System and method for culturing algae
First Claim
1. A system for culturing algae comprising:
- a culture pool for exposing a culture fluid containing said algae to sunlight;
a culture tank having a larger depth than said pool, which is disposed adjacent to said pool;
a supply means for supplying said culture fluid from said pool to said tank; and
at least one filter means disposed outside of said culture tank and above said culture pool such that said at least one filter means receives said culture fluid overflowed from said culture tank for removing grown algae from said culture fluid and a filtrate containing immature algae passing through said at least one filter means is returned to said pool.

Abstract
A system and method for its use for efficiently culturing algae such as Spirulina are provided. The system comprises a culture pool for exposing a culture fluid containing the algae to sunlight, a culture tank having a larger depth than the culture pool, which is disposed adjacent to the culture pool, a supply unit for supplying the culture fluid from the culture pool to the culture tank, and at least one filter for removing grown algae from the culture fluid overflowing from the culture tank to the culture pool, while allowing to return a filtrate containing immature algae to the culture pool. It is preferred that this system further comprises a unit for mixing a gas containing carbon dioxide in the culture fluid to be supplied in the culture tank, and a lighting unit disposed in the culture tank to provide an artificial light to the culture fluid. In this case, it is possible to carry out the photosynthesis of the algae night and day.

14. A system for culturing algae comprising:
-
a culture pool for exposing a culture fluid containing said algae to sunlight; a culture tank having a larger depth than said pool, which is disposed adjacent to said pool; a supply means for supplying said culture fluid from said pool to said tank; at least one filter means disposed at the outside of said culture tank and above said culture pool such that said at least one filter means receives said culture fluid overflowed from said culture tank to remove grown algae from said culture fluid and the filtrate containing immature algae passing through said at least one filter means is returned to said culture pool; and an optical fiber bundle disposed in said culture tank to radiate a light to said culture fluid in said culture tank, said bundle comprising optical fibers having different lengths such that light-radiation ends of said optical fibers are uniformly distributed with respect to a depth direction of said culture tank. - View Dependent Claims (15)
