  • 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 efficient cyclone systems with electrostatic recirculation for particulate matter (PM) emission control

    The development of new optimized dedusting systems has particular and increasing relevance for atmospheric particulate emission control. Indeed, traditional "particulatetraps" present several disadvantages that foster the search for alternative solutions. Industrial cyclones are, for their robust construction, absence of moving parts and general application, an appropriate technology for emission ...

  • Possible reuse of Egyptian controlled cement dust

    Possibilities for the reuse of controlled cement dust, collected from the hopper of the electrostatic precipitators installed on the different cement kilns of two of the three biggest companies for Portland cement production located to the south of Cairo, have been investigated. Twenty-one factors representing the physical properties and mineral and chemical composition of the cement dust were ...

  • 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 ...

  • The implement of the electro-static and magnetic precipitation technique through the centeral air-conditioning systems

    In this paper we will introduce the electrostatic and magnetic precipitation technique, to deposit the solid dust within the air–conditioning systems .Recently such technique becomes a very important subject for human life and to the college and universities, both the teaching, and researching programs. Viruses can be spread very fast, where the central air-condition systems probably take the ...


  • 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 ...


  • New ion exchange processes for brine purification

    Three new ion exchange processes have recently been developed for purification of brine. The PDP (precipitator dust purification) process removes chloride contamination from byproduct sodium sulphate recovered from the electrostatic precipitator ofakraft pulp mill's recovery boiler. The BDS (brine de-sulphurization) process removes sulphate impurities from chlor-alkali cell brines, while a novel ...

  • 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 ...

  • Water Innovations Facility Upgrade

    A few facility upgrades at Water Innovations worth mentioning this quarter at our San Diego 10,000 square foot facility. As we continue to hire a growing workforce across departments, and several years of our continued investment and growth. We have invested in an Electrostatic Precipitator, to use in our in-house paint both. This is a device that removes suspended dust particles from a ...

  • Characterisation for some emission sources in CMB calculation for Mae Moh area, Thailand

    Particulate samples of agricultural waste burning, straw burning, forest leaf burning, heavy duty truck emission, paved road dust, soil, agricultural soil, coal, electrostatic precipitator ash, and emission from stack power plant were collected from the Mae Moh area. Chemical compositions of sampling filters were analysed to determine the particulate matter source profiles. The analysis included ...

  • Smelter gas cleaning one vessel from the quench to the drying tower

    Base metals such as zinc, lead and copper are all found in nature bound with sulphur as sulphite minerals: sphalerite (ZnS), galena (PbS), several copper minerals, silver (found as acanthite Ag2S), and, along with other precious metals. Processing of the metals invariably leads to sulphur dioxide (SO2) formation. Other metal processing, such as aluminum from bauxite ore [Al(OH)3] which contains ...

  • Static and dynamic back-corona characteristics

    Voltage-current characteristics are a basic tool to analyse the operational conditions of an electrostatic precipitator, and to detect the onset of Back-corona, that strongly affects the collection performances. In this investigation, a laboratory set-up has been arranged, with a classical ESP wireplate configuration; both static and dynamic voltage-current characteristics have been measured and ...
