  • Polishing effluent from municipal waste water treatment works. The drumfilter can also replace primary or secondary clarifiers.
  • The Hydrotech Drumfilter is specially suitable in fish farming systems where it is essential to prevent the particles from fragmentation. Both in recirculated systems and in open systems for intake and outlet water.
  • Food processing industries are using the Hydrotech Drumfilter for treatment of waste water and for filtering CIP rinse water.
    Other examples are filtering transport water in plastic industries and purification of scrubber water in power plants
