Abstract

A system for removing a gas from a liquid comprises an aeration tank for aerating a raw liquid containing a gas to remove the gas by causing an agitated air flow through the liquid. A plurality of aeration plates placed substantially horizontally across the horizontal cross sectional plane of the tank, the aeriation plates perforated by a plurality of openings. Aerating the liquid occurs with the liquid flowing downward into the aeration tank, and an airflow flowing upward through the liquid from a point proximate to the bottom of the aeriation tank, wherein the aeriation plates are configured to impart a crisscross movement pattern in the liquid flow down and the airflow up as each passes the other to agitate and mix the flow of liquid and air.

Claims

1. A system to remove a gas from a liquid, the system comprising:

an aerating tank aerating a liquid containing a gas to remove the gas by causing an air flow through the liquid and temporarily storing the aerated liquid prior to being delivered into a liquid distribution system;

wherein aerating the liquid uses a liquid flow flowing downward into the aerating tank, and an air flow upward through the liquid in the aerating tank, with the liquid flow and the airflow having a crisscross movement pattern past each other.

2. The system of claim 1, further comprising:

a liquid input valve configured to control the flow of the liquid into the system;

a purely mechanical, differential float system configured to control the liquid input valve.

3. The system of claim 2, wherein the differential float system comprises a float configured to move or slide up or down a line depending on level of liquid between an upper stop and a lower stop, wherein the differential float system operates to open the valve when the float contacts the lower stop and operates to close the valve when the float contacts the upper stop.

4. The system of claim 3, wherein the positions of the stops along the line are adjustable.

5. The system of claim 1, wherein the aerating tank is configured so liquid and air flow in opposite directions through a plurality of perforated aeration plates, arranged horizontally in the aerating tank, having openings or passages configured to agitate the liquid and air to mix the liquid and air by imposing the crisscross pattern of movement to the liquid and air.

6. The system of claim 1, wherein the aerating tank comprises an easy-to-open, pry-off lid with substantially unobstructed access for easy maintenance.

7. The system of claim 1, further comprising a second storage tank for storing aerated water with gas substantially removed.

8. The system of claim 8, further comprising:

a liquid input valve configured to control the flow of the liquid into the system;

a purely mechanical, differential float system inside the second storage tank configured to control the liquid input valve.

9. A system removing a gas from a liquid, the system comprising:

an aeration tank for aerating a raw liquid containing a gas to remove the gas by causing an agitated air flow through the liquid;

a plurality of aeration plates placed substantially horizontally across the horizontal cross sectional plane of the tank, the aeriation plates perforated by a plurality of openings;

wherein aerating the liquid occurs with the liquid flowing downward into the aeration tank, and the air flow flowing upward through the liquid from a point proximate to the bottom of the aeriation tank, wherein the aeriation plates are configured to impart a crisscross movement pattern in the liquid flow down and the airflow up as each passes the other to agitate and mix the flow of liquid and air.

10. The system of claim 9, further comprising:

a raw liquid input valve configured to control the flow of the raw liquid into the system; and

a purely mechanical, differential float system inside the tank configured to control the raw liquid input valve.

11. The system of claim 10, wherein the differential float system comprises a float configured to move or slide up or down a line depending on level of liquid in the tank between an upper stop and a lower stop, wherein the differential float system operates to open the valve when the float contacts the lower stop and operates to close the valve when the float contacts the upper stop.

12. The system of claim 11, wherein the positions of the stops along the line are adjustable.

13. The system of claim 9, wherein the tank comprises an easy-to-open, pry-off lid with substantially unobstructed access for easy maintenance.

14. The system of claim 9, wherein the liquid comprises water and the gas comprises radon.

15. A method removing a gas from a liquid, the method comprising the steps of:

aerating a liquid containing a gas to remove the gas by causing an agitated air flow through the liquid in an aeration tank;

using a plurality of aeration plates placed substantially horizontally across the horizontal cross sectional plane of the tank to aerate the liquid, the aeriation plates perforated by a plurality of openings;

flowing the liquid downward in the aeration tank;

flowing the air upward through the liquid in the aeriation tank;

wherein the aeriation plates are configured to impart a crisscross movement pattern in the liquid flow down and the airflow up as each passes the other to agitate and mix the flow of liquid and air; and

venting extracted gas out of the aeration tank.
