Water Treatment Planning and Consulting
Comprehensive water treatment planning for clean pool water
Modern, intelligent, and properly functioning water treatment design significantly reduces system operating costs, maintenance costs, and energy costs. It also simplifies the water treatment process and the monitoring of pool water quality.
Sweco is Finland’s leading expert in water treatment design for swimming pool water. We offer comprehensive expertise for buildings and properties that include swimming pools, managing the challenging conditions of pool environments, and designing, implementing, and monitoring systems.
Water treatment consulting for municipalities and private sector
Our clients include cities and municipalities that need to renew or repair existing municipal swimming pool and spa water treatment technology or build entirely new swimming pools. We also undertake projects for the private sector, such as hotels, spas, residental care homes, and similar facilities requiring specialized water treatment technology. If necessary, we assess the functionality and condition of the client’s existing water treatment system and evaluate, for example, the need for repairs, circle of life, and energy efficiency.
Ensuring clean and properly heated pool water
The swimming pool user only sees a pool full of clear water, but behind the scenes, a carefully designed and implemented water treatment design ensures safe swimming water. Pool water is measured, monitored, purified, and adjusted every single second. The water in a standard 25-meter swimming pool is completely renewed on average every five hours, and the water in a hot tub even every three minutes.
Swimming pool water circulation process and ventilation
The swimming pool water circulation process consists of several different treatment stages and devices. Water is usually led from the pool through overflow channels to a balancing tank, from which it is pumped for treatment. The treatment includes coarse filtration, coagulant dosing, fine filtration, UV treatment, heating, pH adjustment, and disinfection.
Proper and adequately designed ventilation is also essential for managing the quality of pool water and indoor air. Our experts ensure that the ventilation at the pool water surface level is sufficient and the pressure relationships in the spaces are correct.
