Biological Wastewater Treatment II - MBBR Processes
PRICE GROUP WEBINAR
Webinar Title: Biological Wastewater Treatment II - MBBR Processes
Webinar No: C04-201W
PDH Credit: 4
Presenter: Harlan Bengtson, Ph.D., P.E.
Time: From 12:00 PM to 4:00 PM ET
This engineering online PDH live webinar will establish, through slides, discussions and detailed examples of process design calculations for the following types of MBBR systems: single stage BOD removal, two stage BOD removal, single stage nitrification, two-stage BOD removal/nitrification, post-anoxic denitrification, and pre-anoxic denitrification.
The MBBR (moving bed biofilm reactor) process is an attached growth process that uses plastic carriers to provide a surface on which biofilm grows. The plastic carriers are kept suspended in the aeration tank by an aerator for an aerobic process or by mechanical mixing for an anoxic or anaerobic process. 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 live webinar is intended primarily for civil, environmental and chemical engineers. After completing this webinar, 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.
This live webinar is intended to provide you with the following specific knowledge and skills:
- Knowing the differences between attached growth and suspended growth biological wastewater treatment systems
- Familiarizing with the components of and general configuration of an MBBR wastewater treatment system
- Learning how to calculate 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
- Learning how to calculate the required carrier surface area for an MBBR wastewater treatment process for a specified SALR and loading rate
- Learning how to calculate the required MBBR tank volume for specified carrier surface area, carrier specific surface area, and carrier fill %
- Learning how to calculate the liquid volume in an MBBR tank for known tank volume, carrier volume and carrier % void space
- Learning how 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
- Learning how 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
- Understanding how to make process design calculations for a post-anoxic denitrification MBBR process, including required tank sizes, estimated effluent concentrations, alkalinity requirements, and carbon source requirements
- Understanding how to make process design calculations for a pre-anoxic denitrification MBBR process, including required tank sizes, estimated effluent concentrations, and alkalinity requirements

At this point, you will need to log in to your account, or register if you don’t have one yet, to complete your purchase. (The Log in/Register links are located at the top right corner of the screen.) Following purchase, you will immediately receive two emails: one confirming your registration with a receipt of webinar purchase and the other providing you with instructions on webinar access and completion. Subsequently, you will also receive reminder emails with the same instructions 24 hours and 2 hours prior to your scheduled webinar. You can also download these instructions from your account at anytime.
We recommend that you register for any webinar ahead of time, although you can still register online up to the start time of the webinar. If you need any assistance with last minute webinar registrations, please contact us at 877-322-5800.
From the webinar access and completion instructions that you receive, you will be provided with a link to access the webinar platform from your computer to view and listen in to the webinar. Therefore, to get connected, you will need a computer with high-speed internet as well as microphone and speakers capabilities. We recommend using a headset connected to your computer for enhanced audio quality.
Alternatively, if your computer is not equipped with a microphone and speakers, you need to dial in using a phone line. From the webinar access and completion instructions, you will be also provided with a dial-in number to join the webinar and listen in. Furthermore, you will be provided with a link to download the webinar handout, or you can do directly from you account, in the event you are unable to view the webinar on your computer screen.
Regardless of the connection method used, you will have the opportunity to interact with the instructor at the appropriate times either way. We recommend that you connect to the webinar approximately 10 to 15 minutes prior to the scheduled start time.
Following attending the webinar, you need to return to the CED Engineering website and login to your account to complete and submit your feedback form.
Following submission of your feedback form, we will email you your Certificate of Completion. You can also download your Certificate of Completion instantly, or at anytime, directly from your account. This is where all your PDH records are kept for your convenience at all times.
