  • Transportation of digested sludges over extreme distances

    Sludge is a residual product of sewage treatment that, as a rule, is digested and concentrated. In larger processing plants, it is dehydrated, partially dried and subsequently utilised in other processes. This usually takes the form of incineration and subsequent use as an additive to building materials by the cement industry. In the sewage treatment plant (STP) of the local authorities ...

  • Columbus, Georgia`s High-Efficiency, Low Cost, Digester-Gas-Fired Power Plant

    ABSTRACTGrowing concern over the cost of power and long-term availability of limited fossil fuel resources for the production of electricity have caused electrical utilities and governments to promote “green” or renewable power. Solar, wind, geothermal, biomass, biogas, and low-impact hydroelectricity are current acceptable green-power sources. Digester gas is a renewable, green energy resource ...

  • Effect of different solid concentration on biogas yield and composition during anaerobic fermentation process

    The anaerobic fermentation experiments were carried out on a self-manufactured bench scale anaerobic digester with pig dung as feed material.

  • Determination of arsenic in baby foods and fruit juices by GFAAS

    The United States does not have specific regulations specifying the allowable levels of toxic elements in foods, but many other countries do. For example, Canada has a specific tolerance level for arsenic of 0.1 ppm in ready to serve fruit juices, nectars, and beverages1. The toxic nature of arsenic is such that chronic exposure to the element can lead to internal cancers of the bladder and ...

  • Turning waste into power

    Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power.

  • Cleaning biogas with bacteria

    Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid ...
