Moving Bed Biofilm Reactor



What is an MBBR?

Moving bed biofilm reactors (MBBR) is a biological technology used in wastewater treatment. MBBRs are suitable for industrial, and municipal, wastewater treatment applications. MBBR's provide pretreatment of wastewater by utilizing biology. These wastewater systems help industrial and municipal plants remove BOD from their wastewater. MBBRs also help the nitrification, and denitrification of wastewater. MBBRs are a great system choice as they are effective and reduce costs.

How do MBBRs work?

MBBR systems consist of large water tanks. Inside these tanks are wastewater and biofilm media carriers. The media provides a protected surface area for the acclimation of bacteria. The bacteria that grow on the media help break down elements of the wastewater. Made of high-density polyethylene, our media carriers have an effective life of over fifteen years. The microorganisms breakdown the wastewater. These microorganisms are then sloughed off of the media and are discharged with the treated water. MBBR systems are ideal for the pretreatment of wastewater streams that contain organics.

Past Project: MBBR Removes More Than 90% of the BOD at Food & Beverage Facility


Potato Product MBBR
  • Project: bioFAS™ MBBR System for Potato Production Plant
  • Industry: Food & Beverage
  • Application: Reduce Biochemical Oxygen Demand (BOD)
  • Application Parameters:

Problem: Potato Products of Idaho needed a robust wastewater treatment system to maintain compliance with the new discharge permit regulations. 

Solution:  bioprocessH2O supplied a bioFAS™ MBBR Equipment Package sized and designed for Biochemical Oxygen Demand (BOD) removal to offset organic loading to the municipal wastewater treatment plant. 

Status/Results:  The bioFAS™ MBBR Treatment System effectively reduces the BOD concentration to meet the effluent discharge requirements.
