AERZEN Technology at the L‘Aquarium in Barcelona

The spectacular Oceanario de L’Aquarium in Barcelona is considered the largest and most species-rich aquarium in Europe. With a diameter of 36 metres and a depth of 5 metres, it holds approximately 4 million litres of water. A few months ago, an AERZEN Delta Blower package was put into operation in the L’Aquarium. A large team of highly qualified professionals and cutting-edge technology enables to guarantee the health and wellbeing of over 11,000 animals at the L’Aquarium.

Around 6 million litres of seawater is needed to fill the 21 aquariums. This water is supplied continuously by means of controlled extraction in wells arranged specifically for this purpose. A sophisticated water purification system enables operation in a semi-closed cycle. Purification and filtration are required for a number of reasons. When leftover food, along with the excrement of each organism (with a high ammonium content), is biologically degraded, secondary chemical compounds form (nitrites and nitrates), which are very harmful to the occupants of the aquarium and must be removed. Final sterilisation of the water is required as a biological prevention measure towards the exterior of L’Aquarium.

The new AERZEN Delta Blower starts up in case of emergency, such as an electrical breakdown, and thus makes sure that the water runs out of filtration, and the fishes are provided with oxygen. The circulation of water is what generates oxygen. In addition, in an emergency, porous, pumice-like stones are put in the water to oxygenate the water. The AERZEN Delta Blower provides absolutely oil-free air according to ISO class. For the Aquarium application, it is a must: If the blower was operated with oil it would be fatal for the fishes.
