Passive-fluid dosing assembly

A passive fluid dosing system comprising:

• a dosing head including a sidewall defining a fluid inlet for the receipt of a flowing liquid, the dosing head including a pressure plate defining an internal orifice downstream from the fluid inlet, the dosing head further defining a high pressure port through the sidewall upstream from the internal orifice to intercept a portion of flowing liquid from the fluid inlet;
• a dosing cap disposed over the sidewall of the dosing head, the dosing cap defining a mixing chamber in downstream fluid communication with the internal orifice, the dosing cap defining a low pressure port in fluid communication between the high pressure port and the mixing chamber;
• and
• a treatment enclosure defining a solute chamber housing a dosed media therein, the treatment enclosure being positioned in downstream fluid communication with the high pressure port to receive the liquid intercepted through the high pressure port, the treatment enclosure being further positioned in upstream fluid communication with the low pressure port to deliver the treating solution.

A passive fluid dosing system comprising:

• a dispensing head defining a water nozzle;
• a water supply conduit disposed in fluid communication with the dispensing head at a location upstream from the water nozzle;
• a passive dosing body disposed between the water supply conduit and the dispensing head, the passive dosing body defining
• a primary flow path extending from the water supply conduit to the dispensing head,
• a liquid treatment path bypassing a portion of the primary flow path,
• a high pressure port positioned along the liquid treatment path downstream from the water supply conduit,
• a low pressure port positioned along the liquid treatment path downstream from the high pressure port and upstream from the dispensing head, and
• a mixing chamber in fluid communication with the supply conduit downstream from the low pressure port;
• a pressure plate disposed within the passive dosing body between the high pressure port and the low pressure port, the pressure plate defining an internal orifice to decrease liquid pressure downstream from the pressure plate;
• and
• a treatment enclosure positioned in fluid communication between the high pressure port and the low pressure port along the liquid treatment path, the treatment enclosure defining a solute chamber housing a dosed media to generate a treating solution delivered to the primary flow path through the low pressure port,
• wherein the passive dosing body comprises a dosing head and a dosing cap, wherein the dosing head comprises a sidewall defining the high pressure port, wherein the dosing cap is disposed over the sidewall of the dosing head, and wherein the dosing cap defines the mixing chamber and the low pressure port.
