How Do You Grow Chlorella For A Food Supplement?
• Where to grow and how: Chlorella is usually grown in concrete circular ponds up to 45 m in diameter, with agitation by a rotating arm (resembling a clock dial with the second hand running around). or, in horizontal oblong basins (known as “raceway ponds”) in which a 20 – 30 cm thick layer of inorganic nutrient solution with algae, exposed to sunlight and bubbled by carbon dioxide, is continuously moved by means of paddlewheels. • The Tøeboò culture technology: This technology developed and optimized since 1960, is very different. It is based on a system of inclined areas on which the algal suspension continuously flows during the day in a very thin layer at an optimum velocity, being thus intensively mixed. The flow velocity and the roughness of the cultivation surface determine the turbulence. Intensive turbulence optimizes the changes of light and dark periods of individual algal cells, resulting in a high efficiency of light utilization. During the night, the algal suspension is s
