When CO2 dissolves in water it may appear as H2CO3, HCO3- and CO3
2-, depending on the pH. Dissolution of CO2 in
water can be written as:
CO2 + H2O H2CO3 H+ + HCO3- 2 H+ + CO3
2-
Algae use the CO2 in its HCO3- form and excrete OH- ions that elevate the pH of the pond. Therefore, the pH of the pond
can be used as a monitor to evaluate the state of the pond. If the pH rises (due to OH- ions) then it indicates that optimum
growth is occurring. 8)
Utilization StrategySupply Methods of CO2 in the Seawater 8)
12)Three methods to bubble CO2
into ponds/shallow sea (13~20% CO2 Utilization):
• A is a sintered stone,
• B is a porous pipe with a plastic sheet to trap CO2
bubbles, and
• C utilizes a high speed pressure pump for aeration pressure pump for aeration and mixing.
CO2 supply methods Comments CO2 utilization
Bubbling method Gas is supplied in the form of fine bubbles. Problematic in shallow ponds, residence
time in pond is not sufficient to allow the CO2 to be dissolved. A lot of CO2 is lost
to the atmosphere.
13 - 20%
Floating gas
exchanger
The gas exchanger consists of a plastic frame, which is covered by transparent
sheeting and immersed in the suspension. CO2 is fed into the unit and the exchanger
float on the surface. CO2 needs to be in a concentrated form.
25 - 60%
Diffusion method CO2 is let to diffuse through a porous metal or plastic pipe to form the smallest
bubbles possible (not seen on surface).
