Course Objective

This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.

Course Description

This course is intended for civil engineers, chemical engineers and environmental engineers. Topics included are general information about the MBBR wastewater treatment process; MBBR process design calculations for BOD removal and nitrification, including single stage BOD removal, single stage nitrification, two stage BOD removal and two stage BOD removal and nitrification processes; background information about MBBR denitrification processes; post-anoxic denitrification process design calculations; and pre-anoxic denitrification process design calculations. A sample spreadsheet is included that illustrates the use of a spreadsheet to make some of the calculations discussed in the course.

The overall objective of this course is to provide the attendees with knowledge about the moving bed biofilm reactor (MBBR) process for wastewater treatment and process design calculations for MBBR wastewater treatment. A more detailed list of learning objectives is included in the course document.

At the conclusion of this course, the student will

Know the differences between attached growth and suspended growth biological wastewater treatment processes.
Be familiar with the general configuration and components of an MBBR wastewater treatment process.
Be able to name the six MBBR process configurations discussed in this course.
Be able to calculate the loading rate of a wastewater constituent to an MBBR process (in lb/day and g/day) for specified wastewater flow rate and constituent concentration.
Be able to calculate the required carrier surface area for an MBBR wastewater treatment process for specified SALR and loading rate.
Be able to calculate the required MBBR tank volume for specified carrier surface area, carrier specific surface area, and the carrier fill %.
Be able to calculate the liquid volume in an MBBR tank for known tank volume, carrier volume and carrier % void space.
Be able to calculate the BOD, NH3-N, or NO3-N removal rate for known values of the surface area removal rate (SARR) and design carrier surface area.
Be able to calculate 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.
Be able to use the sample spreadsheet included with the course to make process design calculations for a single stage BOD removal process in either U.S. units or S.I. units.
Be able to use the sample spreadsheet included with the course to make process design calculations for a single stage nitrification process in either U.S. units or S.I. units.
Be able 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.
Be able to make process design calculations for a pre-anoxic denitrification MBBR process, including required tank sizes, estimated effluent concentrations, and alkalinity requirements.

Found this course quite challenging (mostly keeping the terms straight). MBBR is not something used around here and most systems are simple EAUs. As a designer, I probably would not specify one of these units for a client mainly because of limited certified operators in our area. That however may be changing. A thorough course that I enjoyed.

Very good introduction to MBBR design. I do wish you had provided the denitrification worksheet in the Excel file.

Subject is not easy to present in such a short period of time. Spreadsheets were not included, which would have made calculations easier and possibly helped to clarify some of the concepts.

It appeared that in several locations the incorrect conversion from m3 to ft3 occurred (ex page 11, and in examples it had multiply by 3,2808, I believe it should be 35.32) Also example 1 did not specify the specific surface area of the carrier. Other examples gave a value of 600 but the spreadsheet had 500

Thanks for the feedback. Corrections/clarifications are done.

Excellent course. Great information. Excellent information and problems. Test was more difficult since I am not very familiar with this topic, but fair and do-able.

Pretty thorough course, very applicable to my line of work (industrial wastewater treatment). I will likely customize the spreadsheet provided as part of the course for use in our engineering department. A great basis.

I really liked this course as the subject of de-nitrification is of great interest to me (in storm water) and the course actually required a fair amount of calculations and thought. It was ordered like a textbook should be. However a). the spreadsheets for the denitrification process were not included and I don't use Amazon Kindle, b). I don't have 3 screens to page back and forth in the text and c). at least 2 of the references were unavailable at the links provided.
