UV sterilizer
Ultraviolet water treatment to reduce bacterial, viral and fungal load in RAS - without reagents or chemical changes.
- Dose
- up to 60 mJ/cm²*
- Productivity
- 10–300 m³/h
- Control
- online UV sensor
*For viral load and spores, focus on 80–120 mJ/cm² - we check according to the specifications and UVT of the water.

Biosafety without reagents
What does the equipment solve?
- Stable dose of UV-C to inactivate bacteria, viruses and spores without by-products.
- Online intensity control and lamp aging compensation.
- Accounting UVT (water transparency at 254 nm) - maintaining a given dose during quality fluctuations.
- Works in pressure and non-pressure lines, low pressure losses.
Equipment
- Stainless steel chamber AISI 316L / PVC-U steel with polished internal surface.
- Quartz sleeves with manual or automatic cleaning (scraper/hydro).
- LPHO (long life, low temperature) or MP (high power, compact) lamps are up to the task.
- UV intensity, flow, temperature sensors; differential sensor for contamination signaling.
- Control panel: hour meter, lamp dimming, alarms, SCADA interfaces.
How does it work and what doses are needed
Water passes through a chamber with 254 nm UV lamps. The actual dose depends on the lamp power, residence time and UVT. The system maintains the target dose by adjusting the power and warns of a drop in transparency or contamination of the cartridges.
- Head loss: typically 0.05–0.25 bar (depending on flow rate and layout).
- Temperature: lamp overheating control and automatic power reduction.
- Pre-filtration: microfilter/drum 50–100 µm for stable UVT.
- Total bacterial load: 30–40 mJ/cm².
- Viruses/spores/mold: 60–120 mJ/cm² (depending on UVT and type).
- Work on RAS return: 40–80 mJ/cm² at UVT ≥ 90%.
- Source water intake: we specify the dose based on turbidity, color and UVT.
We set the exact values after measuring the UVT (254 nm) and the flow rate along the circuit.
Options and integration
- LPHO — long service life (8–12 thousand hours), high dose stability; MP - compact at high costs.
- Horizontal/vertical housing, flange connections, drain and air vent for service.
- Duplicate sections for critical lines with automatic bypass.
- Integration with SCADA: UV intensity trends, lamp life, differential pressure signals.
Options and Security
- Automatic cleaning of sleeves, position sensor of the cleaning mechanism.
- Interlocking: no flow → stop lamps; overheating - reduction in power/stop.
- Antibacterial coating of gaskets, materials - drinking grade.
- Spare set of lamps and sleeves, set of seals, assembly paste.
Frequently asked questions
How critical is UVT?
UVT directly affects the dose: when transparency decreases, the same lamp power produces less J/cm². The system measures UV intensity and compensates by dimming, but it is better to stabilize the original UVT by filtration.
LPHO or MP lamps?
LPHO - maximum dose stability and resource. MP - compact power for high flow rates, but higher thermal load. We will select according to flow rate, UVT and required dose.
