Typically, activated carbon filters are used in food and beverage production to remove unwanted substances such as chlorine, heavy metals or other components. IMEX Filtertechnika Kft has been providing the necessary brewing water purity in a large Hungarian brewery with two high-quality activated carbon filter stations since the winter of 2020. Both units with a flow rate of 60 m³/h each are completely made of AISI316L stainless steel to withstand hot water disinfection utilized to reduce the risk of microbiological contamination.
The operating principle for guaranteed water purity:
At the inlet of each IMEX activated carbon filter system there is a pneumatic membrane valve with an integrated positioner. This positioner controls the flow rate across each filter housing, ensuring an optimum filtration rate across the activated carbon bed.
Each filter container has a pressure sensor both at the inlet and at the outlet. The system continuously measures the pressure drop via these sensors. As soon as a predefined value is exceeded, the backwash process starts automatically.
The complete skid can be sanitized automatically up to 85 °C with hot water. For this purpose, the inlet and outlet valves are closed but the hot water supply and the drain valve are opened instead. A temperature sensor in the system monitors the supply of hot water to ensure 85 °C throughout the system.
The process is controlled by fixed intervals, but can also be triggered manually at any time.
