Air filtering for Drinking Water Storage Tanks

Q: "What sizes of aeration\/deaeration systems does HUBER SE offer?"

"HUBER offers a total of four different sizes of aeration\/deaeration plants.\r\nBLA L251, BLA L252, BLA L361 and BLA L661. These air filter plants differ mainly in their throughput capacity and size and range from 250 m\u00b3\/h to 3000 m\u00b3\/h."

Q: "Which component should not be omitted when planning a drinking water reservoir?"

"When building a drinking water reservoir, you should never do without an aeration and deaeration system.\r\nThe aeration and deaeration of drinking water reservoirs is necessary for pressure equalisation as the water level in the water chamber varies. The air streaming into the reservoir must be filtered sufficiently to ensure it is free of dust, pollen and other pollutants."

Q: "Which standards do the filters used in an aeration\/deaeration plant comply with?"

"The air filters installed in HUBER aeration\/deaeration plants comply with the current standards EN ISO 16890 and DIN EN 1822."

Q: "How can forced ventilation be implemented?"

"If there are no water level fluctuations in the drinking water reservoir and therefore no natural air exchange can take place, we can optionally work with a fan in the air duct. This ensures an optimal air exchange in the reservoir."

Q: "What happens to the aeration\/deaeration plant in the event of an accident in the drinking water reservoir?"

"A safety valve can be optionally installed for such a case. This opens in the event of an emergency and thus prevents damage to the air filter system."

Filtering the supply air reduces hygiene hazards

Every drinking water reservoir respirates: Aeration and deaeration of drinking water reservoirs is necessary for pressure equalisation as the water level in the water chamber varies. Huge amounts of air are sucked in as drinking water is being withdrawn. This air must be pressed out again during tank filling. The hygiene problem lies in the “breath-in” process. Depending on ambient air quality, there is a certain risk that higher amounts of dust, bacteria, viruses and germs may pass into the stored drinking water.

Ventilation technology with HUBER air filter plants reliably prevents such risks. Generally, only filtered ambient air should be allowed to pass into the water reservoir.
