Biological Wastewater Treatment II - MBBR Processes

COURSE NO: C04-045
PDH CREDIT: 4
Biological Wastewater Treatment II - MBBR Processes
Course Highlights

This online engineering PDH course provides a discussion and detailed examples of process design calculations for a single stage BOD removal MBBR (moving bed biofilm reactor) system, a two-stage BOD removal MBBR system, a single stage tertiary nitrification MBBR system, a two-stage BOD removal/Nitrification MBBR system a post-anoxic denitrification MBBR system and a pre-anoxic denitrification MBBR system.

 

This course is Part II of a three-part series. The other two courses in this Biological Wastewater Treatment series are about activated sludge processes (Part I) and Membrane Biofilm Reactor (MBR) processes (Part III).

 

The MBBR process is an attached growth process that uses plastic carriers to provide a surface on which biofilm grows.  The MBBR process doesn’t require sludge recycle, because the biomass remains in the system attached to the plastic carriers.  The required reactor size for an MBBR process is typically significantly smaller than that for an activated sludge process treating the same wastewater flow, or for other common attached growth processes like the RBC or trickling filter. It can be used for BOD removal, biological nitrification, biological denitrification, and biological phosphorus removal.

 

This 4 PDH online course is intended primarily for civil engineers, environmental engineers, and chemical engineers. After completing this course you will be familiar with the general components and configuration of an MBBR wastewater treatment process and be able to make typical process design calculations for an MBBR process.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding the differences between attached growth and suspended growth biological wastewater treatment processes
  • Familiarizing with the components of and the general configuration of an MBBR wastewater treatment process
  • Calculating the loading rate of a wastewater constituent to an MBBR process (in lb/day and g/day) for a specified wastewater flow rate and constituent concentration
  • Calculating the required carrier surface area for an MBBR wastewater treatment process for a specified SALR and loading rate.
  • Calculating the required MBBR tank volume for specified carrier surface area, carrier specific surface area and carrier fill %
  • Calculating the liquid volume in an MBBR tank for known tank volume, carrier volume and carrier % void space
  • Calculating the BOD, NH3-N, or NO3-N removal rate for known values of the surface area removal rate (SARR) and design carrier surface area
  • Calculating an estimated effluent BOD, NH3-N or NO3-N concentration based on known values of the appropriate loading rate, estimated removal rate, and design wastewater flow rate
  • Learning how to make process design calculations for a post-Anoxic denitrification MBBR process, including required tank sizes, estimated effluent concentrations, alkalinity requirement and carbon source requirement
  • Learning how to make process design calculations for a pre-Anoxic denitrification MBBR process, including required tank sizes, estimated effluent concentrations, alkalinity requirements
