What is ultraviolet light, and what is the connection between wavelength and the effectiveness of the bactericidal action?

The UV lamp helps reduce the bacterial load in the water. The UV lamp in Strauss
Water appliances emits a specific wavelength. The wavelength affects living
organisms, and the shorter the length, the deadlier the effect. The strength of the UVbeam in our water bars prevents bacteria from multiplying. The great advantage of
the system is the efficiency and speed with which it eliminates bacteria.
