8:15 – 9:15 a.m.
A Battle to Be the Best: A Comparison of Two Powerful Sidestream Treatment Technologies: Post Aerobic Digestion and Annamox David W. Oerke, P.E. Senior Principal Technologist, CH2M
Post Aerobic Digestion (PAD) and Anaerobic Ammonium Oxidation (Anammox) are both sidestream treatment technologies which are excellent options for the reduction of nitrogen recycled back to the liquid stream without the need for supplemental carbon or alkalinity. However, the achievement of this goal is where the similarities between the two technologies end. Since PAD and Anammox sidestream treatment technologies target different sidestream flow streams (PAD targets digester effluent while Anammox targets the filtrate or centrate produced from dewatering), different mass and percent removals are predicted by simulation results. However, the model results confirm that both the two sidestream treatment technologies evaluated can remove significant amounts of constituents from the filtrate compared to the baseline (no sidestream treatment) and can achieve similar effluent quality.
 
9:15-10:15 a.m.
WWTP Energy Management Solutions and Case Studies
David W. Oerke, P.E. Senior Principal Technologist, CH2M
Using case studies, the presentation will demonstrate how utilities across the United States are implementing comprehensive and scalable energy management strategies to achieve cost savings, price stability and renew aging infrastructure. The improvements are also helping the utilities address the challenges of today’s times such as pollution, global warming and resource depletion.  This presentation will expand the knowledge in the growing area of energy conservation and bioenergy project development and implementation. The paper will be useful to wastewater utility owners, operators and the community in general to become more aware about wastewater’s sustainability potential.
 
10:15-10:30Break
10:30 a.m. – 11:30 a.m.
Treatment Process Intensification for Sustainable Biological Nutrient Removal
Jose Jimenez, Director of Water Technology, Brown and Caldwell
Nutrient removal systems have been successfully operated for decades. However, the wastewater industry is currently facing dramatic changes, shifting away from energy intensive wastewater treatment towards low-energy, sustainable technologies capable of achieving energy positive operation while recovering important resources. As a response to this dramatic change in the wastewater industry, researchers are working alongside with practitioners and operators to develop and implement innovative solutions to support the needs of our industry. Therefore, this presentation intends to provide an overall summary of technologies currently being adopted by Utilities to maximize treatment capacity and performance while reducing O&M and capital investments.
 
11:30 a.m. – 12:30 p.m.
Advances in Nitrogen and Phosphorus Removal at Low DO Conditions
Jose Jimenez, Director of Water Technology, Brown and Caldwell
Simultaneous nitrification-denitrification (SND) has been referred to as a biological process for nitrogen removal where nitrification and denitrification occur concurrently in the same aerobic reactor. SND facilities have been shown to remove 80 to 96 percent nitrogen without additional carbon and alkalinity. Carbon availability and bulk dissolved oxygen concentrations were found to be important process parameters for SND activity. Data suggest that a chemical oxygen demand-to-nitrogen (COD:N) ratio of at least 10.0 is required to achieve significant denitrification; and an optimum bulk DO concentration ranging from approximately 0.3 milligrams per liter (mg/L) to 0.7 mg/L appears to maximize SND activity. Therefore, this presentation intends to provide an overall summary of state of the art knowledge on low DO operation and how this impacts N and P removal in WWTPs.
 
12:30 p.m. – 1:15 p.m.  Lunch
1:15 p.m. – 2:15 p.m.
Biological Nutrient Removal Operational Awareness
Steve Walker, Ops Assistance Group Leader, Carollo Engineers
This session focuses on the interactions that influence and occur within the activated sludge process that can affect nutrient removal. Pressures covered include volatility, temperature, pH, alkalinity, dissolved oxygen, and solids inventory control. Data acquisition locations and data analysis are discussed to highlight typical errors.Real examples of each are provided to allow the operators to compare the topics to their own work and facilities.
 
2:15 – 3:15 p.m.
Contract Strategies for Managing Compliance Risk During Construction 
John Luna, P.E., Engineer/Construction Manager, Carollo Engineers
As operators, most of you have had to operate treatment, collection, or distribution systems through active construction.  Most of the time, the success of these projects revolves around the relationships and intentions of the Contractor and Owner.  However, good design practices and Contracts that are organized around maintaining treatment capacity can ease the difficulties often encountered during construction.  In this presentation I will provide examples of the tools and strategies for Contracts that provide the contractor and owner/operator with project definition, boundaries, and tools for coordination during construction in operating facilities.
 
3:15 - 3:30 p.mBreak
3:30 – 4:30 p.m.
Online Instrumentation for Wastewater Treatment
Gary Girolimon, PE, President, Ted D. Miller Associates, Inc. 
Online instrumentation is being deployed and used more and more for monitoring and controlling municipal wastewater treatment plants.  Suspended solids and dissolved oxygen sensors were some of the first online instruments used in controlling activated sludge plants.  Nutrient removal dictated the use of online nutrient sensors for ammonium and nitrates among other sensors.  An overview of some of the most recent online instrumentation is provided along with how these analyzers are used in wastewater plant operations.
