Technical assistance: What is a good deoxidizer for desalinated water?

For offshore oil extraction, deoxygenated seawater needs to be injected into the oil field; the temperature of this seawater is at room temperature. May I ask: what type of deoxidizer is suitable for deoxygenating seawater? Please help and give some advice, thank you!
The traditional deoxidizer, sodium sulfite, performs well at low temperatures and is inexpensive.
Sodium sulfite is the most economical and practical agent for use in seawater; it reacts rapidly at low temperatures and increases the conductivity slightly, but this poses no problem for seawater
Currently, sodium bisulfite is the commonly used option – it offers stable performance at low costs. Other sulfites such as sodium bicarbonate and sodium metabisulfite have similar properties, and this is also true for offshore oil fields.
It doesn’t seem to have been deoxygenated using a deoxidizer. It is vacuum distillation to remove oxygen. Our company has many applications abroad for this, such as the offshore platform design by AKER KVAERNER.
