  • Laboratory- and full-scale studies on the removal of pharmaceuticals in an aerated constructed wetland: effects of aeration and hydraulic retention time on the removal efficiency and assessment of the aquatic risk

    Pharmaceutical residues in wastewater pose a challenge to wastewater treatment technologies. Constructed wetlands (CWs) are common wastewater treatment systems in rural areas and they discharge often in small water courses in which the ecology can be adversely affected by the discharged pharmaceuticals. Hence, there is a need for studies aiming to improve the removal of pharmaceuticals in CWs. ...

  • Laboratory test report - the effect of scale formation on heat transfer coils

    Background EVAPCO, Inc. recently introduced new Evaporative Condensers and Closed Circuit Coolers which utilize extended surface coils. For decades extended “fin” surfaces have been used on heat transfer coils, often referred to as “finned coils” primarily in an effort to increase dry capacity. However, in the past the fin material was limited to carbon steel tubes ...

  • Scientists, a new quota species?

    Globally, marine conservation is high on the agenda. The need to protect and conserve species and habitats from deleterious anthropogenic impacts has never been of more concern than it is currently. However, that is not to say we, as a society, are achieving effective marine conservation, in fact we are far from it. Global summits have come and gone, as have the targets they set for marine ...

  • Environmental fate and behavior of acesulfame in laboratory experiments

    Acesulfame is a widely used artificial sweetener. It can be discharged into surface water by domestic wastewater due to its incomplete retention during wastewater treatment. Concentrations may reach up to 10 μg/L for smaller rivers. State-of-the-art analysis allows the determination of acesulfame traces (0.01 μg/L) and thus a potential tracking of the presence of wastewater in riverbank ...

  • Influence of nutrient supplementation on DOC removal in drinking water biofilters

    Analysis of the impacts of nitrogen, phosphorus and potassium supplementation on biofilter performance for organic carbon removal was studied on laboratory-scale biofilter columns. Three dual media biofilter columns were fed with synthetic raw water C:N:P ratios of 546:24:1, 100:10:1, and 25:5:1 (w/w) to simulate nutrient limited and two nutrient supplemented conditions, respectively. Research ...

  • Measurement Science and Technology Paper - Potential for improved radiation thermometry measurement uncertainty through implementing a primary scale in an industrial laboratory

    A primary temperature scale requires realising a unit in terms of its definition. For high temperature radiation thermometry in terms of the International Temperature Scale of 1990 this means extrapolating from the signal measured at the freezing temperature of gold, silver or copper using Planck's radiation law. The difficulty in doing this means that primary scales above 1000 °C require ...
