Moving Bed Biofilm Reactor(MBBR) Biological Filler Bio Carrier For
Domestic And Industrial Sewage Treatment-MH-Series
ARTICLE
Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at the Norwegian University of Science and Technology in the late 1980s.[1] The process takes place in an aeration tank with activated sludge
and uses floating, recycled plastic carriers that a biofilm can
grow on. The compact size and cheap wastewater treatment costs
offer many advantages for the system. The main objective of using
MBBR is water reuse and nutrient removal or recovery. In theory,
wastewater will be no longer considered waste, it can be considered
a resource.
OVERVIEW
Due to early issues with biofilm reactors, like hydraulic
instability and uneven biofilm distribution, moving bed biofilm
technology was developed.
The MBBR system consists of an aeration tank (similar to an activated sludge tank) with special plastic carriers that provide a surface where a
biofilm can grow. There is a wide variety of plastic carriers used in
these systems. These carriers vary in surface area and in shape, each offering
different advantages and disadvantages.
The surface area plays a very important role in biofilm formation.
Free-floating carriers allow biofilms to form on the surface,
therefore a large internal surface area is crucial for contact with
water, air, bacteria, and nutrients. The carriers will be mixed in the tank by the aeration system and
thus will have good contact between the substrate in the influent
wastewater and the biomass on the carriers
The most preferable material is currently high-density polyethylene
(HDPE) due to its plasticity, density, and durability.
To achieve a higher concentration of biomass in the bioreactors,
hybrid MBBR systems have been used where suspended and attached
biomass co-exist contributing both to biological processes.
FEATURES
Large specific surface area, more attached microorganisms
No need bracket, easy to fluidize, save energy
Fast and easily to hang membrane, high biological activity
Strong impact resistance, long lifetime
Excellent nitrogen and phosphorus removal effect
Small footprint, simple and flexible operation management
Good hydrophilicity, good treatment effect
Relying on biofilm treatment, reduces the remaining sludge
CURRENT USAGE
Today, MBBR technology is used for municipal sewage treatment,
industrial wastewater treatment, and decentralized wastewater treatment. This technology has been used in many different industries, some
of them being:
- Automotive industry
- Chemical industry
- Food and beverage
- Metal plating and finishing
The MBBR system is considered a biofilm or biological process, not
a chemical or mechanical process. Other conventional biofilm
processes for wastewater treatment are called trickling filters, rotating biological contactors (RBC), and biological aerated filters (BAF).
APPLICATION
ADVANTAGES
Biofilm processes in general require less space than activated sludge systems because the biomass is more concentrated, and the
efficiency of the system is less dependent on the final sludge
separation.MBBR systems do not need recycling of the sludge, which
is the case with activated sludge systems.
The MBBR system is often installed as a retrofit of existing
activated sludge tanks to increase the capacity of the existing
system. The degree of filling of carriers can be adapted to the
specific situation and the desired capacity. Thus an existing treatment plant can increase its capacity without increasing the
footprint by constructing new tanks.
Some other advantages are:
- Increased performance and volumetric treatment capacity
Higher effective sludge retention time (SRT) which is favorable for
nitrification
Responds to load fluctuations without operator intervention
Lower sludge production
Less area required
Resilient to toxic shock
Process performance independent of secondary clarifier (due to the
fact that there is no sludge return line).
