  • Monitoring Phenol in Water

    The Situation A plant located in the eastern United States manufactures phenolic resin for applications in plastics molding. This plant uses well water for cooling its reaction process and then discharges the water into a local creek. A leak in the reactor and associated cooling equipment would cause phenol and phenolic compounds to contaminate the cooling water. Such a leak could ...

  • Zero discharge system handles german power station’s fgd wastewater

    Evaporator/Crystallizer Combined with Salt Exchange Pretreatment is the Answer for this Demonstration Plant. The Facility A major European utility has several power block units fitted with wet limestone FGD scrubbers at their 600 MW power station in southern Germany. The blowdown from the scrubbers is treated to remove the heavy metals and suspended solids. The ...

  • Increasing condenser capacity without adding tubes to support a station uprate

    Abstract A station uprate provides an economical opportunity to improve the generation capacity of a power plant if all the major system components are able to handle the effects of increased generation. The magnitude of uprate from increased steam generation will be limited by the maximum capacity of the weakest link in the cycle, which for many plants is the condenser. The condensers ...

  • Adsorption of Trihydroxamate and Catecholate Siderophores on -iron (Hydr)oxides and their dissolution at pH 3.0 to 6.0

    The adsorption of desferrioxamine (DFOB), acetyl desferrioxamine (DFOD1), and a catecholate derivative (DFOMTA)] on goethite (-FeOOH) and hematite (-Fe2O3) and mineral dissolution behavior at pH 3.0 to 6.0 were studied to yield an understanding of the mechanisms of siderophore complexation on  phases and also to study how variations in siderophore molecular structure, as modified by proton ...

  • Poultry Food Short

    This facility processes, seasons, cooks, and flash-freezes poultry products and wanted to increase their production. The existing wastewater system could not meet the discharge requirements to the local POTW (city) and more stringent limits were imposed as a condition of their expansion. The facility was looking at a tremendous capital improvement cost to increase the size of their wastewater ...

  • A new approach to drilling waste management – prevention!

    Grangemouth based Surface Active Solutions (SAS) has developed its microemulsion based technology to aid the prevention and management of drilling waste. The many activities surrounding the removal of drilling mud in surface and downhole cleaning applications usually generate significant volumes of oil contaminated drilling waste. The drilling mud is typically removed through the use of solvents ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...

  • Is it time to recycle more nickel?

    Now you might think me a little sad, but I have to confess that as a metallurgist, I always find it interesting just how closely the history of mankind is linked to advances in metal working. The first evidence of metal working in Europe dates from around 5500 BC with the extraction of copper, lead and precious metals and this was followed by the working of bronze from around 4000 BC, both of ...

  • Least-Cost Approaches to Reducing Acid Emissions

    ' The costs of meeting sulfur emission targets can be high. It is essential, therefore, that countries adopt policies which (a) minimize the net economic and social costs of reducing emissions to the agreed target levels, and (b) maximize the overlap between measures designed to reduce acidifying emissions and those addressing other forms of air pollution. This note discusses alternative ...

  • Environmental Effects of Acid Rain

    Air Pollution Creates Acid Rain Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Acidic deposition, or acid rain as it is commonly known, occurs when emissions of sulfur dioxide (SO2) and oxides of nitrogen (NOx) react in the atmosphere with water, oxygen, and oxidants to form various acidic compounds. This mixture forms a mild ...
