Aertube: A Comprehensive Look at Static Tube Aeration

Aertube, synonymous with static tube aerators, represents a vital technology in environmental engineering. These devices are specifically designed to enhance oxygen transfer into water, playing a crucial role in water treatment and wastewater management.

How Aertube Works:

1. Air Injection: Air is forced into the Aertube through a dedicated blower system, creating pressure within the device.
2. Diffusion: The air, under pressure, passes through meticulously engineered perforations in the Aertube. These perforations are designed to maximize the surface area of contact between air and water, creating a large number of tiny air bubbles.
3. Oxygen Transfer: The small bubbles rise through the water, increasing the contact area between the air and the water. This facilitates the transfer of oxygen from the air bubbles into the surrounding water, increasing the dissolved oxygen (DO) levels.

Types of Aertube:

1. Fine Bubble Aertube: Utilizes smaller perforations, creating a higher density of fine bubbles, enhancing oxygen transfer efficiency.
2. Coarse Bubble Aertube: Features larger perforations, creating larger bubbles with a lower density, suitable for larger water volumes.
