Abstract
A cost-effective system and method dissolves gas, such as oxygen, into water in a manner that prevents gas bubble carry over by using a bubble capture system (BCS). The method further eliminates or minimizes turbulence at the suction and discharge of a pump using an energy dissipation header (EDH). The BCS can create a top-down flow that permits bubbles to rise faster than the velocity of the downward flow of water. The EDH can use a pipe design, such as a slotted pipe design, that permits a maximum system water flow. The technology can be applied to water bodies to mitigate eutrophication and may also be applicable in other fields, such as wastewater lift stations, fish farms, oil and gas industry, tidal applications with low flushing rates, and winter under ice oxygenation to prevent fish kills.
Claims20
A water treatment system for treating a body of water, comprising:
- an intake header having a plurality of openings, permitting a predetermined maximum flow of water through the intake head;
- a discharge header having a plurality of openings permitting an outflow predetermined maximum flow of water through the discharge header;
- a pump drawing water from a water body through the intake header;
- an oxygen contact chamber operable to oxygenate water flowing therethrough, the pump delivering water into the oxygen contact chamber, wherein the oxygen contact chamber has a conical shape;
- and
- a bubble capture system (BCS) receiving water from the oxygen contact chamber at an upper end thereof inside a housing, outflow being release from the BCS at a lower end of the housing, wherein:
- the housing comprises a riser;
- the pump, the oxygen contact chamber and the BCS are disposed in the body of water;
- and
- the bubble capture system and the riser minimize, prevent or eliminate gas bubbles in the outflow delivered back to the body of water via the discharge header.
A water treatment system for treating a body of water, comprising:
- an intake header having a plurality of openings, permitting a predetermined maximum flow of water through the intake head;
- a discharge header having a plurality of openings permitting an outflow predetermined maximum flow of water through the discharger header;
- a pump drawing water from a water body through the intake header;
- an oxygen contact chamber operable to oxygenate water flowing therethrough, the pump delivering water into the oxygen contact chamber, wherein the oxygen contact chamber has a conical shape;
- and
- a bubble capture system (BCS) receiving water from the oxygen contact chamber at an upper end thereof inside a housing, outflow released from the BCS at a lower end of the housing and passed through the discharge header back to the water body, wherein:
- the housing comprises a riser;
- the predetermined maximum flow is either equal to or less than about 0.1 feet per second or the predetermined maximum flow results in a flow with a Reynolds number less than 50;
- the pump, the oxygen contact chamber and the BCS are disposed in the body of water at a water level where the intake header and the discharger header are located;
- and
- the bubble capture system and the riser minimize, prevent or eliminate gas bubbles in the outflow delivered back to the body of water via the discharge header.
