The Membrane Water Deaeration (MWD) deaerates water down to a residual oxygen concentration below 10 ppb, using highly efficient hollow fibre membrane modules. Optionally, the water can be cooled down, filtered or sterilized with ultraviolet light. The function of the unit can be monitored and documented by an in-line oxygen analyzer at the outlet of the unit.
The process is used in the brewing, beverage, food and chemical-pharmaceutical industries, wherever water with very low oxygen content is required to ensure high product quality and stability. The system is characterized by high operational reliability as well as low CO2 and energy consumption.
