Abstract

A passive fluid dosing assembly and system is provided. The passive fluid dosing system may include a passive dosing body, a pressure plate, and a treatment enclosure. The passive dosing body may define a primary flow path and a liquid treatment path. The primary flow path may be defined between a fluid inlet and a fluid outlet. The liquid treatment path may be defined between a high pressure port and a low pressure port, bypassing a portion of the primary flow path. The pressure plate may be disposed within the passive dosing body between the high pressure port and the low pressure port. The pressure plate may define an internal orifice. The treatment enclosure may be positioned in fluid communication between the high pressure port and the low pressure port along the liquid treatment path. The treatment enclosure may define a solute chamber housing a dosed media.

First claim

What is claimed is:

1. A passive fluid dosing system comprising:
a passive dosing body defining a primary flow path and a discrete liquid treatment path, the primary flow path being defined between a fluid inlet and a fluid outlet, the liquid treatment path being defined between a high pressure port and a low pressure port and bypassing a portion of the primary flow path, the high pressure port being positioned downstream from the fluid inlet, and the low pressure port being positioned downstream from the high pressure port and upstream from the fluid outlet;
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 further defines a mixing chamber along the primary flow path downstream from the pressure plate and 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.

2. The passive fluid dosing system of claim 1 , further comprising:
a base plate separating the primary flow path from the solute chamber, wherein the base plate defines a high pressure channel and a low pressure channel along the liquid treatment path, wherein the high pressure channel is positioned in downstream fluid communication with the high pressure port, and wherein the low pressure channel is positioned in upstream fluid communication with the low pressure port.

3. The passive fluid dosing system of claim 2 , further comprising:
a low pressure capillary tube extending through the low pressure channel in fluid communication along the liquid treatment path between the solute chamber and the low pressure port.

4. The passive fluid dosing system of claim 2 , further comprising:
a high pressure capillary tube extending through the high pressure channel in fluid communication along the liquid treatment path between the high pressure port and the solute chamber.

5. The passive fluid dosing system of claim 1 , wherein the dosed media includes a redox agent disposed within solute chamber.

6. The passive fluid dosing system of claim 5 , wherein the redox agent is a chlorine-neutralizing agent or a chloramine-neutralizing agent.

7. The passive fluid dosing system of claim 1 , further comprising:
a secondary filtration media disposed along the primary flow path downstream from the low pressure port.

8. 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.

9. The passive fluid dosing system of claim 8 , wherein the dosing cap includes a base plate separating the mixing chamber from the solute chamber, wherein the base plate defines a high pressure channel and a low pressure channel along the liquid treatment path, wherein the high pressure channel is positioned in downstream fluid communication with the high pressure port, and wherein the low pressure channel is positioned in upstream fluid communication with the low pressure port.

10. The passive fluid dosing system of claim 8 , further comprising:
a low pressure capillary tube extending through the dosing cap in fluid communication between the solute chamber and the low pressure port.

11. The passive fluid dosing system of claim 8 , further comprising:
a high pressure capillary tube extending through the dosing cap in fluid communication between the high pressure port and the solute chamber.

12. The passive fluid dosing system of claim 8 , wherein the dosed media includes a redox agent disposed within solute chamber.

13. The passive fluid dosing system of claim 12 , wherein the redox agent is a chlorine-neutralizing agent or a chloramine-neutralizing agent.

14. The passive fluid dosing system of claim 8 , further comprising:
a secondary filtration media disposed about the dosing cap downstream from the mixing chamber.

15. 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.
