Crystal Lagoons’ technology applies an efficient filtration system that uses only 2 percent of the energy consumed by conventional swimming pool centralized filtration systems. Crystal Lagoons’ patented solution is to apply additives and different ultrasonic waves to the water in the lagoon, which enable the contaminant particles to be agglomerated into larger particles that are later removed from the lagoon. This means that only a small portion of the total water volume needs to be filtered. Also, as the filtered flow is up to 300 times lower than for conventional systems, the whole filtration system is smaller, decreasing installation requirements in terms of pumps and filter sizes.
