1. A device for controlling microbial growth in potable water systems, said device comprising:
- a flow-through housing having a housing wall structure, a housing volume surrounded by the housing wall structure, and one or more openings within the housing wall structure; and
fluid treatment media occupying at least a portion of the housing volume within the flow-through housing, said fluid treatment media comprising a physical mixture of;
a first set of particles or beads comprising an anti-microbial component coating on a support material with the anti-microbial component coating comprising one or more coating layers on said support material, said anti-microbial component comprising silver and said support material comprising alumina; and
a second set of particles or beads comprising a scale inhibitor comprising glassy polyphosphate particles;
wherein the support material has a particle size that prevents the support material from escaping the one or more openings within the housing wall structure.

2. A device for controlling microbial growth in potable water systems, said device comprising:
-
a flow-through housing having a housing wall structure, a housing volume surrounded by the housing wall structure, and one or more openings within the housing wall structure;
wherein the housing wall structure of the flow-through housing comprises;an upper half, a lower half connected to the upper half, and a filling cap connected to the upper half or the lower half;
said one or more openings being positioned within the upper half, the lower half, or both; andfluid treatment media occupying at least a portion of the housing volume within the flow-through housing, said fluid treatment media comprising (1) an anti-microbial component coating comprising silver on (2) a support material comprising alumina with the anti-microbial component coating comprising one or more coating layers on said support material, and (3) a scale inhibitor comprising glassy polyphosphate particles; wherein the support material has a particle size that prevents the support material from escaping the one or more openings within the housing wall structure. - View Dependent Claims (4, 7, 8)
