Reduced biofouling due to longer tubing sections
By using high-end glass tubes in your tubular PBR, you can significantly reduce the risk of interrupting your production due to biofouling. The main reason for this is that tubes made of high-end glass can be manufactured significantly longer.
The more tube segments that are required and interconnected within a PBR system, the higher the chance for the formation of biofilm. Why is that?
In the areas where the tubes are connected with couplings, it is unavoidable that small crevices occur, which form a breeding ground for bacteria. Over time, this eventually leads to biofouling.
In general, it can be said that the less connectors or couplings that you use within a PBR, the less biofilm will form over time. It is therefore desirable to reduce the amount of connections for the tubes while still reaching the desired length or volume specification of the overall PBR. As an additional benefit, the intervals between cleaning become longer.
When using SCHOTT tubes, you can choose between tube lengths of 1.4, 2.5 and 5.5 meters with a tube diameter of 54 mm or 65 mm.
Regarding transportation, handling and installation it can be said that shorter lengths are easier to handle. So in the end, a compromise must be found between practicability and productivity. While 5.5 meters is the standard for any longer system, you might want to consider shorter tubes for small pilot plants on lab scale PBRs.
