How Does an Air Injection Dissolved Iron Filter Work?

An air injection dissolved iron filter effectively removes iron and other contaminants from water through a multi-step process involving air injection and oxidation.

• Air Injection: The process begins with the injection of air into the water, which creates a turbulent mixing environment.
• Oxidation: The dissolved iron in the water oxidizes when it comes into contact with the air, converting it from soluble ferrous iron to insoluble ferric iron.
• Filtration: The oxidized ferric iron forms small particles that can be easily filtered out by the media within the filter.
• Backwashing: Periodically, the system undergoes backwashing to remove accumulated iron particles and ensure optimal performance of the filter media.

Air injection introduces oxygen into the water, which is essential for the oxidation process. This step is critical because it increases the efficiency of the filter by ensuring that the dissolved iron is transformed before reaching the filtration stage.

During oxidation, the soluble ferrous iron (Fe2+) reacts with the oxygen to form ferric iron (Fe3+), which is not soluble in water. This transformation is vital as it makes it possible for the iron to be removed from the water through the subsequent filtration process.

In the filtration stage, the newly formed ferric iron particles are trapped by the filter media, which typically consists of sand, anthracite, or other granular materials designed to capture these particles effectively. This ensures that the water produced from the system is free from iron and other contaminants.

The backwashing process is essential for maintaining the filter’s efficiency. During backwashing, water is pumped in the reverse direction through the filter media, dislodging and flushing away the accumulated iron particles, thereby rejuvenating the filter for continued use.
