| Devices such as micro-bubble separators, pressure step degassers, automatic air vents etc. cannot prevent corrosion. The oxygen in the air bubbles reacts very quickly with the steel it comes into contact with.This happens faster than the separators can expell the air. If the expelled ´air´is analysed it is found to be mainly consisting of nitrogen. | Devices such as micro-bubble separators, pressure step degassers, automatic air vents etc. cannot prevent corrosion.

| The condition of the fill and system water can have a marked effect on the corrosion potential. Water is a cheap and plentiful medium and is, therefore, the preferred liquid. Water isn't just water and water chemistry is very complex. It can be highly corrosive to steel and other metals if certain values such as pH and conductivity are unfavourable. | The condition of the fill and system water can have a marked effect on the corrosion potential.
