FBBR or MBBR, the right solution for each project

Both technologies deliver effective biological filtration. The best choice depends on production goals, water quality, solids management and how the facility will be operated.

Biofilter TECHNOLOGIES

Different strengths, same goal

Fixed Bed Biofilm Reactor (FBBR) and Moving Bed Biofilm Reactor (MBBR) solve the same task in different ways. At Pure Salmon Technology, we evaluate every project before selecting the most suitable solution.
