Water treatment in swimming pools reduction of electricity consumption

Measurements were made in five swimming baths, and energy savings were achieved using new filters, pumps, water treatment control depending on bather load, etc. In a 50 metre pool, electricity consumption for water treatment fell by 50%, and in a hot-water/paddling pool, electricity consumption fell by 30-40% while still maintaining satisfactory water quality – even during periods of heavy bather load. In another swimming bath, ventilation electricity consumption was reduced by 15%. The results will e.g. be used to revise the executive order on swimming pools and water quality to allow bather load-dependent water circulation. (Energy 10)
