Abstract

There is disclosed a liquid processing system that diffuses gas into a flow of liquid. The system comprising: a diffusion chamber through which a flow of a liquid occurs, further including a gas exchange membrane arrangement that is in fluidic communication with the flow of liquid; a gas reservoir coupled via an inlet of a gas plenum to the gas exchange membrane arrangement to supply gas; a liquid container coupled to the diffusion chamber via a liquid inlet to supply a flow of liquid. The system comprises a pressure control device coupled between the gas reservoir and the gas inlet. The pressure control device includes first and second gas flow paths arranged fluidically in parallel. The first path limits a pressure drop to a maximum threshold pressure. The second path is a bleed flow path having a resistance to a gas flow therethrough. The pressure control device, when in operation, limits a pressure of gas within the gas plenum lower than pressure of the flow of liquid at temporal commencement and cessation. The pressure of the flow of liquid above pressure of gas within plenum is limited to within a maximum differential pressure.
