  • Thermal waste gas purification of siliceous organic compounds - Case Study

    Example: Electrical industry Similar tasks: Electronic industry, Coating, Waste management When coating mica insulation materials, peaks of high contamination occur. The exhaust air containing organic compounds generates excess heat when oxidised in the regenerative thermal oxidiser (RTO). The properties of ceramic honeycomb blocks allow for the storage of that excess heat, for the ...

  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...

BP produces around 30 million tones per year which is 30 % of the worlds production of PTA. The TPA ...

  • Waste Gas in Metal Recycling: Hydrocarbons and carbon monoxide - Case Study

    Example: Aluminium recycling Similar tasks: Recycling of copper, lead, cink The waste gas in metal recycling usually contains particles (abraded metal, mineral dust), inorganic, acid substances (HF, HCI, SOx) and dioxins (PCDD/F) as well as a whole range of organic substances (unburned hydrocarbons) and carbon monoxide. Particularly, in the group of unburned ...

  • Top 3 Uses of Activated Carbon

    Activated carbon is an effective purifier. It is used to remove organic pollutants from different gaseous, liquid and solid substances. By removing the undesirable organic compounds, activated carbon can successfully remove the odour and taste of these compounds from a wide range of things.  Unlike other purification agents that react with organic compounds and change their nature, activated ...

  • Case Study: 3 pilot projects sponsored by the European Union - LIFE-Program

    Certain waste waters - such as streams from food and beverage industries, leachate waters from municipal waste dumping sites or drinking water purification - are invariably putting highly problematic strains on the environment. Many years of basic research as well as comprehensive test runs with a technical scale demonstration unit model have shown that the Ultrasonic Systems GmbH (USS) is in the ...


  • Like a phoenix from the ashes

    Thanks to growing environmental awareness, waste is increasingly being separated and recycled. However, residual waste always remains that can't easily be recycled. This ends up in waste incineration plants (referred to as KVAs in Swiss German) for disposal and reclaiming, such as the KVA Linthgebiet in Niederurnen in the Swiss canton of Glarus. Due to the strict environmental specifications ...

  • Fluid control saves $1 million at automotive supplier

    The Problem: A Michigan wheel manufacturer was facing numerous problems associated with the quality and maintenance of their coolant and cleaners. These problems included downtime quality control rejections due to corrosion of parts, pumps clogging with biological matter, and operator complaints of coolant odors. Concurrently, the plant needed to reduce fluid-related costs and improve data ...

  • Mobile service saves $46,700 in metalworking fluid system

    The Problem: An engine manufacturer had been having trouble with tool life, filtration performance and oil misting. To remedy the problem, the central system was partially discarded and replaced on a routine basis. The systems ranged in size from 8,000 to 40,000 gallons, and, while dumping was helping the problem, fluid costs were unacceptably high. The manufacturer and their contracted CMP asked ...

  • Particulate matter, halogen and aerosols - Case Study

    Example: Production of anodes for aluminium smelters as well as electronic industry (TFT-LCD) Similar tasks: Carbon and graphite industry, smelting of aluminium, coating of metals An anode producer has several ring furnaces to stabilise the anodes by carbonization for later processing in a melting bath. The hot exhaust gases pass through double walls in between the anodes where the gases ...

  • Dioxines and furanes - Case Study

    Example: Scrap copper recycling, cobalt for battery production Similar tasks: Metal recycling, roast processes, thermal waste disposal When recycling metals - as in scrap copper recycling (mostly cable material) - toxic waste gases often occur. The raw materials to be recycled are injected in a shaft kiln that emits dust, organic contaminants, carbon monoxide, dioxins as well as furans. A ...

  • A STIEFEL project UTO Uvrier case study
