Abstract: An active flash-light treatment system is configured to degrade organic pollutants in a liquid stream. The system includes a reactor configured to receive the liquid stream, a light source configured to generate an emitted light having a first wavelength range, an upstream sensor configured to measure a characteristic of the liquid stream before entering the reactor, and a controller configured to analyze the characteristic of the liquid stream and to select a wavelength-conversion material for the reactor, based on the characteristic of the liquid stream. The wavelength-conversion material is configured to absorb the emitted light and generate a converted light having a second wavelength range, different from the first wavelength range, and the converted light irradiates the liquid stream to degrade the organic pollutants.

Abstract: An inter-tenancy partitioning system installed between floor and ceiling slabs has aligned dual spaced apart ceiling and floor channels formed by channel forming members. Dual panels are supported vertically within the aligned dual ceiling and floor channels Each panel having a width less than that of each channel and the channels are spaced apart to provide a gap between the panels. The panels have a height of greater than 2800 mm and extend through a suspended ceiling to engage the respective channel forming members at the ceiling slab above the suspended ceiling. Outer vertical pieces of the channel forming members of the floor channels have a height that does not extend vertically beyond an upper surface of the adjacent floor covering.

Abstract: Provided herein is a universally applicable biofouling mitigation technology using acoustically excited encapsulated microbubbles that disrupt biofilm or biofilm formation. For example, a method of reducing biofilm formation or removing biofilm in a membrane filtration system is provided in which a feed solution comprising encapsulated microbubbles is provided to the membrane under conditions that allow the encapsulated microbubbles to embed in a biofilm. Sonication of the embedded, encapsulated microbubbles disrupts the biofilm. Thus, provided herein is a membrane filtration system for performing the methods and encapsulated microbubbles specifically selected for binding to extracellular polymeric substances (EFS) in a biofilm.

Abstract: An in-situ, non-destructive sensor device, system and method are provided to detect or assess fouling at a very early stage of development. They can be used to detect or assess fouling on a surface of an aquatic system. They can be used to obtain a depth profile of the fouling. Data concerning the depth profile can be extracted and used to assess the fouling on the surface. In one or more aspects, the method can include providing an optical tomography spectrometer; optically positioning the optical tomography spectrometer in association with a surface of an area to be assessed for fouling in an aqueous system; irradiating the surface; acquiring, from irradiating the surface, a plurality of signals as a function of a distance from the surface at different times; extracting data from the signals as a function of the distance to obtain a depth profile of the surface at the different times; and determining a change in the depth profile between the different times to assess fouling on the surface.
