Secondary disinfection using UV and ozone in public swimming pools
Efficient secondary disinfection with modern systems
In advanced water treatment, a second stage of disinfection is often added to the standard chlorine process. Modern UV or ozone systems minimise by-products, are easy to install, improve water quality and cut operating costs.
Requirements - Secondary disinfection using UV and ozone in public swimming pools
Overview
Cut consumption – but maintain effectiveness
ProMinent has become a specialist in efficient and easy-to-install UV and ozone systems, reliably serving customers the world over. In difficult conditions, such as when there are high levels of urea and germs, using ozone systems can increase disinfection protection and minimise use of chlorine as the disinfectant. They are prescribed according to DIN 19643 as an additional means of disinfection for hydrotherapy pools in Germany, provided that there is no ultrafiltration in the water treatment.
Advantages of ozone disinfection
Ozone-based disinfection offers numerous benefits: No unwanted by-products are produced, the smell typically associated with swimming pools doesn't arise and there is no need to meter flocculants. Circulation capacity, the supply of fresh water and chemical consumption are all reduced, cutting operating costs.
Advantages of UV disinfection
UV systems are a cost-effective way of reliably breaking down chloramines and safely killing off chlorine-resistant germs. The result is vastly improved water quality. Other plus points, all of which help to reduce operating costs, include the minimal space requirement, suitability for retrofitting and the fact that operation requires virtually no maintenance.
