China

    The reasons for the excess propagation of Copepod in an ozone-granular activated carbon filter were investigated and batch experiments were conducted to analyze the influences of CT value, pH and organic matter on the efficiency of disinfection of Copepod using chlorine and chloramines. The experimental results revealed that Copepod accounted for 70% of the zooplankton in the sand filter effluent ...

  • Removal of bromate and natural organic matter by using biologically activated carbon

    The removal of bromate and Natural Organic Matter (NOM) during the transition from fresh GAC to BAC was investigated by using two GAC filters with different type of GAC. The removal of bromate, nitrate, NOM in GAC filter apparently decreased during the transition. Although high level of anions and NOM, and high pH value may greatly affect bromate reduction in GAC filter, in initial period one GAC ...

  • Removal of micropollutants with coarse-ground activated carbon for enhanced separation with hydrocyclone classifiers

    One key technology to eliminate organic micropollutants (OMP) from wastewater effluent is adsorption using powdered activated carbon (PAC). To avoid a discharge of highly loaded PAC particles into natural water bodies a separation stage has to be implemented. Commonly large settling tanks and flocculation filters with the application of coagulants and flocculation aids are used. In this study, ...

  • 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 ...

  • Effect of low dosages of powdered activated carbon on membrane bioreactor performance

    Previous research has demonstrated that powdered activated carbon (PAC), when applied at very low dosages and long SRTs, reduces membrane fouling in membrane bioreactors (MBRs). This effect was related to the formation of stronger sludge flocs, which are less sensitive to shear. In this contribution the long-term effect of PAC addition was studied by running two parallel MBRs on sewage. To one of ...

  • 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 ...
