Selectable media filter and sparger assemblies and related methods of fabrication and use

A selectable media filter and sparger assembly comprising:

• a housing, defining a unitary solid housing, extending from a first end that defines a solid endcap to a second end that defines a manifold;
• a plurality of porous members attached to the housing, each porous member of the plurality of porous members being tubular shaped, defined by a porous tubular wall, and extending around a center of the housing, from the first end to the second end of the housing, wherein the plurality of porous members are fabricated with different pore structures and/or densities relative to each other for a flow to pass therethrough at different rates;
• and
• a plurality of connection ports disposed at the second end of the housing and extending away from the second end of the housing, each connection port of the plurality of connection ports is tubular shaped and connected to one of the porous members,
• wherein, in operation, a flow is configured to flow separately, via one or more of:
• (i) into one or more of the plurality of porous members of the assembly via one or more of the plurality of connection ports, and out of the assembly via pores in the one or more plurality of porous members;
• and
• (ii) into one or more the plurality of porous members of the assembly via pores in the one or more plurality of porous members, and out of the assembly via the one or more of plurality of connection ports that are fluidly coupled to the one or more of the plurality of porous members, and
• wherein the selectable media filter and sparger assembly is fabricated at least in part by additive manufacturing, such that the housing, porous members and connection ports form a unitary assembly.
