Abstract: An electrodialysis cell includes a housing defining an internal chamber, a core positioned within the internal chamber, a first electrode positioned in the internal chamber adjacent the housing, a second electrode coupled to the core and spaced from the first electrode, and a membrane assembly positioned between the first and second electrodes in a spiral wound configuration. The housing includes an inlet end for receiving a feed fluid and an outlet end in fluid communication with the inlet end. The membrane assembly includes a plurality of ion exchange membranes spaced from each other to define a plurality of fluid channels between the inlet and outlet ends.

Abstract: A reverse osmosis unit for processing a feed solution is provided. The unit includes a pressure vessel includes an inlet end, an outlet end, and a vessel body extending between the inlet end and the outlet end. The reverse osmosis unit further includes a plurality of first membrane modules positioned within the pressure vessel. Each first membrane module of the plurality of first membrane modules has a first salt permeance value. At least one second membrane module is positioned within the pressure vessel and coupled in flow communication to the plurality of first membrane modules. The at least one second membrane module has a second salt permeance value that is different from the first salt permeance value.
