How to choose the correct tubing material for photobioreactors?

[Global] Looking for an algae cultivation system with sustainable productivity rates and quantifiable production costs? Searching for a tubular PBR that meets exactly these criteria for your algae cultivation? If you are asking one of these questions, then you should keep on reading.

In order to reach these goals, you should focus on the quality of the tubing that will be used in your PBR design. Why? Because the overall efficiency of the tubular system determines the growth dynamics of the algae within the PBR. The tubes can be produced using various source materials: one being glass and the other being different polymer types such as UV-PVC and PMMA.

On the following, you will find important innovation milestones for glass PBRs in the last five years:

  • Reduced wall thickness of the glass tubing
  • Production of longer length tubing segments
  • Introduction of industry grade couplings
  • High precision glass u-bends and manifolds
  • Vertical system design of PBRs
Schott photobioreactor couplings on the U-bends.

Schott AG, the world’s largest industrial glass tube manufacturer,  is now providing a guideline where glass and polymer tubing are systematically compared for use in a PBR. After reading this, you will understand which material is suitable for certain applications. Then you can make an informed decision based on your own requirements.

In the last five years, photobioreactors (PBRs) made of glass have seen significant improvements through a variety of innovations. On the one hand, improved production processes are combined with lower costs. On the other hand, standardized PBR components lead to increased productivity. Moreover, improved system design of the reactor leads to new heights in productivity rates

If you want to build a highly productive PBR with an excellent price performance ratio, you should know what the most important technical innovations of the past few years are. You will find out what these are in this guide.
