If your pilot plant rougher flotation stage time is at around 20- 30 minutes and you are getting the recoveriesand concentrate grades that you are looking for then you should be safe to use a scale up factor of 1 or 1.1. If you are around 15-20 minutes of flotation time on cleaner stages and you are getting the recoveries and concentrate grades ...

It is clear that the full-scale plant performance is not as good as that of the pilot plant in flotation. After flotation, the average chlorophyll-a reduction is approximately 80% (compared with the average value of 91% for the pilot plant); interestingly, full-scale plant showed a better performance for filtered water in chlorophyll-a reduction.
