APPARATUS FOR PROVIDING CULTURE MEDIUM FOR MARINE PLANTS

PURPOSE: A marine algae culture fluid feeder capable of promoting the growth and the photosynthesis of marine algae is provided to supply nutritive salts in culture fluid in the proper pressure and concentration. CONSTITUTION: A marine algae culture fluid feeder comprises the following: a pipeline(110) installed in between nutricline formed with nutricline water(W1) containing nutritive salts and a culture field for growing marine algae; a first pump(120) installed on the pipeline, collecting the nutricline water; a dissolving unit(140) connected to the pipeline to receive the nutricline water, and dissolving carbon dioxide in the nutricline water to obtain a solution(W2); a second pump(160) supplying the solution to the culture field; a nutritive salt concentration controller(130) controlling the concentration of the nutritive salts to the requested value from the culture field; a pressure controller(150) connected to the dissolving unit for minimizing the emission amount of carbon dioxide from the solution to the atmosphere; a distribution pipe(170) uniformly supplying the solution to the culture field; and a solution spraying unit(180) upward-spraying the solution inside the culture field.
