Event Description
Water resource recovery facilities (WRRFs) face increasingly stringent nutrient limits. Traditionally, WRRFs have employed energy-intensive biological methods for nitrogen removal and combined biological and chemical techniques for phosphorus removal, and often require costly external carbon sources and significant operational expenses. The partial-nitritation anammox (PNA) pathway has shown potential for mainstream deammonification to reduce carbon substrate, energy, and alkalinity consumption compared to conventional nutrient removal. However, over the past 10 years, several implementation challenges related to “out-selection” of nitrite-oxidizing organisms (NOB) were uncovered. As a more feasible and easier-to-control alternative, the development of the PdNA pathway was pursued. Likewise, PdNA has the potential to help WRRFs meet nutrient limits while also improving efficiency and reducing energy consumption, carbon emissions, sludge production, and overall costs. PdNA provides a number of process intensification opportunities:
1. It enables redirection away from the biological reactor because it requires a fraction of the carbon for nitrogen removal resulting in reduction in BNR footprint.
2. It allows operation near the minimum SRT without introducing additional risk because of its ability to remove ammonia anoxically via anammox bacteria resulting again in further reduction in tank volume need and significantly less aeration.
3. It uses carriers for selective anammox retention which allows for more compact reactor design.
4. It integrates the PdNA and bio-P processes, which will offer the simultaneous removal of phosphorus and nitrogen in the same reactor and minimize the reliance on external carbon.
This presentation will discuss the development of PdNA and its potential to significantly reduce operational and capital costs for nitrogen removal upgrades. The presenter (Jose Jimenez) will cover the concepts, lessons learned from two major and leading utilities in this field, applicability in the general sense, and specific applications for utilities specially under the anticipated TN discharge requirement.

Luncheon Format and Location:
This month’s luncheon will be held virtually. Sorry, you must bring your own lunch. 😊 Instructions on how to register are in the next paragraph. The presentation will begin at 12 noon on the above date (Mountain time, of course). The presentation will be broadcast using Microsoft Teams. Folks who have registered for the luncheon will receive an email the day before with a link to the meeting. Please be sure your microphone is muted, and camera turned off when you join the meeting. The first is obvious and the latter is to reduce bandwidth required. At the end of the presentation, we will hold a Q&A session. For Q&A, please post a message in the Chat window that you have a question, and Steve will call on folks in order. You don’t have to state your question in the Chat area, but you can if you want. Otherwise just turn on your microphone when Steve calls on you.
Registration:
A registration fee of $10 is being imposed for all attendees who are a member if either RMWEA or RMSAWWA. Non members are assessed a registration fee of $15. These are reduced from our typical registration amounts to reflect the online nature of the event. Registration and payment for TAC luncheons will be handled at: TAC Registration . Registration may be made for a single attendee or for multiple attendees in a group. It is requested that each individual in a group either register individually or are included in the count for a group registration, and that multiple parties are not partaking in the presentation without registering. If for some reason you are unable to register online, please contact Steve Polson (303-748-0931), or at steve.polson@jacobs.com, to arrange for paying with check or cash.
The registration deadline for this event is Wednesday, April 17, at COB. We will send out the link for the luncheon to the email addresses per the registration site by the end of the day on Wednesday. If you registered a group, please pass along the link to the members of your group. Please note the Teams program does not need to be installed on your computer to participate. When you click the link provided in the email, an option to participate through your browser is offered. There will also be a call-in number, but it is hoped that nobody is forced to do that, as you will only receive the audio. If you registered but do not receive the email on Wednesday, please call Steve Polson (303-748-0931) on Thursday morning to determine how to get you the link.
The program will start at 12 noon sharp. Please be sure and connect before 12 noon to avoid missing anything.
