Selection of a water deoxygenation method presents some challenges due to the broad range of options including physical, chemical, electrochemical and biological techniques. This communication presents the design of an apparatus developed for efficient and simple deoxygenation of water for the purpose of electrochemical corrosion studies in a lab environment. The design is modular and can be scaled to meet processing needs. The operation of the apparatus is based on the combination of nitrogen bubbling and surface absorption to achieve complete and uncontaminated deoxygenation of water. Tests conducted on this apparatus revealed that pressurisation of the apparatus enhances economy and performance while increasing nitrogen injection rate accelerates deoxygenation. However, a point was identified, at which a balance between economy and performance is achieved and further injection rate increase suffers from diminishing returns.
