Biography
Idar Schei is holding a MSc in sanitary engineering from NTNU, Norway, of 1973. He has been in
SINTEF (an independent research institute in Norway with >2000 employees) as a researcher within
water flow in pipes and tanks and reservoirs for 3 years, then 8 years as professional engineer in a private
consultancy company, working with design, engineering and supervising of constructions of water
treatment plant for municipalities. From 1982 also design of Salmon farming facilities. From ’85-’93 he
was Head of the aquaculture research program at SINTEF, and also involved in R&D projects within
water hydraulics in fish tanks and RAS. In 1993 he founded AquaOptima AS with some colleagues from
SINTEF, to industrialize patented technology and know-how from the R&D activity, and has since then
been the CEO of AquaOptima AS. Idar Schei has written publications regarding water hydraulics in tanks
and its impact of water quality and fish welfare, and within the importance of solids removal from tanks
in RAS, and given presentations at several international conferences.
