Abstract
A photobioreactor system including a light source, a plurality of interconnected pipes, and a liquid slurry containing an algae disposed within the pipes. The pipes are formed from a translucent polyvinyl chloride material that allows light having a plurality of wavelengths emitted from the light source that stimulate growth of the algae to pass through the material and is resistant to light having a wavelengths emitted from the light source that degrade the material.
Claims20
A photobioreactor, comprising:
- a pipe having a wall configured to allow light to pass therethrough;
- and
- a slurry containing an algae, wherein said pipe is formed from a polyvinyl chloride material that resists degradation from predetermined wavelengths of light.
A photobioreactor system, comprising:
- a plurality of interconnected pipes;
- and
- a liquid slurry containing an algae disposed within said pipes,
- said pipes being formed from a translucent polyvinyl chloride material that allows light having a plurality of first wavelengths that stimulate growth of said algae to pass through said material and is resistant to light having a plurality of second wavelengths emitted that degrades said material.

A photobioreactor system, comprising:
- a plurality of interconnected pipes supported by a frame;
- a liquid slurry containing an oil-producing algae disposed within said pipes;
- and
- at least one pump for circulating said slurry through said interconnected pipes,
- said pipes being formed from a translucent polyvinyl chloride (PVC) material that absorbs ultraviolet wavelengths of light to prevent said PVC material from degrading, said PVC material allowing wavelengths of light greater than UV to pass through said material to cultivate growth of said algae during circulation of said slurry in said pipes.
