Application of MBBR technology in wastewater treatment

What is MBBR technology? How does it work?

Moving Bed Biofilm Reactor (MBBR) is a biotechnology used in wastewater treatment processes and suitable for municipal and industrial applications. Another common name is the moving bed membrane reactor. MBBR was invented in the 1980s and provides an economical solution for wastewater treatment. STP MBBR technology uses moving bed biofilm reactors in wastewater treatment plants.

The MBBR wastewater treatment system can achieve efficient treatment results with low energy consumption. This technology is used to separate organic matter, nitrification, and denitrification. The MBBR design consists of an activated sludge aeration system. The sludge is collected on plastic carriers with a large internal surface area. The carrier's surface area optimizes contact with water, air, and bacteria.

MBBR-activated sludge is the application of MBBR media in upgrading and transforming overload treatment plants.

MBBR is suitable for wastewater treatment of different water qualities. The application depends on the desired results and regulations controlling emissions. Depending on specific needs, the system can be divided into multiple stages. Individual screens separate these stages to ensure that bacteria remain in their specific areas.

Application of MBBR filler in wastewater treatment

Aeration tank: This tank is similar to an activated sludge tank. Aeration is used to maintain activated sludge and re-lift movement. The MBBR system separates excess bacteria and sludge and sends it to the final separator.

Special plastic carriers: They provide a surface for biofilm growth. The carrier material is made of a material with a density close to water (1g/cm3), such as high-density polyethylene (HDPE) with a density of 0.9g/cm3. These carriers are moved through the tank through an aeration system. This ensures good contact between the wastewater and the biomass on the carrier.

Advantages of MBBR technology

• Compact and space-saving

• Easy to maintain

• Suitable for large capacity loads

• Easy to expand, achieved by increasing the filling degree of the carrier

• Reduce emission costs

• MBBR is not affected by the pool body

• Independent process performance because there is no sludge return pipe; MBBR eliminates return-activated sludge (RAS)

• Efficient sludge retention time (SRT) improves the efficiency of the nitrification process

• Lower sludge production

• No need to recycle activated sludge system

• Introduce abbr filler to transform the existing pool body and increase the capacity

Small Boss MBBR biological filler can be used in any type of pool without a particular pool. If the system is changed to an MBBR treatment system, the most important thing is that MBBR can make full use of the pool capacity; compared with the activated sludge method, the reaction efficiency is increased by 5 to 10 times; nitrification and denitrification are carried out at the same time, which can achieve better nitrogen and phosphorus removal; low loss, not easy to block, no need for backwashing; no bracket is needed, just put Small Boss MBBR biological filler directly; Small Boss MBBR biological filler flows freely and can be cut Bubbles in the water increase dissolved oxygen in the water and save energy consumption.

• Simple and easy to upgrade, small footprint

• Save carbon sources, short water retention time, and high reaction efficiency;

• The effluent water quality has been significantly improved, and COD, BOD, and ammonia nitrogen have been significantly reduced;

• Can resist the significant impact of water and maintain stable treatment effect;

• Even in low-temperature environments, Small Boss MBBR biological filler can operate normally;

MBBR technology is suitable for industrial, municipal, aquaculture, rural, urban, and other sewage treatment.

Operation and maintenance of MBBR bio filter

The continuous use of MBBR biofilm does not require backwashing or sludge return. Sewage treatment tanks have lower operating costs because of the coarse bubble aeration in the aeration zone. Stir constantly to move the carrier above the pool to eliminate clogging.

The maintenance of the MBBR biological filler system is mainly carried out through screening, sludge treatment, water inlet balancing, etc. It also involves the maintenance of the integrated control system and clarification system. MBBR requires skilled personnel to perform routine monitoring. MBBR biofilter technology has a self-maintenance mechanism for the level of biofilm.
