The Challenge
- Hot water pipework biofouling had built up across both new and decades-old sections
- Thick biofouling deposits altered water quality
- Rust layers and flakes accumulated inside the pipework
- Scale was also present inside the water-supply pipes
- The building runs nine levels above ground, nine below and more than 1,000 rooms
The Solution
One HydroFLOW® i120 was fitted to Palace of Parliment in Bucharest on the 120 mm pump-free hot-water supply line, and a newer galvanised pipe section was visually assessed against adjacent steel pipework that had been in service for more than 30 years, over six months. Visual inspection estimated about 50% less biofouling across both sections. The newer pipe was protected from further biofouling and showed no further calcium or magnesium salt deposition, while existing deposits inside the decades-old pipe visibly reduced.
