D1’s patented UltraPure® system builds upon the ClearZone® system. UltraPure® is more than just an ozone generator; it’s a fully engineered water management system similar to the systems used throughout European municipal waste facilities. It has a dedicated filtration and water purification system, processing about 10,000 gallons a day. After filtering the water, this system vigorously mixes ozone and water three times to ensure ozone comes in contact with every drop of water – ozone doesn’t just kill bacteria, it burns it up! That means the water is not just clean, it’s crystal clear.
