Abstract

Systems, apparatus and methods are described that control and manage water collection and treatment. One or more sensors monitor and measure levels of contaminants, other chemicals and or environmental conditions in a well of a tank, well and/or collection station and/or in inflow and/or outflow mains. An additive that can include one or more of ozone, oxygen, a bioagent, bleach, peroxide and other chemicals, and selected to treat chemicals and/or contaminants in water, can be mixed with water in the well and the main. An infusion assembly deployed within the tank is adapted to mix the water and additive into a body of water in the well. A processor configured to control the rate at which the additive is provided to the infusion assembly or force main based on measurements of contaminants received from the first and second sensors.

Claims

1. A water treatment system comprising:

a collection station having a tank for collecting a body of water received from an inflow main;

an infusion system that receives a portion of collected water from the body of water, the infusion system comprising a hydrodynamic mixing chamber, wherein an additive is mixed with the portion of collected water before the portion of collected water mixed with the additive is reintroduced to tank; and

a controller comprising one or more processors configured to monitor the level of water in the well, and configured to maintain the level of water in the tank within predetermined limits by causing one or more pumps to provide an inflow and an outflow of water, wherein

the controller is further configured to control a rate of flow of the additive to the mixing chamber.

2. The water treatment system of claim 1, wherein the infusion system comprises a manifold that conducts the portion of collected water and the additive to the mixing chamber.

3. The water treatment system of claim 1, wherein the controller controls the rate of flow of the additive based on measurements of one or more chemicals.

4. The water treatment system of claim 1, wherein the additive comprises oxygen.

9. The water treatment system of claim 1, wherein the controller is configured to control a main treatment system, wherein the main treatment system mixes oxygen with water in one or more of an inflow main and an outflow main.

10. The water treatment system of claim 9, wherein the controller controls rate and frequency of treatment of the water in the one or more mains based on a measurement of oxygen in the one or more mains.

11. The water treatment system of claim 9, wherein the controller controls rate and frequency of treatment of the water in the one or more mains based on a measurement of residual oxygen in the one or more mains.

12. The water treatment system of claim 9, wherein the controller controls rate and frequency of treatment of the water in the one or more mains based on a measurement of water flow in the one or more mains.

13. The water treatment system of claim 9, wherein one or more of the inflow main and the outflow main comprises a force main.

14. The water treatment system of claim 9 wherein the controller controls rate and frequency of treatment of the water in the one or more mains based on a measurement of contaminants measured in the well.

5. The water treatment system of claim 5, wherein the measurements include a measurement of oxygen in the collected water.

6. The water treatment system of claim 5, wherein the measurements include a measurement of oxygen in an outflow main.

7. The water treatment system of claim 5, wherein the measurements include a measurement of oxygen in an inflow main.

8. The water treatment system of claim 5, wherein the measurements include a measurement of carbon dioxide in the well.

15. A water treatment method comprising the steps of:

measuring a concentration of one or more chemicals in a collection tank, the collection tank maintaining a body of water received from an inflow main;

providing a portion of the water to an infusion system comprising a hydrodynamic mixing chamber and a nozzle;

controlling flow of an additive to the mixing chamber, wherein the additive is selected to neutralize the one or more chemicals;

dispersing a mixture of the water and the additive through the nozzle into the body of water; and

evacuating a portion of the body of water through an outflow main.

16. The method of claim 15, wherein the flow of the additive is controlled based on a measured level of a contaminant in the well.

17. The method of claim 16, wherein the additive includes oxygen.

18. The method of claim 16, wherein the additive includes ozone.
