Biological Wastewater Treatment III - MBR Processes

COURSE NO: C02-067
PDH CREDIT: 2
Biological Wastewater Treatment III - MBR Processes
Course Highlights

This online engineering PDH course provides a discussion of process design calculations for the membrane module used in an MBR (membrane bioreactor) system, for an MBR aeration tank designed to provide BOD removal and nitrification, and for a pre-anoxic tank to go with an MBR BOD removal and nitrification system.

 

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

 

The MBR process uses an aeration tank similar to those used in conventional activated sludge processes, combined with membrane filtration as a replacement for secondary sedimentation.  This combination can produce a very high quality effluent, typically with a more compact reactor than conventional activated sludge, but requires a higher rate of aeration than conventional activated sludge in order to keep the membranes from fouling.  The current typical MBR process configuration uses a membrane module submerged in the aeration tank.

 

This 2 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 MBR wastewater treatment process and be able to make typical process design calculations for an MBR process.
Learning Objectives

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

  • Familiarizing with the components of and general configuration of an MBR wastewater treatment process
  • Understanding the advantages and disadvantages of an MBR wastewater treatment process in comparison with a conventional activated sludge process
  • Knowing the type of pretreatment typically required for an MBR wastewater treatment process
  • Carrying out process design calculations to determine the required membrane area, membrane module volume and scouring air flow rate
  • Carrying out process design calculations for a BOD removal/nitrification MBR process in order to determine the required aeration tank volume, sludge wasting rate, air flow rate, and alkalinity addition
  • Carrying out process design calculations for a Pre-Anoxic Denitrification MBR process in order to determine the required pre-anoxic tank volume, the reduced oxygen/air requirement, the reduced alkalinity requirement, the anoxic tank mixing power needed, and the sludge wasting rate
