Voigtlaender´s business purpose is the development, construction, trade and operation of highly efficient water treatment technology along the entire value chain. It is Voigtlaender´s credo to clean every kind and quality of water: Sea-, surface-, ground-, river-, lake-,  waste-, production-, process-water etc. including elimination of hazardous heavy metals as cadmium, mercury etc.
 
The central product of all Voigtlaender services is a generator with an cell inside, which is disinfecting water by electric impulses – the so called cell membrane electrolysis. With other words a cell is the key of Voigtlaenders operational actions and to efficient clean waters.

Combining the words cell and key sounds like “selkie”. Selkies are mythological creatures only found in very clean, fresh sea waters. Selkies are said to live as seals in the sea, but able to undergo a metamorphosis into a human.
 
So the idea was, to develop a symbol as well as a logo for water treatment etc. by combining the name “Voigtlaender” (as the eponym of the invention) with a sign for clean water: The fin of a seal, a whale or even a mermaid.
