Companies that must generate and treat wastewater can benefit from the Moving bed Biofilm Reactor (MBBR).
MBBR is a biological wastewater treatment process with beneficial properties that replace traditional processes such as activated sludge and trickle filters.
The MBBR is exceptional when it comes to elements such as ease, efficiency, and flexibility.
What is biological sewage treatment?
Before discussing the details of MBBR, it is helpful to understand the general categories in which this type of wastewater treatment is categorized. MBBR is a biological process as opposed to a chemical or mechanical process.
The technical breakdown of what makes the biological process stand out is as follows:
The biological water treatment process uses small organisms such as bacteria and nematodes to break down waste. Look at all the organic matter present in the wastewater. Biological processes uses natural cellular processes to break down this waste.
When certain microorganisms are introduced into the sewage, these microorganisms decompose and consume the waste they meet, allowing nature to follow its path. For complex wastes in water, microorganisms can convert them into simpler substances and further treat them for filtration. Biological wastewater treatment is often the next step after pre-treatment to remove certain substances. Other processes may be involved even after a biological process. Biological wastewater treatment processes are effective, environmentally friendly, and economical, either alone or as part of a more comprehensive water treatment process.
Now that the basics of biological wastewater treatment have been covered, it is time to focus on specific biological treatment methods, mobile bed biofilm reactors.
Norwegian researchers developed MBBR technology in the late 1980s and early 1990s. The purpose of MBBR was to effectively compensate for some of the problems that characterize other biological wastewater treatment processes. MBBR combines the many strengths of biological processes, especially activated sludge processes and biofilm media, to eliminate or minimize the defects commonly found in biological wastewater treatment processes.
MBBR has become a popular method of biological wastewater treatment because of the many benefits it offers. MBBR uses a biofilm-covered plastic carrier to break down waste. In addition to being an effective means of removing organic matter, MBBR is also an innovative process for nitrification and denitrification.
How does MBBR wastewater treatment work?
Here's a more detailed breakdown of how the MBBR process works:
A useful way to understand this process is to explore the various MBBR design components that work together to enable this technique.
Basin: The MBBR process takes place in a basin, also known as a reactor or aeration tank. The size of this container depends on the filtration requirements of your facility. Inflows may enter this basin for treatment and a second basin for further MBBR treatment or other types of water treatment processes. The MBBR aeration tank has an open top that exposes water to the open air for an aerobic filtration process.
Media: The pool is full of thousands of small plastic chips called media or carriers. These media can occupy up to 50-70% of the tank. Their design maximizes the surface area provided for the growth of biofilms. They mimic the density of water and allow it to be mixed with liquids instead of floating or sinking.
Ventilation Grill: Another thing that helps the media move effectively through the tank is the Ventilation Grill. This device is essentially a fan at the bottom of the reactor tank. Ventilation grills help keep the wearer moving, contacting all existing waste and efficiently decomposing it, introducing more oxygen into the tank.
Sieve: The mesh material allows water to pass through but keeps the plastic straps in the pool. Microorganisms attached to the medium in the tank consume waste in the water, making it cleaner and safer for reuse and disposal. The type of microorganisms introduced into the tank depends on the type of waste that needs to be disposed of.
As mentioned earlier, MBBR is not just used to consume general waste, it also plays a role in nitrification and denitrification.
Nitrification is the process of converting ammonium to nitrate, and denitrification occurs when oxygen is metabolized, and nitrate is converted to nitrogen gas. Both are biological processes, so MBBR is a great way to make them possible.
Again, the purpose of the MBBR process is to determine the type of microorganism introduced. For example, for denitrification, it is best to use denitrifying bacteria such as Pseudomonas, Para coccus, and Alcaligenes. MBBR is a valuable tool whenever biological processes are needed to improve the quality of wastewater.
