  • 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 ...

  • 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 ...

  • 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 ...

  • Waste Water Batch Treatment System

    Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...

  • 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 ...

  • TKN determination in water and waste water

    Determination of TKN (Total Kjeldahl Nitrogen) in Water and Waste Water according to the Kjeldahl Method. The determination of TKN in water and waste water is a routine procedure for quality assurance. A simple and fast procedure for the TKN determination in water, according to ISO 5663, AOAC 973.48 and EPA 351.3, is introduced below. The sample is digested with sulfuric acid and the ...

  • Treating organic waste with Cambi THP

    ABSTRACT This paper describes how the Cambi Thermal Hydrolysis Process (THP) treats biodegradable organic waste and converts it to renewable energy and pathogen-free and bio-fertilizer. The interest for the process is expected to increase due to new environmental legislation as well as increasing demand for renewable energy. The implementation of the European Landfill Directive 1999/31EC and the ...

  • Water mixing in waste lagoons

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

  • 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 ...

  • Two-phase anaerobic co-digestion of food waste and sewage sludge

    The feasibility and performance of food waste and sewage sludge co-digestion were investigated to gain insight into their resource utilization. In this study, two-phase anaerobic digestion (TPAD) was operated under a total solids mixing ratio of 1:1 and different sludge retention times (SRTs). Results show that an acidogenic reactor with a 5-day SRT obtained the highest acidification efficiency, ...

  • Alkaline fermentation of waste activated sludge stimulated by saponin: volatile fatty acid production, mechanisms and pilot-scale application

    Volatile fatty acid (VFA) production stimulated by saponin (SP), an environmentally friendly bio-surfactant, was investigated during sludge alkaline fermentation in laboratory studies and pilot applications. The combined use of SP and pH 9 condition significantly enhanced VFA production to approximately 425 mg COD/g VSS, which was 4.7-fold of raw sludge and 1.5-fold of sole pH 10 adjustment ...
