    Abstract: A desalination system comprises at least one desalination cell. The at least one desalination cell comprises first and second electrodes, an anion exchange layer and a cation ion exchange layer disposed on the respective first and second electrodes, and a spacer disposed between the first and second electrodes. The at least one desalination cell further comprises an ion exchange resin disposed between the first and second electrodes. A desalination system and a method for removing ions from an aqueous stream are also presented.

    Abstract: In an apparatus and process described, an organic fraction of solid waste is separated from light contaminants such as plastics and heavy contaminants such as grit. The organic fraction is subsequently processed by anaerobic digestion, which converts volatile solids to gas. In a first stage of the process, the waste is processed through a separator such as a vertical mill, which removes light fraction contamination, reduces organics particle size and dilutes the waste to thereby produce a slurry. In a second stage of the process, the slurry passes through a grit removal system, which removes heavy and settleable material, for example by way of a hydrocyclone. The light and heavy fraction contaminants are not carried through to the digestion process. The particle size of the organics is also reduced to facilitate digestion and the slurry has a dry solids concentration suitable for anaerobic digestion.

    Abstract: An overgrowth of worms can reduce the effluent quality of a membrane aerated biofilm reactor. A method of controlling the growth of worms in a membrane aerated biofilm includes discontinuing all oxygen sources to a tank containing the biofilm and fluid flows flow into the tank. The tank is maintained in this idle condition for a period of time sufficient to kill at least some of the worms living in the biofilm. The method may be applied periodically to inhibit the formation of an excessive population of worms or retroactively to reduce an already excessive population of worms.

    Abstract: Various implementations include a reversible flow sampler including a housing, a housing cover, and a shuttle. The housing defines a sampler chamber with an inlet and an outlet, a first opening, and a second opening. The shuttle is movably disposed within the housing and coupled to the housing cover. The shuttle has a first shuttle position and a second shuttle position. In the first shuttle position, the shuttle fluidly connects the first opening with the sample chamber inlet and fluidly connects the second opening with the sample chamber outlet. In the second shuttle position, the shuttle fluidly connects the second opening with the sample chamber inlet and fluidly connects the first opening with the sample chamber outlet.
