  • Biofilm carrier migration model describes reactor performance

    The accuracy of a biofilm reactor model depends on the extent to which physical system conditions (particularly bulk-liquid hydrodynamics and their influence on biofilm dynamics) deviate from the ideal conditions upon which the model is based. It follows that an improved capacity to model a biofilm reactor does not necessarily rely on an improved biofilm model, but does rely on an improved ...

  • Plastic debris and policy: Using current scientific understanding to invoke positive change

    Captain Charles Moore introduced the world to the “Great Pacific Garbage Patch” in the mid‐1990s, and images of plastic debris in the oceans began to sweep the media. Since then, there has been increasing interest from scientists, the public, and policy makers regarding plastic debris in the environment. Today, there remains no doubt that plastic debris contaminates aquatic (marine and ...

  • What will it take to get plastics out of the ocean?

    From drones to filters to artificial islands, innovators are working to reduce the threat thousands of tons of trash pose to marine ecosystems. A few palm trees stand strong in the salty breeze. Located on the southern tip of the Pacific island chain of Hawaii, Kamilo Beach is an isolated stretch of black volcanic shoreline in the middle of nowhere. Just a few hundred yards ...

  • Effects of physical disturbances on media and performance of household-scale slow sand (BioSand) filters

    Point-of-use (POU) water treatment provides households in rural and remote communities with a means of obtaining greater control over their water quality and its effects on human health. One of the most prevalent POU interventions, the BioSand filter (BSF), is a household-scale, intermittently operated slow sand filter used by over 300,000 households. The sand and gravel media within BSFs can be ...

  • Removal of nitrogen from secondary effluent of a petrochemical industrial park by a hybrid biofilm-carrier reactor with one-stage ANAMMOX

    A laboratory study was undertaken to explore the capability of one-stage ANAMMOX in a hybrid biofilm-carrier reactor (HBCR) fed with petrochemical wastewater. Under favorable operating conditions in continuous-flow operations (at the dissolved oxygen level of 0.5–1.0 mg L−1), the average total nitrogen (TN) removal efficiency reached 62–67% and approximately ...

  • Modelling clogging and biofilm detachment in sponge carrier media

    Sponge carrier media provide a large surface area for biofilm support; however, little information is known about how to model their dual nature as a moving bed and as porous media. To investigate the interaction of mass transfer and detachment with bio-clogging, a novel biofilm model framework was built based on individual-based modelling, and hydrodynamics were modelled using the lattice ...

  • The use of plastic media in a movable bed model to study sedimentary processes in rivers

    The use of plastic media was evaluated for modelling sedimentary processes in rivers using a movable bed model (MBM). From gradations within the range of 0.17–2 mm, the size of the thermoset plastic media was colour coded in order to better visualise complex flow processes. Equations developed by Engelund–Hansen and Schoklitsch were used to predict sediment transport and establish the type of bed ...
