  • Mitsubishi corporation - Spent Potliner (SPL) hazardous waste treatment case study

    The Challenge Spent Potliner (SPL) is generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. The SPL waste contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. Unless carefully handled, these contaminants readily "leach" into the surrounding soils and ...

  • Sensitivity of six subantarctic marine invertebrates to common metal contaminants

    A long history of anthropogenic activities in the relatively pristine subantarctic has resulted in areas of accumulated waste and contaminants. Sensitivities to metals of subantarctic and Antarctic species may contrast with related species from temperate and tropical areas, due to the unique characteristics of polar biota. In addition, response to contaminants may be delayed and hence longer ...

  • Effect of cathode electron acceptors on simultaneous anaerobic sulfide and nitrate removal in microbial fuel cell

    The current investigation reports the effect of cathode electron acceptors on simultaneous sulfide and nitrate removal in two-chamber microbial fuel cells (MFCs). Potassium permanganate and potassium ferricyanide were common cathode electron acceptors and evaluated for substrate removal and electricity generation. The abiotic MFCs produced electricity through spontaneous electrochemical ...

  • Quantification of exposure to fecal contamination in open drains in four neighborhoods in Accra, Ghana

    In low-income countries, rapid urbanization adds pressure to already stressed water and sanitation systems that are critical to the health of communities. Drainage networks, designed for stormwater but commonly used for disposing of waste, are rarely covered completely, allowing residents to easily come into contact with their contents. This study used spatial mapping, documentation of ...

  • Simultaneous pollutant removal and electricity generation in denitrifying microbial fuel cell with boric acid-borate buffer solution

    A double-chamber denitrifying microbial fuel cell (MFC), using boric acid-borate buffer solution as an alternative to phosphate buffer solution, was set up to investigate the influence of buffer solution concentration, temperature and external resistance on electricity generation and pollutant removal efficiency. The result revealed that the denitrifying MFC with boric acid-borate buffer ...

  • How to turn human waste into disease-free fertiliser

    Poor sanitation can contaminate drinking water, especially in rural areas. Unless properly dealt with, faeces and other human waste can pollute the soil and eventually wells, causing diseases such as diarrhoea. The EcoSanitation method provides a safe way to dispose of human waste. Today, a research project in Tanzania examines the potential of combining this system with a composting technique ...

  • Additives mixing effect fuel consumption

    Additives are an instrument of fuel operational development properties which can’t be provided with the previous stages of fuel producing. They lead to product correction, instead of participate in the main method of production. Their efficiency is caused by chemical structure, structure of a basic base, mutual influence and additives mixing process. Improvers which affect some parameters ...

  • Turning Contaminated Waste into Clean Renewable Energy and pas 110 compost – an overview of the inter Engineering Biowaste Process

    The Inter Engineering Biowaste process has been specifically developed to allow contaminated CAT3 organic wastes to be pre-conditioned and anaerobicly digested to produce high yields of renewable biogas and good quality compost suitable for compliance with the proposed PAS110 standard.   The paper outlines the process and discusses many of the specific adaptations the process has made to ...


  • Performance of microbial fuel cells on removal of metronidazole

    The microbial fuel cells (MFCs) are the focus of extensive investigation as one of the promising technologies for renewable energy generation and wastewater treatment. Two-chambered MFCs were designed to investigate the removal of metronidazole and to quantify the effect of antibiotic on the efficacy of energy generation. Using 1,000 mg glucose L−1 containing different concentrations of ...
