ACMBRHyDAF

Characteristic

  • Unlike the existing MBR method, cleaning is possible without a separate lifting device and the cleaning time is short.
         (Installation cost is cheaper than the existing MBR method, construction time is shortened and maintenance is easy.)
  • It can be installed in the old biological treatment system without additional civil engineering work.
  • Since the washing water is circulated and cleaned automatically, the washing efficiency is improved and the life of the membrane is long.
  • As it is installed separately, rather than installed in an aeration tank, like the MBR method, it is possible to prevent sludge bulking and loss of sludge caused by PIN-FLOC and to ensure stable water quality.
  • Independent nutrients such as nitric acid bacteria can be maintained at high concentrations, so it is efficient for nitrification process and can operate at low FM ratio.

  • Very little sludge
  • Excellent response to load fluctuations
  • Low maintenance cost
  • No sludge bulking concept
  • Excellent treatment water quality
  • Expect high processing efficiency with easy operation
  • Long-term aeration causes little excess sludge.
  • Stabilized treated water
  • Suitable for small and small treatment plants
  • Long time to trap sludge

Disadvantages

  • Regular cleaning required

  • Long term aeration to increase scale
  • Sludge return require
  • Maintenance cost is high
  • Difficulty controlling attached organisms
  • Requires contact material
  • High dependence on universal structure
  • Settling tank required for actual operation
  • Rapid deterioration of water quality if anaerobic occurs and detached during long-term operation inside attached microorganisms
