(MBBR) MOVING BED BIOFILM REACTOR


MBBR MEDIA TECHNOLOGY
  • A Moving Bed Biofilm Reactor (MBBR) it consists of an aeration tank which is similar to an activated sludge tank with special plastic carriers that provide a surface where a biofilm can grow.
  • In MBBR technology thousands of polyethylene biofilm carriers are used to operate in mixed motion inside the aeration tank.
  • There is a protected surface on each biofilm carrier which increases the productivity and growth of heterotrophic and autotrophic bacteria within its cells.
  • It is this high-density population of bacteria that achieves high-rate biodegradation within the system while also offering process reliability and ease of operation
Why MBBR?
  • Flexible Design that allows for increased capacity.
  • No operational adjustments, only equipment maintenance.
  • Stable under large load variations.
  • Smaller foot prints.
  • Low investment Cost.
  • Single pass treatment.
  • Multiple applications.
  • Extremely compact and simple biological treatment system
ADVANTAGES of MBBR
  • MBBR system requires a lesser footprint compared to activated sludge system, because the biomass in MBBR is more concentrated and the efficiency of the system is less dependent on the final sludge.
  • MBBR system doesn’t need the recycling of the sludge.
  • An existing plant’s capacity can be increased using MBBR as a retrofit.
  • MBBR has a higher effective sludge retention time (SRT), which is favourable for nitrification.
  • As there is no sludge return time process performance is independent of the secondary clarifier.
