Case Study from HydroFLOW Ukraine
Wave pool chlorine reduction and water clarity
Wave pool chlorine reduction was needed at a 620 cubic metre wave pool in Ukraine that was regenerating its filters frequently and dosing chlorine heavily. Even so, biofilm was forming on the water surface and organic particles were clouding the water, under the high bather load a wave pool carries. In June 2018 one HydroFLOW® unit was fitted before the circulation pump and sand filters, with the pool open. Filtration improved, the surface biofilm stopped forming, and the water was clear within 12 days. Chlorine use came down by 60%, and clarity was maintained under high bather load.
The Challenges
- Wave pool chlorine reduction was needed, with high dosing in use
- Frequent filter regeneration was required
- Biofilm was forming on the water surface
- Organic particles were reducing clarity
- The pool carries a high bather load
The Solution
- Unit installed: one HydroFLOW® unit
- Installation point: suction side of the circulation pump, before the sand filters
- Installed: June 2018, with the pool open
- System: 620 m³ wave pool
The unit went on the suction side of the circulation pump while the pool stayed open, so the improvement was measured under normal bather load rather than in a quiet period. The signal improves filtration and disrupts the conditions that let biofilm form. The operators reduced chlorine dosing step by step as the water tests allowed, and the wave pool chlorine reduction reached 60%.
