  • Controlling Stack Emissions in the Wood Products Industry & Wood Fired Boilers

    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 ...

  • Precipitator Solves Dryer Problem

    Plum Creek Manufacturing, Columbia Falls, Montana, installed a PPC Industries electrostatic precipitator to solve a direct fired dryer dust plugging problem. The electrostatic precipitator was installed in a very congested area and the project had to be done so the dryer was off-line a minimal amount of time. Plum Creek personnel relocated existing equipment, poured concrete footings, ran all of ...

  • High performance of nitrogen and phosphorus removal in an electrolysis-integrated biofilter

    A novel electrolysis-integrated biofilter system was developed in this study to evaluate the intensified removal of nitrogen and phosphorus from contaminated water. Two laboratory-scale biofilter systems were established, one with electrolysis (E-BF) and one without electrolysis (BF) as control. The dynamics of intensified nitrogen and phosphorus removal and the changes of inflow and outflow ...

  • Innovative wet electrostatic precipitators assure competitive edge in acid marketplace

    The unsteady global economic recovery continues to subject many core industries to persistent volatility in profits, prices, markets and capital investments. However, some analysts remain optimistic about the global international trade in sulfur in all forms, particularly sulfuric acid. This versatile mineral acid is both the world’s most widely used chemical, and the one with the highest ...

  • Cement and Lime Kilns case study

    Cement and Lime Kilns PROCESS DESCRIPTION Cement, lime and gypsum manufacturing processes have in common the mixing of inorganic minerals calcined at high temperatures typically using rotary kilns (vertical kilns are also used). CEMENT Regular Portland cements are the usual products for general concrete construction. The raw ...

  • Equilibrium analysis for heavy metal cation removal using cement kiln dust

    Ion exchange, reverse osmosis, and chemical precipitation have been investigated extensively for heavy metal uptake. However, they are deemed too expensive to meet stringent effluent characteristics. In this study, cement kiln dust (CKD) was examined for the removal of target heavy metals. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption ...
