Aeration

Aeration introduces millions of micro-air bubbles into the effluent through patented tubing, under a flow rate designed to match flow to the treatment unit/s. Oxygen encourages growth of aerobic bacteria which help to digest organics, resulting in further BOD and TSS reductions.

Aeration is the process of increasing oxygen saturation within the water. This happens when the water and air come into contact. This is done by infusing air into the bottom of a lake, lagoon, pond or from surface aeration like a fountain. This allows for oxygen exchange at the surface and the release of gases like carbon dioxide, methane or hydrogen sulfide, which can harm aquatic ecosystems. Low levels of dissolved oxygen can cause fish and other animals harm, while also interring with bacteria, which can help to decompose organic matter within the ecosystem.

Applications:

Promote healthy aquatic ecosystem
Remove carbon dioxide
Improve the decomposition of organic materials
Reduce blue-green algae growth
Reduce phosphorus concentrations to promote algae growth
Oxidation of iron and manganese found in many well waters
Improve oxygen levels in the farm

Types of aeration:
1) Subsurface aeration

Jet aeration
Coarse bubble aeration
Fine bubble aeration

2) Surface aeration

Fountains
Floating surface aerators
Paddle wheel aeration
