JTAC Presentation

Biological Nutrient Removal 101

Thursday, May 18th, 2017

Registration

 

Description:

Many wastewater treatment facilities are being faced with treatment requirements for nitrogen, phosphorus, and even selenium, and the number increases every year. Generally, the most cost effective approach for treating these contaminants is through biological processes. This presentation will address the basics of biological nutrient removal processes and their incorporation into wastewater treatment facilities. In part, the presentation is intended for those who may not need to be “experts” in treating wastewater to remove nutrients, yet would benefit from an understanding of how the processes work (e.g., utilities managers). In addition, this presentation will be of value for recent graduating engineers who learned the theory during school, but would like to get a better “feel” for biological nutrient removal. It will also be beneficial for operators who run one of these systems and would like a better understanding of how and why they do what they do.

 

Speaker:

Steve Polson, P.E., Chair of JTAC. Steve is a senior water and wastewater engineer with CH2M. His practical experience with biological nutrient removal began in the early 1990’s, when he served as a co-author for the book “Phosphorous and Nitrogen Removal from Municipal Wastewater, Principles and Practice”, along with Daigger, Jenkins, Eckenfelder, Barnard, and Stensel, among others, published in 1991. Since that time he has presented on the topic in training sessions for operators (Leadville, Englewood), and he received (along with Glen Daigger and Terry Anderson) the Philip F. Morgan Medal from the Water Environment Federation in 1996 for developing a unique operational approach to improving biological phosphorous removal at a wastewater treatment plant in Colorado.

Registration:

JTAC Registration has changed! Please note that, since February, registration and payment for JTAC luncheons are handled on line. A link is provided in the announcement that can be reached through the committee’s webpage: JTAC Web Page . Registration will no longer be accepted at our e-mail address as in the past. Registration may be made for a single attendee or for multiple attendees in a party. It will still be necessary to check in at the luncheon. Lunches will be based on the head count per the registration site. Please do not attempt to show up without registering in advance. If you are unable to pay on line, please contact Steve Polson (720-286-5376, steve.polson@ch2m.com) to make arrangements for paying with check or cash.

The registration deadline for this event is May 17th at 10:00 AM MST. Please be aware that with the new registration procedure, late registrations will not be accepted as in the past. This will enable us to avoid having to purchase extra lunches to allow for potential late comers.

Check-in is from 11:30 am to 12:00 pm. The presentation will begin shortly thereafter. Registration fees are $20 for AWWA or WEF members, $25 for nonmembers, and $15 for Students and Retired Members.
