It all began in 1996 when Skjølstrup & Gronborg A/S was founded by company owners Ole Gronborg and Jens Skjolstrup. The first innovative UV systems were based on knowledge gained from various research activities within water treatment conducted at Aalborg University, Denmark.

In addition to ultraviolet sterilization, research work focused on technologies such as ozonation, biofiltration and filtration of particles (particle analysis). Due to increasing commercial activities, research professorships were gradually reduced over time. UV systems were marketed under the ULTRAAQUA brand name.
