  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...

  • Characterisation of humic acid maturation by fluorescence spectroscopy and thermal analysis during composting of olive mill waste

    Humic acids isolated from different stages of olive mill waste composting were investigated by Elemental analysis, Fluorescence spectroscopy and by Differential Scanning Calorimetry (DSC). The Elemental composition of these humic acids indicates an increase in aromatic structures during the composting. Indeed, the fluorescence results showed an increase in condensed aromatic ring systems. ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...

  • Activated bauxite waste as an adsorbent for removal of Acid Blue 92 from aqueous solutions

    Bauxite waste, known as red mud, is produced in some industrial processes, such as aluminum production process. In this process, the waste material is produced from leached bauxite as a by product. In this research, the removal of Acid Blue 92 (AB92) dye was investigated from aqueous solution onto the activated bauxite waste (red mud) in a batch equilibration system. Besides, the influences of ...

  • Komax teflon lined mixer simplifies acid injection for power plant

    A major source of waste water in many power plants is the waste stream that results from ion exchange used for demineralizing the boiler feed water. The alkaline regeneration waste stream produced by the ion exchange process requires the addition of an acid to this stream before discharge from the plant. Regulatory authorities typically require the effluent to have a near neutral pH before ...

  • Hydrochemical changes in a reservoir that receives water contaminated by acid mine drainage

    The aim was to characterize hydrochemical changes that take place in the Sancho reservoir, which receives waters contaminated by acid mine drainage (AMD) from the Meca River (Iberian Pyrite Belt, SW Spain). The sampling procedure comprised bimonthly campaigns carried out between October 2011 and May 2012, in the entrance of the reservoir and in the input river waters. In addition to in situ ...

  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

  • A Case Study For Thermal Treatment Of Fluorinated Hydrocarbon With 15% Wt Hydrofluoric Acid Recovery

    This paper is a joint presentation by 3M Specialty Materials and Selas-Linde to describe the thermal treatment technology used to safely destroy Fluorinated Hydrocarbon components generated as a result of fluorination of organic compounds. Thermal treatment of these components results in high concentration of Hydrogen fluoride in the combustion chamber requiring special attention to handling and ...

  • The East-Sullivan Mine Site: Merging Prevention and Treatment of Acid Mine Drainage - update

    ABSTRACTThe East Sullivan mine was closed in 1966, leaving 15 Mt of acid-generating tailings free to contaminate theenvironment. An experimental wood waste cover was implemented in the early 80's in order to prevent sulphideoxidation. Contaminant production and dispersion were investigated in the 90's to validate that concept and guide lateractions. Ligneous wastes stop oxygen, and also favour ...

  • Effect of low cost activated carbon on the photocatalytic degradation of Acid blue 158 from aqueous solution

    The photocatalytic degradation of Acid blue 158, an anionic dye was carried out using the mixture of activated carbon prepared from sugar mill waste bagasse (BC) and TiO2 (BC + TiO2) under UV irradiation. Adsorption studies using BC and photodegradation using TiO2/UV were also carried out for ...

  • Toxins Found in E-Waste

    One of the worst effects of a skyrocketing, global e-waste crisis is the risk of toxic contamination for the environment and communities. In fact, delving into the many chemical and heavy metal materials that make up most electronic devices, it seems that toxins and electronics go hand in hand. Though many manufacturers of electronic devices are finding innovative ways to work around toxins found ...

  • Minicipal Waste Incinerator Case History

    Low temperature plant operation had resulted in severe baghouse corrosion and constant dust blockages throughout the system. It was decided to raise the operational temperature of the incinerator and change the acid gas scrubbing agent from lime to sodium bicarbonate. However, the existing felt filter media could not cope with the change in acid gas scrubbing agent and “blinded” very rapidly ...

  • Development of a highly specific and productive process for n-caproic acid production: applying lessons from methanogenic microbiomes

    High productivity and specificity in anaerobic digesters arise because complex microbiomes organize into a metabolic cascade to maximize energy recovery and to utilize the advantage that the gaseous end product methane freely bubbles out of the system. These lessons were applied to ascertain whether a reactor microbiome could be shaped to produce a different end product. The liquid product ...

  • Medical waste management - quarterly journal

    Routine inspections at laboratories have found a pattern of hazardous waste management problems in recent years. EPA has discovered chemicals forgotten in university stockrooms for decades, a research lab with wastes in damaged containers, some labeled “unknown”, and a hospital storing a chemical at almost twice the temperature at which it could explode. Improper disposal of waste is ...


  • Waste Water Treatment Processes Explained
