Anyone who owns an aquarium knows how difficult it is to maintain water quality at a  consistently high level. The principle “The larger the tank, the more  stable the water values” depends on the number and size of its inhabitants. When they are dolphins, like at Nuremberg Zoo the water treatment requirements are particularly challenging.

Cleaner than any swimming pool “The water in the Nuremberg Zoo dolphin lagoon is cleaner than that of any swimming pool,” says Klaus Held from engineering firm Sixt, Heiß & Partner, a specialist in complex water treatment installations. “Saltwater poses much greater challenges than the chlorinated fresh water used in swimming pools in terms of the durability and corrosion resistance of process valves and actuators,” explains Held.
