  • PPCPs: Preparing for an uncertain regulatory future

    A recent study published in Environmental Pollution* identified 56 active pharmaceutical ingredients (APIs) in effluent samples from 50 large wastewater treatment plants across the U.S. Among the products found in samples were commonly prescribed anti-psychotic and antihypertensive drugs. As more studies continue to fuel public concerns over risks to public health and the environment, wastewater ...

  • Shellfisheries: Time to prepare for ocean acidification

    Both physical and social factors must be considered as coastal communities brace for an uncertain future. Oceans are gradually becoming warmer and more acidic as more carbon dioxide enters the atmosphere — two shifts that are altering the economic foundations of many coastal regions. In a ...

  • Fuel preparation technology – the latest safety considerations

    The specifications for new fuel preparation technologies are becoming increasingly sophisticated, as industry innovation continues apace. But when it comes to investing in waste shredders that help manufacture cement fuels, which criteria should top the procurement wish-list in 2018? With more than 25 years’ experience in this sector, Peter Streinik, head of UNTHA’s waste shredding ...

  • Quick start-up of membrane bioreactor for treating micro-polluted surface water under low temperature

    This paper proposed an enhancement start-up strategy for accelerating the start-up of a membrane bioreactor (MBR) for treating micro-polluted surface water under low temperature. The surface water ammonia oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) were firstly enriched in a culture apparatus, and they were further acclimated to surface water through an MBR. Then the prepared ...

  • Degradation of Amaranth azo dye in water by heterogeneous photo-Fenton process using FeWO4 catalyst prepared by microwave irradiation

    FeWO4 particles were synthesized by a simple, rapid and facile microwave technique and their catalytic properties in heterogeneous photo-Fenton reaction were evaluated. This material was employed in the degradation of Amaranth azo dye. Individual and interactive effects of operational parameters such as pH, dye concentration and H2O2 dosage on the decolorization efficiency of ...

  • Batch blenders make modern mortars in China

    With no internal moving parts, blenders minimize abrasive wear and simplify cleaning at two SureBlock plants. In 1997, US-based SureBlock entered a joint venture with China's Tianjin People's Building Material Products Factory to make concrete masonry units (CMUs). Commonly known as concrete blocks, CMUs come in many shapes, sizes, and colors. They are mainly used to erect structural walls, ...

  • Suppressive subtractive hybridization libraries prepared from the digestive gland of the oyster Crassostrea brasiliana exposed to a diesel fuel water‐accommodated fraction

    Diesel fuel can cause adverse effects in marine invertebrates by mechanisms that are not clearly understood. The authors used suppressive subtractive hybridization to identify genes up‐ and downregulated in Crassostrea brasiliana exposed to diesel fuel. Genes putatively involved in protein regulation, innate immune, and stress response, were altered by diesel challenge. Three genes regulated by ...

  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • Effects of current density on copper nanoparticle prepared by electrochemical method

    Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...
