moving bed biofilm reactor MBBR carrier

Introduction to Moving Bed Biofilm Reactor (MBBR)

MBBR is an innovative wastewater treatment technology. It uses plastic carriers with a biofilm attached to them. This biofilm is a habitat for bacteria that break down organic matter. The carriers are mobile, so they mix and distribute biomass throughout the reactor.

MBBR is versatile. It can upgrade existing wastewater plants or act as a standalone system. It’s also modular, meaning it can be used for both small- and large-scale projects. Plus, it’s compact and energy-efficient.

The advantages of MBBR don’t end there. It can withstand shock loads, so it works well in unpredictable environments. And, it prevents eutrophication by removing nitrogen compounds. MBBR carriers are the real MVPs of wastewater treatment!

Overview of MBBR Carriers

MBBR carriers are essential in the moving bed biofilm reactor system. They offer a surface for bacteria to form a biofilm, which helps in wastewater treatment. The carriers have a huge surface area for their size, making microbial growth efficient.

The table below presents an overview of MBBR carriers and their key features:

Carrier Type Material Specific Surface Area (m2/m3) Shape
K1 HDPE + Additives 750 – 850 Cylindrical
K3 PVC 500 – 600 Cylindrical
K5 PEHD 350 – 500 Cuboid
BCR Polypropylene 1000 – 1200 Irregular/prismatic

These carriers offer various options for different needs. K1 is made from HDPE with additives, offering the highest surface area and has a cylindrical shape. K3 is made from PVC, with slightly lower surface area but maintains its cylindrical form. K5 has a cuboid shape and moderate surface area, while BCR offers the highest surface area and has an irregular or prismatic shape.

MBBR carriers were first introduced in the late 1980s for wastewater treatment. They revolutionized the industry by boosting biofilm growth in reactors. Over time, these carriers have become popular for their effectiveness and versatility.
