Prague Zoo has been struggling with poor water in reservoirs since the beginning of the construction of pavilion for hippopotamus. Visitors search in vain for bathing hippo families in vortexed muddy water, full of straw. Poor water filtration technology is to blame. And therefore in the autumn of last year a public contract for the reconstruction of pool water treatment system in the hippo pavilion was announced.
This year Moravia Systems has already supplied 20 pieces of knife gate valves with pneumatic operating and 34 pieces of SIGEVAL butterfly valves with double-acting pneumatic actuators and electropneumatic positioners for this order.
