Professor Hallvard Ødegaard of the Norwegian University of Science and Technology invented the moving bed biofilm reactor (MBBR), a type of wastewater treatment process, in the late 1980s.(Source: ) The procedure uses floating, recycled plastic carriers that a biofilm can grow on in an aeration tank with activated sludge. The system has several benefits, including its small size and inexpensive wastewater treatment. Reusing water and recovering or removing nutrients are the two main goals of MBBR. Theoretically, wastewater is now a resource rather than a waste.
Moving bed biofilm technology was created in response to early problems with biofilm reactors, such as hydraulic instability and uneven biofilm distribution. The MBBR system consists of an aeration tank with unique plastic carriers that offer a surface for the growth of a biofilm, resembling an activated sludge tank. These systems make use of a large range of plastic carriers. Each of these carriers has a different shape and surface area, as well as unique benefits and drawbacks.
For contact with water, air, bacteria, and nutrients to occur during biofilm formation, a large internal surface area is essential. As a result, free-floating carriers play a crucial role in the formation of biofilms on surfaces. When combined in the tank by an aeration system, carriers guarantee that the biomass on them and the substrate in the influent wastewater make good contact.
This mixing facilitates the breakdown of organic compounds in the wastewater and effective removal of pollutants.
Hybrid MBBR systems, in which suspended and attached biomass coexist and contribute to biological processes, have been used to increase the concentration of biomass in the bioreactors. High-density polyethylene (HDPE) is currently the material of choice because of its durability, density, and plasticity.

Present Applications of Reactor Mbbr Filter Sludge Biological Filler

MBBR technology is currently utilized for wastewater treatment in a number of industries, including decentralized, industrial, and municipal wastewater treatment. It has been used in many different industries, such as:
Automobile sector
chemical sector
Food and drink
The Petrochemical Sector
The MBBR system is considered a biological or biofilm-based process, as are other traditional biofilm methods for treating wastewater, such as trickling filters, revolving biological contactors (RBC), and biological aerated filters (BAF). For these processes to break down organic matter and extract pollutants from wastewater, microorganisms in biofilms must grow.

The characteristics of Reactor Mbbr Filter Sludge Biological Filler

Greater number of attached microorganisms, larger specific surface area.
Bracket not needed; fluidizes easily; saves energy.
membrane that hangs quickly and readily, with high biological activity.
Long lifespan, strong resistance to impact.
Excellent removal of nitrogen and phosphorus.
Compact size, straightforward and adaptable operation management.
Excellent hydrophilicity and efficacious treatment.
By using biofilm treatment, the amount of leftover sludge is decreased.

The benefits of Reactor Mbbr Filter Sludge Biological Filler
Because biofilm processes have a higher biomass concentration and less reliance on final sludge separation, they typically take up less space than activated sludge systems. Sludge recycling is not necessary for MBBR systems, in contrast to activated sludge systems.
The MBBR system is frequently installed as a retrofit to increase the capacity of already-existing activated sludge tanks. The carriers' filling level can be changed based on the particular circumstance and required capacity. Because of this, treatment plants can add more tanks to their capacity without increasing their physical footprint.

Improved effectiveness and capacity for volumetric treatment
Extended periods of effective sludge retention time (SRT) are advantageous for nitrification
The load fluctuations are handled by the MBBR system without the need for operator intervention.
Reduced production of sludge.
Less space needed
Able to withstand toxic shock
Process performance is independent of the secondary clarifier (because there isn't a return line for sludge).
