(MBBR) MOVING BED BIOFILM REACTOR

• 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

• 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

• 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.
