  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • Do you know the two most important words required to understand oil spill booming?

    Much has been written (incorrectly) about how to deploy boom in order to protect, deflect or contain oil. We have long promoted using math and science when deploying spill countermeasures not only because it works, but because it’s faster, safer, more effective and it saves time, money and impact. What we’ll focus on in this article is the where of ...

  • Erratum: Water Science and Technology 72 (7): Development of a new wastewater treatment process for resource recovery of carotenoids, H. Sato, H. Nagare, T. N. C. Huynh and H. Komatsu, doi: 10.2166/wst.2015.330

    A new wastewater treatment process that involves coagulation, ozonation, and microalgae cultivation has been developed. Here, two challenges are discussed. The first was minimizing phosphorus removal during coagulation in order to maximize algal production. The second was to optimize microalgae cultivation; algal species that grow rapidly and produce valuable products are ideal for selection. ...

  • Performance measurement of a twisted three-bladed airfoil-shaped H-rotor

    In the present study, performance of a twisted three-bladed airfoilshaped H-rotor was measured experimentally for different values of chord Reynolds number of flow and ratios of height-to-diameter (H/D). The rotor was 20 cm in height (H) and 5 cm in chord with about 26° twist at the trailing end. Tests were conducted in an open circuit subsonic wind tunnel for ten H/D ratios, namely 0.85, ...

  • Degradation of carbendazim by UV/H 2O 2 investigated by kinetic modelling

    Abstract The transformation of the fungicide carbendazim (methyl-2 benzimidazole carbamate) induced by hydroxyl radical generated by the UV photolysis of H 2O 2 has been studied in dilute aqueous solution. The efficient reaction of hydroxyl radicals with carbendazim led to the rapid degradation of carbendazim. The study of reaction kinetics yielded a second order rate constant of 2.2±0.3 10 9 M ...
