Commercial UV disinfection
UV as a controlled barrierSelection follows water clarity, flow and installation conditions.
Why commercial UV
UV is a disinfection stage, not another filter.
UV supports microbial control for suitable water and flow inside a controlled chamber.
What it does not do
It does not remove TDS, hardness, dissolved salts, sediment, chlorine, taste or odour.
Why clarity matters
Turbidity and particles can affect performance, so upstream treatment matters.
Downstream hygiene
Storage, pipework and outlets still need appropriate hygiene after UV.
Commercial UV systems
Choose the format, then engineer the stages.
Final selection follows water quality, peak flow and site conditions.

Right-sized filtration + UV recovered 72 sq ft and eliminated RO reject water.
At a Mumbai central kitchen receiving suitable low-TDS municipal water, DhwaNeer replaced a 500 LPH RO plant with Pentair Everpure High Flow CSR + UV900—providing the treatment the application required with a smaller footprint and no reject-water stream.

UV-specific FAQ
What operators want to know.
What does a commercial UV system do?
UV supports microbial control as a disinfection barrier for suitable water and flow. It does not remove TDS, hardness, dissolved salts, sediment, chlorine, taste or odour.
Does UV remove TDS or hardness?
No. UV does not remove TDS, hardness or dissolved salts. RO, softening or another treatment may be considered when those are the actual requirements.
Do I need pre-filtration before UV?
Often, suitable upstream treatment is important because clarity, turbidity and particles can affect UV performance.
How do you size a UV system?
Sizing considers peak flow, clarity and turbidity, UV transmittance when relevant, upstream treatment, pressure, chamber configuration, power, monitoring and installation position.
What maintenance does UV need?
Check lamp status, keep the quartz sleeve in suitable condition, respect flow conditions and follow the manufacturer or service schedule.
Does UV protect water after the chamber?
UV is one barrier; storage, pipework and outlets still need appropriate hygiene.
When is RO or softening also needed?
RO may be considered for high TDS or dissolved contaminants, while softening addresses hardness and scale. UV solves a different part of the brief.
Need a commercial UV system?
Tell us where UV is needed and what water it will treat. We can also assess the filtration or RO stages around it.
