FAQs

What substances do the reactors mineralize (remove)?
They target only organic pollutants. OH radicals break C-C bonds but don’t affect lime or inorganic salts.

Do they alter the water’s conductivity?
No.

Do they modify the water’s pH?
No. OH radicals are not OH ions.

Can they reduce BOD in a single pass?
No. BOD reduction needs water recirculation and varies based on pollutant concentration and type. It’s effective only if pollutants are organic.

Do they risk damaging the infrastructure?
No. However, to prevent galvanic corrosion, insulate hydraulic connections using materials like rubber.

Can a reactor from a defunct installation be reused elsewhere?
Yes, but ensure the reactor model fits the new installation.

Is pre-filtering necessary before using the reactor?
Generally, no, unless there’s particulate matter that might scratch the UV lamp’s protective quartz tubes.

Any specific installation considerations for the reactor?
Ensure at least 1.5 m clearance for hassle-free UV lamp maintenance.

What’s the highest water temperature reactors can handle?
Up to 55ºC. Efficiency might drop after 50ºC, although some reactors operate efficiently even at 62ºC.

What’s the minimum temperature?
1ºC. Avoid water freezing inside reactors.

Can these be set up outdoors?
Some models have IP54 or IP55-rated electrical panels. If exposed to harsh elements, it’s advisable to shield both panels and the reactor.

How far can the control box be from the reactor?
Up to 25 m.

Do reactors replace biocides?
No, although this can vary based on country-specific regulations.

What’s the effect of using reactors with water containing chlorine?
A synergistic effect is observed, amplifying chlorine’s disinfectant action.

How do reactors interact with water containing other biocides?
Typically, a synergistic effect occurs. For instance, using hydrogen peroxide produces even more OH radicals. However, there are exceptions. Introducing a compound with iron, which scavenges OH radicals, can decrease equipment efficiency.

Is there a residual effect from the reactors?
No. OH radicals are produced solely within the reactor and exist for only nanoseconds.

What’s the minimum dose to produce OH radicals?
400 J/m^2.

Can the UV lamp dosage be adjusted?
No. Reactors maintain a constant dosage. They’re unique; while traditional UV systems rely on UV light, these work with OH radicals, which function differently.

What UV wavelength do the reactors operate on?
They operate around a peak of 253.7 nm.

Do you employ various UV lamps?
Yes, we use 80W and 105W UV lamps.

How long do UV lamps last?
Between 14,000 and 16,000 hours.

Can reactors operate only during specific hours?
Yes, but each on/off cycle shortens the lamp’s lifespan by approximately 24 hours.

Is continuous operation of reactors advised?
Absolutely.

What if some UV lamps malfunction?
To ensure effective results, at least 90% of the lamps should remain functional.

Does the control panel require cooling?
In humid or high-temperature settings (above 40ºC), cooling is recommended. We can provide it as an optional addition.

Can reactors be integrated with SCADA systems?
Yes, they’re compatible with RS-485 MOD BUS RTU.

Are there alternative power levels and frequencies for these reactors?
Standard reactors are made for single-phase 230 V | 50 Hz. Custom configurations (in terms of voltage/frequency) are available upon request.

Standard Maintenance Requirements
– Typical duration: Less than 30 minutes monthly and an added 4 hours annually.
– We recommend attending our training programme for a comprehensive understanding.

Reactor Cleaning Frequency
– Based on water quality and indicated by the transmittance sensor.
– At a minimum, clean once a year during the annual maintenance.
– For very hard waters, bi-weekly cleaning may be required.
– Note: Cleaning can be done without shutting down the entire water system.

Cleaning Products and Precautions
– The ideal cleaning agent varies with the type of contamination. Generally, a mild acid like acetic acid is recommended.
– Ensure the pH remains above 4 during cleaning.

Cleaning Procedure
– No need to uninstall the reactor.
– Fill it with diluted weak acid.
– Let it sit for 4 hours.
– Drain and restart the reactor.

Automatic Cleaning
– An automatic cleaning system is available as an optional feature.

Spare Parts
– Reactors within the same series use identical spare parts.
– Some parts are interchangeable between different series.
