  • Controlling Stack Emissions in the Wood Products Industry

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...


  • Controlling acid gas mists

    Gas cleaning New and strict pollution regulations in metallurgical plants worldwide are restricting particulate and acid gas emissions to extremely low levels. Because of that, sulphuric acid plants are being installed to remove and utilise S02 in gases resulting from the roasting of sulphide ores, smelting of ores, and burning or regeneration of spent acid or acid sludge from ...

  • Particulate Control Strategies for Incineration

    Abstract This paper discusses various particulate emission control strategies that can be employed for Municipal Solid Waste (MSW), Municipal Sewage Sludge, and Industrial Waste Incineration facilities. An example will be given of a particulate control installation that successfully cleans off-gases from an incinerator at a large photographic products plant. Data supporting a theoretical ...


  • Thirty Years of Satisfactory Fluid Bed Sludge Incineration - The Northwest Bergen County Utilities Authority Experience

    ABSTRACT Fluid bed incineration has been used as a sludge disposal method at the Northwest Bergen County Utilities Authority since 1969 when the first incineration unit was installed. In 2000, the third generation plant became operational. Over this period, environmental regulations have changed, as have the State mandated air pollution control devices. Since the State mandated a wet ...
