The PURA portfolio reflects the practical application of an innovative and sustainable technology for the biological treatment of pool water. Each project represents the integration of a patented solution, developed to ensure superior water quality without the use of chemicals, with reduced energy consumption and minimal environmental impact. With installations implemented in residential and tourist contexts, the PURA system adapts to different types and sizes, whether in new constructions or renovation processes. The versatility of the solution allows it to effectively meet technical, aesthetic, and environmental demands, while always maintaining water stability and user comfort. The presented projects demonstrate not only the technology’s reliability but also the commitment to health, efficiency, and sustainability. This portfolio is the reflection of a concept that combines engineering, ecology, and design in service of a new generation of swimming pools.
