Main working principle

Biofilm technology is based on microorganisms' attachment to a floating plastic medium. This technology utilizes microorganisms' natural degradative capabilities to remove organic matter from wastewater.

An MBBR system consists of a reactor (usually a cylindrical or rectangular tank) and floating plastic media. These plastic media are lightweight, high-surface-area materials floating freely in water.

These plastic media move freely within the reactor, providing a large surface for microorganisms to adhere to. The medium's high specific surface area and unique design enable more microorganisms to adhere to its surface and form biofilms.

Microorganisms grow on the surface of plastic media to form biofilms. This membrane comprises bacteria, fungi, and other microorganisms that effectively degrade organic matter in wastewater. The thickness and activity of biofilm determine the efficiency of wastewater treatment.

Product working process

By optimizing the growth conditions of microorganisms, the efficiency of sewage treatment is improved, which is an essential technical means in modern sewage treatment projects.

·  water ingress stage—

Raw sewage is fed into the reactor.

·  reaction stage —

In the reactor, the sewage is thoroughly mixed with the floating plastic medium, and the microorganisms in the biofilm degrade the organic matter in the sewage.

· Remove sludge —

The treated sewage flows out of the reactor, and at the same time, some microorganisms and sludge are discharged. Part of the biofilm is removed to maintain the system's regular operation.

·  Out of water stage —

The treated sewage undergoes post-treatment processes such as sedimentation or filtration and is discharged into the environment or further processed.

·Efficient processing power —

Since microorganisms can grow on large areas of plastic media, MBBR systems can treat high-concentration organic wastewater. The treated sewage undergoes post-treatment processes such as sedimentation or filtration and is discharged into the environment or further processed.

· Adaptable —

MBBR systems can treat various types of wastewater, including domestic and industrial wastewater.

· Small footprint —

Due to its efficient treatment capacity, the MBBR system requires less floor space than the traditional activated sludge process.

· Easy to operate—

The operation and maintenance of the MBBR system are relatively simple and stable.
