What does water aeration mean in practice?
Contact with air increases the oxygen content and can remove some of the gases, supporting the oxidation of iron and hydrogen sulfide.
When does it matter?
Injecting air alone does not guarantee a reaction; proper pH, contact time and subsequent separation of the resulting precipitate are needed.
Which solutions are related to it?
An aspirator, compressor or aerator is selected, the tank's venting is secured and a filter capable of retaining oxidation products is installed.
