The CUV Series Ultraviolet Clarifiers (UVC) are an important part of any filtration system. In the clarification process, water is passed through the UVC chamber and the UVC bulb flocculates (clumps) the microscopic green algae, that are suspended in the water. The flocculated algae can then be captured by a mechanical filter. To ensure clear water the UVC must be properly sized for the filtration system and the correct flow rate must be maintained through the UVC.
As a component of the Clearwater Guarantee the CUV-18 and CUV-36 Ultraviolet Clarifiers along with a properly sized filter and filtration pump will guarantee that the pond or water garden will have clear water for a lifetime.
