Siemens Water Technologies Co-stars in 4th Harry Potter Film
"The lake was an important setting in this movie," says Barry Humphries, sales manager of Siemens Water Technologies. "So the water needed to be absolutely crystal-clear for the extensive underwater scenes. The actors were extremely happy with the water quality."
The UV Astron units inactivated any microorganisms in the pool water, ensuring the water was safe for the actors who spent considerable time in the set-designed lake. Dosing the lake with EzeFloc Aktiv then kept the water clear by quickly forming a highly active floc that bound the resulting suspended solids and prevented them from passing through the filter bed. Finally, the Ezetrol controller measured chlorine and pH levels to comply with specific disinfection parameter set points. This combination was important for the film crew, as it helped to provide a water quality suitable for long periods of underwater filming and time spent with the actors in the pool.
