Disinfection of Tanks

Microfloat® - UV-Disinfection of Closed Tanks

Microfloat® and Microspear® were developed as a chemical-free method to disinfect water in storage tanks by UV irradiation. Microfloat® (floating UV lamp) is applied in closed tanks of static and strongly varying fill levels. Microspear® (immersed UV lamp) is used in tanks and rinses of static fill levels and also for machinery.

Microfloat® irradiates the water, the walls of the tank above and below water level as well as the air above the surface with UV-C light, to sterilize the water and avoid the developing of a bio-film.

In doing so, we ensure that the water is disinfected and avoid its reinfection.

Microfloat® disinfects the whole tank (liquid, atmosphere and tank surface) by building up a germ barrier.

This chemical free solution offers a higher efficiency compared to chemicals, because germs cannot develop resistances against UV irradiation.

Furthermore, this process works without the negative side effects of biocides (i.e. corrosion, usage of toxic chemicals).

The data below are based on our standard products, tap water quality and fixed tank-size / flow-rate ratio.

Please contact us for additional sizes and system requirements!

All Microfloat® - UV-units are supplied together with an electrical cabinet and, where appropriate, for several floaters.

UV-Disinfection with a flexible design

The UV-units Microfloat® and Microspear® can be assembled to complete UV-systems adapted to:

- the shape of the tank

- the flow rate

- the water quality.

In doing so, we can supply optimal customer-fit UV-disinfection, without chemical side effects.


Which data do we need to provide a quote for a well-designed system?

1. Tank dimensions: LxWxH or DxH in m

2. Filling volume in m³

3. Flow in m³/h

4. Water sample (50mL) or description of the water (e.g.: DI-Water, recycled water, rain water, ...)

5. Construction material (tank)

6. Temperature of the medium

Please send this data to your contact person or to: info(at)enviolet(dot)com .

We will then get in touch to give you a quote of a well-designed system.
