Maximize Water Quality Without Chemicals

UV disinfection systems offer an affordable way to protect against bacteria, parasites, and other disease-causing microorganisms. Removing dissolved substances such as hardness minerals, iron, manganese, and tannin while reducing turbidity and color will improve UV disinfection performance, protect equipment, and ensure production of safe, high quality water. SmartStream UV can be configured with other Watts water quality technologies to create complete water treatment system, making it a sensible solution to ensure the highest quality of water disinfection.
