Festo wastewater technology
in Prague Zoo
The new elephant and hippo pavilion at Prague Zoo
has clean water and added safety thanks to pneu-
matic components from Festo. While visitors get to
enjoy a clear underwater view of the pachyderms
through a glass wall, behind the scenes a purifica-
tion system is hard at work removing fibres and
turbidity. Festo was chosen to supply the pneumatic
components on the basis of the company’s experi-
ence in wastewater treatment and the extensive
product range, including ready-to-install complete
solutions.
The actuators and valves are located in a total of
four machine rooms. By using pneumatic rather than
electric actuators, valves and sensors can be ope
rated at a safe voltage of 24 V DC. The absence of
high voltage in a damp environment means greater
safety for both people and animals.
