Kinds of Closed Systems

Tubes made from glass or polymer are being arranged vertically or horizontally. A pump makes the algae culture pass the tubular system, after which the culture is collected by a tank and recycled again into the tubular system. Closed tubular photobioreactors exist in laboratory and production size as they are the only systems, which are able to produce high-quality biomass for a cost-efficient production of high-end algae products like DHA, Astaxanthin or Spirulina. Algae for dietary supplements are best grown in closed systems as they provide a high degree of purity and productivity, which results in high quality of the end product.
