• A Moving Bed Biofilm Reactor (MBBR) also known as MBBR media 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
  • Arvind Envisol is a MBBR provider with a higher surface are compared to other providers in India

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
