Kangju Machine specializes in manufacturing high-quality plastic extrusion equipments. Including plastic pipe extrusion line, plastic sheet production line, plastic profile extrusion line, plastic plate extrusion line.
Kangju’s MBBR biological filter media production line is designed for continuous extrusion of plastic biofilm carriers used in wastewater treatment systems. The complete line integrates material feeding, extrusion, moulding, vacuum calibration, haul-off and cutting.
The MBBR media production line can be configured according to the required media design, raw material, product dimensions and production capacity. It is suitable for manufacturers producing MBBR media for municipal wastewater treatment, industrial wastewater treatment and biological filtration applications.
MBBR biological filter media are plastic carriers designed to provide a protected surface for biofilm growth in biological wastewater treatment systems. Their structure and surface area help microorganisms attach to the media while wastewater flows through the treatment process.
Kangju’s MBBR production line uses plastic extrusion technology to form continuous media profiles with controlled dimensions. The line combines extrusion, moulding, vacuum calibration, haul-off and cutting into an integrated production system.
The biological filter media making machine can be configured according to the required carrier shape, size, material and production capacity. It is suitable for manufacturers producing MBBR media for municipal wastewater treatment, industrial wastewater treatment and other biological filtration applications.
MBBR biological filter media are plastic biofilm carriers used in moving bed biofilm reactor wastewater treatment systems. The carriers provide surface area for microorganisms to grow and support biological treatment inside the reactor.
The media are manufactured from suitable thermoplastic materials and are designed with internal structures or protected surfaces that support biofilm attachment while allowing water and air to move through the carrier.






Plastic raw materials are fed into the extrusion system through an automatic feeding unit. The feeding system helps provide a stable material supply during continuous production.
The single screw extruder heats, melts and plasticizes the material before pushing it through the extrusion mould. Extrusion conditions can be adjusted according to material characteristics and product requirements.
The extrusion mould forms the required MBBR media profile. The vacuum calibration table then helps stabilize the dimensions and shape of the extruded product during cooling.
The haul-off machine continuously pulls the formed profile through the calibration section at a controlled speed while the product is cooled and stabilized.
After calibration and haul-off, the continuous profile is cut into the required media length by the flying cutting machine. The finished MBBR media can then be collected, inspected and packaged.
Different MBBR carrier designs require different extrusion mould configurations. The mould determines the basic profile, dimensions and internal structure of the media.
Kangju can configure the extrusion mould according to the required MBBR media design, product dimensions, number of cavities and production capacity.
Before selecting the mould, customers should provide the target media drawing, dimensions, material and required output whenever possible. This allows the extrusion system to be matched to the actual production requirements.

MBBR biological filter medias exhibit remarkable efficiency in eliminating BOD, nitrogen, and ammonia. MBBR biological filter medias are exceptionally well-suited for upgrading and renovating sewage treatment plants, as well as for advanced denitrification processes.

For municipal wastewater treatment plants and sewage treatment systems.

For industrial wastewater treatment applications where biological treatment is required.

MBBR media can be used when existing treatment systems need additional biological treatment capacity.

Used as biofilm carriers to provide protected surfaces for microorganism attachment.
