ABOUT THE CLIENT
MOBILE SWIMMING POOL CONTAINER IN GERMANY
The Josef Wund Stiftung gGmbH foundation initiated the “Wundine on Wheels” project to address the growing need for accessible swimming facilities across Germany.
The project focuses on providing Learn-to-Swim pools in regions where local access to pools is limited, offering kindergarteners and school-aged children the opportunity to learn essential swimming skills.
To achieve this, the foundation developed an innovative solution: a mobile swimming pool container that can be transported between municipalities, ensuring swimming education reaches children in remote areas.
WHAT THE CLIENT NEEDED
A COMPACT SECONDARY DISINFECTION SYSTEM
To support the goals of Wundine on Wheels, the client required a robust secondary disinfection system that would meet the high public health standards for swimming pools, provide reliable chloramine reduction, and fit within a compact mobile container.
While activated carbon filtration is commonly used in Germany for similar applications, this particular mobile setup presented a key logistical challenge. Movement of the container could disrupt the activated carbon filter, damaging the carbon while forcing costly, time-intensive replacements or reactivation once the container reaches a new destination. Additionally, there is the limited effectiveness of activated carbon filtration in terms of managing chlorine-resistant pathogens.
To overcome these challenges, alternatives had to be explored beyond carbon filtration, which led to focus on UV technology due to the compact footprint, efficiency in chloramine reduction, as well as ease of maintenance.
THE SOLUTION
RELIABLE CHLORAMINE REDUCTION
After evaluating various options, the client selected the PoolRay MP1-600 – a compact, medium-pressure UV disinfection system specifically designed to control chloramine levels while maintaining a minimal physical footprint within the container.
The solutions offer several benefits, including effective control of chloramine buildup, minimizing unpleasant odors and eye irritation while also reducing the health risks associated with chlorine byproducts. The system is designed to support a 12 m³/hour flow rate, which is essential for the 6×2 m² training pools operated in each mobile unit. To ensure optimal flow around the UV lamp, the pipe diameter was increased from D63 to D110.
Moreover, the UV system eliminates the need for activated carbon, which avoids the costly replacement of carbon filters at each setup. This innovation streamlines the setup process and allows the mobile swimming pools to be operational within 36 hours, making it feasible to transport and prepare units across various locations without substantial downtime.
Through this containerized POOLRAY UV solution, ULTRAAQUA has effectively contributed to creating a safe, efficient, and mobile swimming education program. So far, a total of 4 mobile swimming containers are planned to be set on wheels, with the first three already in operation, bringing essential swim safety training to communities across Germany.
