The Vacuum Water Degassing (VWD) deaerates water down to a residual oxygen concentration below 10 ppb. 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 employed in the brewing, beverage, food and chemical-pharmaceutical industries, wherever water with lowest oxygen content is required to assure high product quality and stability. The system is characterized by high operational reliability, low CO2 and energy consumption.
