As water passes through the treatment chamber, ultraviolet light inactivates susceptible microorganisms. Proper selection, installation and maintenance matter: performance depends on the model, water conditions and flow through the system.
What UV can address
UV can help address bacteria and certain other waterborne pathogens without adding disinfecting chemicals. Match the equipment to the organisms and treatment conditions covered by its manufacturer documentation.
What needs other treatment
UV does not remove PFAS, lead, hardness or dissolved chemicals. Separate treatment may be needed for those concerns. Sediment and other water conditions can also interfere with UV performance.
For private well owners, changing water quality makes appropriate laboratory testing especially valuable. A clear glass of water is no substitute for a test. The CDC’s home water treatment guide explains why treatment should match the contaminants in your water.
Designed with the homeowner in mind
Simpler lamp replacement
The combined lamp-and-quartz-sleeve unit uses a single connection, simplifying handling during replacement.
Helpful touchscreen controls
An LCD touchscreen displays system information and lamp replacement reminders, helping you keep track of routine care.
Flexible mounting
The chamber can mount vertically or horizontally. VIQUA prefers vertical mounting; either arrangement must follow the model’s installation instructions.
Aligned plumbing connections
The Tidal chamber places the inlet and outlet on the same plane to simplify piping connections.
Built-in UV shielding
PolyProtect shielding allows direct connection to PEX and other compatible plastic plumbing as specified by VIQUA.
Options for different homes
Multiple system sizes and Arros IHS configurations with integrated prefiltration help match the equipment to your home.

Good equipment deserves the right fit
Before choosing a model, work through these points with the Aqua Science team:
- Start with your water test. Share current laboratory results and any changes in your water source or quality.
- Review household demand. Discuss the flow your home needs and your existing treatment equipment so the system can be sized appropriately.
- Plan water preparation. Check the manufacturer’s water-quality requirements. Sediment filtration or other pretreatment may be needed before UV.
- Plan ongoing care. Follow the manufacturer’s schedule for lamp replacement, cleaning and filter maintenance. Keep the model number handy when ordering parts.
