  • Treatment of tannery wastewater for reuse by physico-chemical processes and a membrane bioreactor

    Treatment of wastewater from a tannery in Greater Ho Chi Minh City (Vietnam) was investigated on a pilot scale. After pre-treatment by the tannery that included batch-coagulation and sedimentation, the wastewater was treated by dissolved air flotation, a membrane bioreactor (MBR) and granular activated carbon (GAC) for polishing the MBR effluent. The average removal efficiency for organic ...

  • 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 ...

  • Pd/RGO modified carbon felt cathode for electro-Fenton removing of EDTA-Ni

    Ethylenediaminetetraacetic acid (EDTA) forms stable complexes with toxic metals such as nickel due to its strong chelation. The electro-Fenton (EF) process using a cathode made from palladium (Pd), reduced graphene oxide (RGO) and carbon felt, fed with air, exhibited high activities and stability for the removal of 10 mg L−1 EDTA-Ni solution. Pd/RGO catalyst was prepared by one-pot synthesis; ...

  • TCE Source Area Remediation at a Former Manufacturing Facility Confidential Client – Western Connecticut - Case Study

    Project Summary TRS Group, Inc. (TRS), as a subcontractor to AECOM, completed a Standard Fixed Price Remediation (SFPR) of trichloroethene (TCE) in groundwater in Western Connecticut using Electrical Resistance Heating (ERH). The objective of the ERH project was to achieve the prescribed remediation goal for dissolved TCE in groundwater within the treatment volume. The system ...

  • Odor removal by powdered activated carbon (PAC) in low turbidity drinking water

    The potential of powdered activated carbon (PAC) adsorption for odor removal in low turbidity drinking water was investigated. The batch experiments were conducted under various conditions including PAC species, dosage, contact time and dosing point. The effects of pre-chlorination and PAC dosage on turbidity were also studied. Results showed that adsorption was quite vulnerable to initial ...

  • Legionnaires is an Air Quality Risk

    The recent Bronx, NY outbreak of Legionnaires infections is a grim reminder of the deadliness of this strain of pneumonia. Like many of the outbreaks, cooling towers caused this one. Twenty have been identified but the search is still going on. Over 120 people were infected and 12 have died. Tragically it affects the most vulnerable people–people with one or more immune system deficiencies. ...

  • Mercury sorption by silica/carbon nanotubes and silica/activated carbon: a comparison study

    Nanocomposites of silica incorporated with carbon nanotubes (silica/CNT) and activated carbon (silica/AC) were synthesized and characterized by scanning electron microscopy (SEM), element mapping, energy dispersive X-ray spectroscopy (EDX), thermogravimetric analyzer (TGA) and Fourier transform infrared spectroscopy (FTIR). Silica/CNT and silica/AC were investigated for efficient removal of ...

  • The Elimination of Ethylene in Domestic Refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Eliminating ethylene from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...

  • Characterization of air plasma-activated carbon nanotube electrodes for the removal of lead ion

    Carbon nanotube electrodes were prepared by pressing a mixture of carbon nanotubes and polytetrafluoroethylene (which acted as a binder) on a stainless steel net collector, and the electrodes were subsequently activated in our self-designed plasma apparatus, using air plasma. The morphology and surface functional groups of the electrodes were characterized using scanning electron microscopy and ...

  • Evaluating odour control technologies using reliability and sustainability criteria – a case study for water treatment plants

    Technologies for odour control have been widely reviewed and their optimal range of application and performance has been clearly established. Selection criteria, mainly driven by process economics, are usually based on the air flow volume, the inlet concentrations and the required removal efficiency. However, these criteria are shifting with social and environmental issues becoming as important ...

  • The Trouble with Asbestos Disposal

    Hailed as a miracle mineral because of its superior fire resistance and tensile strength, asbestos was installed abundantly into our built environment for over 200 years. However, once it was established that this undeniably useful resource was a dangerous carcinogen, Australia and many other countries enacted strict regulations for handling asbestos and asbestos containing material (ACM). There ...

  • Is H2S a suitable process indicator for odour abatement performance of sewer odours?

    Odour abatement units are typically designed and maintained on H2S concentrations, but operational failures are reported in terms of overall odour removal, suggesting a wide range of malodorous compounds emitted from sewers that may not be efficiently removed by existing odour abatement processes. Towards providing greater insight into this issue, several activated carbon filters and biofilters ...
