Abstract
A self-uprighting aeration device that minimizes turbulence and disruption of any sediment layer in a tank. The device includes a float positioned about a first position on a longitudinal axis of the aeration device, a ballast positioned about a second position on the longitudinal axis, and a diffuser. The float and the ballast are configured to orient the aeration device in a liquid with the longitudinal axis substantially aligned with a gravitational vector to dispose the diffuser above the sediment layer. The aeration device can be configured to rest on a support surface in the tank or float above such a support surface. Methods for aerating liquid in tanks with the aeration device are also provided.
Claims20
An aeration device defining a longitudinal axis comprising:
- a float positioned about a first position on the longitudinal axis and having an average density;
- a ballast connected to the float, positioned about a second position on the longitudinal axis, and having an average density greater than the average density of the float;
- a diffuser connected to the ballast, and
- a point contact disposed at an end of the longitudinal axis proximal to the ballast and distal to the float,
- wherein the float and the ballast are configured to orient the aeration device in a liquid with the longitudinal axis substantially aligned with a gravitational vector, and
- wherein the diffuser is interfaced with an external air source.
