Plumbing Guide

Aeration exposes well water to air, which oxidizes iron and sulfur gases and lets them be filtered out. It is the classic treatment for sulfur smells and iron that a softener alone cannot handle.

Aeration Water Treatment: A Chesterfield Guide

The process

Aeration injects air into the water or sprays the water through air, and the oxygen reacts with iron and sulfur. The oxidized particles then settle or filter out.

The iron

Iron that is dissolved and clear turns into rust-colored particles when oxidized, and a filter removes them. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Chesterfield, wells with iron benefit from aeration.

The sulfur

Hydrogen sulfide gas is driven off by aeration, so the rotten-egg smell disappears before the water reaches the tap.

The system

An aerator, a contact tank, and a filter work together, and the setup is sized to the water's flow and the contaminant level.

The maintenance

The filter media and the aerator are serviced on a schedule, and the media is replaced when spent.
