MBBR SUBSTRATE

Description

MBBR microbiological buffer – what is MBBR microbiological substrate?

1. MBBR microbiological buffer or MBBR microbiological substrate (or vehicle pellet microbiological substrate) is a plastic material used for microorganisms to adhere to and be added in the wastewater treatment system, specifically biological tanks to improve the treatment efficiency of this tank in particular and the whole system in general. Simply understood as a habitat, a habitat of microorganisms, it can be made from relatively durable plastic in the wastewater environment.

2. Properties

• Good biofilm quality and difficult to fall off the material
• Highly hydrophobic, has good adhesion
• Good wastewater treatment especially nitrogen, phosphorus, BOD, COD,..
• Takes up little tank space
• Can be dropped directly into the tank without worrying about clogging problems
• Low maintenance cost
• Low amount of sludge generated
• Compared to other technologies, there is less odor
• Can be used for all types of tanks of various shapes.

What is MBBR technology?

MBBR is an acronym for the phrase Moving Bed Biofilm Reactor. This is an artificial treatment process through the application of internal materials as a substrate for microorganisms to adhere to grow and develop. The substrate material here must have a lighter density than water to ensure suspended conditions. Thanks to the blowers and paddles, these substrates will work non-stop throughout the tank.

It is an effective biological treatment process thanks to the combination of activated carbon sludge and biofilm. The technology also uses the high-powered BioChips MicroOrganism device in aeration and anoxic tanks.

How does the MBBR tank work?

Wastewater will enter the tank after going through anaerobic and chemical biological treatment. Air blowing system with the purpose of making the substrates able to move continuously. These microorganisms, after adhering to the substrates, will support the decomposition of organic matter in wastewater. As a result, the wastewater treatment system operates in accordance with the set standards. Concrete:

• The MBBR tank uses MBBR mobile microorganisms in the aeration tank to increase the amount of microorganisms available for wastewater treatment. Microorganisms will decompose all organic matter in wastewater. Next, the air blowing system will help stir the substrates in the tank to ensure that the microbiological substrates are continuously disturbed during the wastewater treatment process.
• Growing microorganisms will adhere to the side of the substrate to support the degradation of organic matter in wastewater and help the wastewater meet standards. Microorganisms here can be aerobic microorganisms, anaerobic microorganisms.

Features of MBBR wastewater treatment technology

1. What are the advantages of MBBR wastewater treatment technology?

• Durable microflora: The processing microflora is easy to recover thanks to the application of microbial substrates, helping to create a protective biofilm.
• High microbiological density: compared to conventional air blowing tanks, the microbiology treated in each unit volume has a higher density, so the volume of the tank to be treated is smaller, providing higher efficiency of organic matter treatment.
• Specific microbial strains: there are different groups of microorganisms developing between the microbial films, which helps the biofilms to be developed in a tendency to focus on specific organic matter.
• The ability to save energy.
• Small size, convenient in operation and easy upgrade.
• High load capacity and large pollution fluctuations: biofilms have the ability to grow according to the increasing load of organic matter, making MBBR tanks able to operate with high loads, large fluctuations. BOD treatment efficiency is up to 90%, removing nitrogen in wastewater.
• Easy-to-control system: additional Biofilm substrates can be added in proportion to the pollution load and wastewater flow.
• Saving space: reducing tank volume by 30-40% compared to suspended activated sludge technology. Can be combined with many other processing technologies for optimal efficiency.

2. Does MBBR domestic wastewater treatment technology have disadvantages?

• There should be sedimentation and filtration works behind MBBR
• The quality of the MBBR substrate affects the adhesion quality of microorganisms.
• After a period of use, the MBBR microbiological substrate is very fragile.

3. Scope of technology application

– MBBR technology is applied to the wastewater treatment industry, especially wastewater with separate or simultaneous biological pollution of basic compounds (BOD, P, N) such as:

• Domestic wastewater: from schools, hotels, restaurants, residential areas,…
• Wastewater from hospitals, clinics, clinics,…
• Wastewater generated through the production process: seafood processing, food, beverages, industrial wastewater,…

– MBBR tanks have 2 types: aerobic MBBR and lack of air, helping to ensure the treatment of nitrogen in stocked wateri.
