    Boiler Water Testing / Cooling Tower Water Testing

    Boilers and cooling towers share two major water related problems: deposits and corrosion. As steam is generated by a boiler or water evaporating from a cooling tower, dissolved minerals are left behind, increasing the concentration of these minerals. Additional minerals are introduced via the water added to makeup the water lost to steam/evaporation. Eventually, the minerals reach a level (or cycle) of concentration that will cause either loss of efficiency due to scale or damage from corrosion. This level can be determined by the Ryznar or Langlier indices and correlated to a conductivity or TDS range. Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8` of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

    Precision moisture analysis instruments for rapid solids testing for pulp and paper

    Durable, reliable analysis for black liquor. Black liquor is a difficult substance to work with. It’s caustic, it’s toxic, and it emits poisonous gases such as hydrogen sulfide. But the efficient use of black liquor is critical to the profitable operation of any pulp and paper mill. In order to use black liquor efficiently, you need to test it for solids. Make sure your solids analyzer is up to the task.

    In-situ Reduction Technology of Groundwater Remediation Industry

    In-situ groundwater remediation method is based on injection of Fe(0) nanoparticles through application wells directly into the contaminated water. nZVI injection is very fast, reaching significantly lower operating costs compared to commonly used remediation methods (expensive construction of reactive barriers, building of pump&treat stations, excavation of contaminated soil etc.). In comparison to other in-situ technologies a far lower quantities of injected chemical is needed due to high efficiency of the product and thus the time and cost of remediation is reduced.

  • Analysing preservatives in recycled and treated wood for wood industry

    Treated wood for disposal or recycling is tested for hazardous components to establish the relevant methods of wood disposal that can be applied. There is a range of preservative solutions used for pressure treated wood including Copper Azole, Pentachlorphenol (Penta) and Chromated Copper Arsenate (CCA), all of which can be identified by analysis. While untreated wood degrades within three to five years, the wood that is pressure treated with these kind of preservatives can last up to sixty years!
