Method of facilitating growth of specific microorganisms
A method of using algae to remove a contaminant or pollutant from a first fluid is provided. The method can include providing a growing apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid, and growing the algae using the growing apparatus. The method can further include exposing the algae to the first fluid within the first reservoir where the algae uptakes the contaminant or pollutant from the first fluid, and exposing the algae via a belt to the second fluid in the second reservoir where the algae is stimulated to release the contaminant or pollutant. Exposing the algae to the first fluid within the first reservoir or the second fluid may change a growth rate of the algae.
1. A method of using algae to remove a pollutant from a first fluid, the method comprising:
providing an apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid;
associating the apparatus with algae;
exposing the algae to the first fluid within the first reservoir wherein the algae uptakes the pollutant from the first fluid; and
exposing the algae to the second fluid in the second reservoir wherein the algae is stimulated to release the pollutant,
wherein exposing the algae to the first fluid or to the second fluid changes a growth rate of the algae, and
wherein following release of the pollutant, the algae is then brought back to the first reservoir to uptake additional pollutants.
2. The method of claim 1 , wherein exposing the algae to the first fluid or exposing the algae to the second fluid facilitates the growth rate of the algae.
3. The method of claim 2 , wherein exposing the algae to the first fluid or exposing the algae to the second fluid facilitates the growth rate of a predetermined species of the algae.
4. The method of claim 1 , wherein the algae is exposed to the second fluid via a belt, wherein the belt moves in a continuous manner.
5. The method of claim 4 , wherein the belt comprises a surface and microorganisms growing on the surface.
6. The method of claim 5 , wherein the belt comprises bacteria, fungi, the algae, or a combination thereof.
7. The method of claim 6 , wherein exposing the algae to the first fluid or exposing the algae via the belt to the second fluid facilitates a growth rate of the bacteria, the fungi, the algae, or the combination thereof.
8. The method of claim 1 , wherein the pollutant is nitrogen, phosphorous, potassium, carbon, a toxic metal, a salt, a pharmaceutical, a pharmaceutical and personal care product, or a hormone.
9. The method of claim 1 , further comprising starving the algae of the pollutant by exposing the algae to the second fluid thereby causing the algae to consume increased amounts of the pollutant from the first fluid in the first reservoir.
10. The method of claim 1 , further comprising concentrating the pollutant within the second fluid in the second reservoir.
11. The method of claim 1 , wherein a first temperature of the first fluid is lower than a second temperature of the second fluid.
12. The method of claim 11 , further comprising controlling the second temperature of the second fluid.
13. The method of claim 1 , wherein the second fluid is illuminated using increased light intensity.
14. The method of claim 1 , wherein the algae is exposed to a sorbent material.
15. The method of claim 1 , further comprising controlling a temperature of air or light within the apparatus.
16. The method of claim 1 , further comprising harvesting the algae.
17. A method of using microorganisms to remove a pollutant from a first fluid, the method comprising:
providing an apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid;
associating the apparatus with microorganisms;
exposing the microorganisms to the first fluid within the first reservoir wherein the microorganisms uptake the pollutant from the first fluid; and
exposing the microorganisms to the second fluid in the second reservoir wherein the microorganisms release the pollutant,
wherein exposing the microorganisms to the first fluid or to the second fluid changes a growth rate of the microorganisms, and
wherein the microorganisms are starved of the pollutant by exposing the microorganisms to the second fluid thereby causing the microorganisms to consume increased amounts of the pollutant from the first fluid in the first reservoir.
18. A method of using microorganisms to remove a contaminant from a first fluid, the method comprising:
providing an apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid;
associating the apparatus with microorganisms;
exposing the microorganisms to the first fluid within the first reservoir wherein the microorganisms uptake the contaminant from the first fluid; and
exposing the microorganisms to the second fluid in the second reservoir wherein the microorganisms release the contaminant,
wherein exposing the microorganisms to the first fluid or to the second fluid changes a growth rate of the microorganisms, and
wherein the microorganisms are starved of the pollutant by exposing the microorganisms to the second fluid thereby causing the microorganisms to consume increased amounts of the pollutant from the first fluid in the first reservoir.
