Swimming pool De Kuilart in Koudum was looking for a cost-efficient way to bring down their bound chlorine levels. With a low-pressure UV system of Van Remmen UV technology they had immediate results: less bound chlorine, lower costs and more comfort for staff.
De Kuilart
Swimming pool De Kuilart is a true swimming paradise at the Frisian lakes. The brand-new pool (2022) has three slides, an extensive toddler pool and a competition pool, making it a popular destination for tourists and residents. In the summer months the swimming pool attracts 1200 visitors per day. A cheerful and bustling whole. But with many people in a pool, it is also a place where bound chlorine is created. ‘We knew that with the arrival of the Dutch Environmental Act the bound chlorine may not exceed 0,6 mg/l. With our brand-new water treatment installation things were already going much better, but on busy days it was difficult to stay below that standard’, says owner Wouter Bleckman.
High costs, high consumption
Bleckman waited a year before purchasing an UV system to find out whether the chlorine levels could also be reduced to less than 0,6 mg/l using only filters. The result was that large quantities of water and chemicals were needed to keep the pool in good condition. ’25 cubic metres per backwash, several times per week. That water is heated from tap water temperature to swimming pool water and provided with sulphuric acid and chlorine to keep the water safe. Altogether, that costs thousands of euros. At the same time, it results in more emissions and a less pleasant air quality. During busy periods, for example, our staff often complained about stinging eyes.’
