The Hot Water Deaeration (HWD) deaerates water down to a residual oxygen concentration below 10 ppb. At the same time the water is pasteurized. Optionally it can be cooled down, filtered or pre-carbonised. 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, high heat recuperation up to 95% and low consumption. Microbiological safety is ensured by the simultaneous pasteurization of the water.
