Microfloat® irradiates the water, and the walls of the tank above and below the water level as well as the air above the surface with UV-C-light, so that the water is sterile and no bio-film can grow. This ensures that the water is disinfected and also reinfection of the water is eliminated.

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

This chemical free solution provides a higher efficiency compared to chemicals because bacteria and fungus cannot develop UV-irradiation resistance. The disinfection is continuous and does not require the down time associated with biocide disinfection.

The combined disinfection solution can easily be built into any water vessel, with seamless integration and operation.

The retrofit of existing tanks is easily achieved.

Due to the low energy consumption and high efficiency Microfloat® is the optimum disinfection approach for all tanks with static and varying filling levels.
