Patent ID: 8393350

Claim:
A method for using an additive introduction apparatus, the method comprising: causing a fluid supply to flow through the additive introduction apparatus; and activating the additive introduction apparatus to add an additive into the fluid supply, wherein activating the additive introduction apparatus includes manipulating an additive vessel of the additive introduction apparatus with respect to a primary flow fixture of the additive introduction apparatus by rotating the additive vessel about a central axis so that nozzle assemblies of the primary flow fixture are aligned with ports of the additive vessel, thus activating the nozzle assemblies by pressure exerted by the ports to divert a portion of the fluid supply into the additive vessel, wherein the portion of the fluid supply may mix with the additive within the additive vessel, and the portion of the fluid supply containing the additive may exit the additive vessel and re-combine with the fluid supply flowing through the primary flow fixture.
