Practical Planning and Implementation of Biological Nutrient Removal
 
May 7, 2013; 2:30pm ET

120 minutes duration 


This session will feature the following speakers:

·         Ed Kobylinski; Senior Wastewater Process Engineer, Black & Veatch

·         Tracy Hodel; Assistant Public Utilities Director, City of St. Cloud, MN

·         Heather Phillips; Process Engineer, City of Olathe, KS

·         Neil Massart; Process Engineer, Black & Veatch

 

General nutrient guidelines are increasingly being implemented at facilities which have previously had no limits. As plans for these new Biological Nutrient Removal (BNR) facilities are made, years of experience and lessons learned at numerous BNR facilities can be applied to deliver the best possible project for a given situation. This webcast will cover practical planning and implementation considerations through several insightful case studies.  This broad base of case studies will highlight the range of opportunities and challenges associated with planning and implementing nutrient removal. These case studies will be followed by a discussion of the best practices in BNR startup and management of unforeseen startup issues.

 

First, the need to identify site specific challenges and opportunities will be highlighted in Johnson County KS Middle Basin Plant.  Middle Basin acts as a regional biosolids handling facility where an increased sidestream nutrient load creates challenges for an already carbon limited plant.  The next case from St. Cloud MN shows the benefits of involving all stakeholders early in the planning phase and throughout design and construction, incorporating flexibility for future growth and nutrient limits, and reuse of existing assets over new infrastructure. Holistic planning allowed St. Cloud to reduce costs while meeting current and future nutrient limits, eliminating the need for major capital upgrades in the future.  The final case; the Cedar Creek Plant in Olathe KS, requires N and P removal and has an extreme limitation of the influent readily biodegradable COD required to drive BNR.  As the most recent to come online; this case study will highlight the latest BNR design features, as well as the innovative mixed liquor fermenter implemented to overcome the challenging carbon balance. 

 
 

High-Rate Clarification Alternatives

March 26, 2013; 2:30pm ET
120 minutes duration

This session will feature the following speakers:

·         Jeff Neemann; Director of Water Technology, Black & Veatch

·         Paul Hargette; Senior Process Engineer, Black & Veatch

·         James Ostrowski; Senior Process Engineer, Black & Veatch (UK)

·         Victoria Sharp; Water Systems Operations Superintendent, City of Chandler, AZ

·         Gary Witcher; Water Treatment Manager, California Water Service Company

Many utilities are finding it essential to increase treatment capacity and process performance within an existing footprint. Whether the application is for retrofitting an existing facility or for new plant construction, minimizing the plant’s footprint can be a critical factor. This is leading utility managers and engineers to select high-rate clarification technologies that can provide high solids capture efficiency and processing capability within a substantially smaller footprint than conventional sedimentation basins.
 
This session will provide a review of the available options for high-rate clarification technologies, including Actiflo®, inclined plate settlers, and dissolved air flotation. We will review project drivers, including advantages and disadvantages of each technology, for both new construction and for retrofit applications. The session will include an international perspective, highlighting lessons learned from around the globe, including areas that have traditionally had limited footprint availability. Two case studies will be presented, one from a utility that implemented the Actiflo® treatment process and the second from a utility that implemented plate settler technology. The case studies will discuss the drivers for why the given technology was selected, how the technology was implemented and the impact to plant operations.
 
Co-Digestion of High Strength Wastes

December 4, 2012; 2:30pm ET
120 minutes duration

This session will feature the following speakers:

·         Trish Scanlan; Director, Residuals Treatment Process Group, Black & Veatch

·         Bob Wimmer; Wastewater process Specialist, Black & Veatch

·       George Bevington; Former Manager, Gloversville-Johnstown Joint Wastewater Treatment              Facility; Consultant, Gerhardt LLC


As wastewater treatment plants transition in role and function into resource recovery facilities, energy recovery from anaerobic digester gas is providing opportunities for both energy independence and revenue generation.  In addition to utilizing the carbon available from wastewater solids, many facilities are accepting high strength waste for co-digestion to increase gas production and in some cases to reduce the loading to aeration basins. Co-digestion utilizes existing capacity in anaerobic digesters and engine generators, often with minimal investment of additional capital.  However; co-digestion of high strength waste requires careful planning, a shift in the traditional business plan of a POTW, and careful monitoring by skilled operators. 


This presentation will discuss the components of implementing a successful high strength waste co-digestion facility including the business analysis, required equipment, and impacts to the liquid side and solids stream.  Several case studies will be discussed, focusing on the challenges of the supply of and competition for high strength waste.  Finally, the superintendent of the Gloversville-Johnstown Joint Wastewater Treatment Facility in New York will discuss the day to day operational challenges of a successfully operating co-digestion facility.  Gloversville-Johnstown is in the heart of Greek Yogurt country where co-digestion facilities are producing more than 90% of the plant’s power supply.

 
 
 
 
Meeting Nutrient Limits, Part 1 of 2:
Biological Nutrient Removal
 
June 5, 2012; 2:30pm ET
120 minutes duration
 
 

This session will feature the following speakers:

·         Brian Thompson (EPA Region 5 - Water Quality Standards Program)

·         Stephen M. Jann (EPA Region 5 - NPDES Programs)

·         James Barnard (Black & Veatch - Global Practice and Technology Leader)

·         Heather Phillips (Black & Veatch - Wastewater Process Engineer)

·         Joseph Lockler (Charlotte-Mecklenburg Utilities - WWTP Manager)

 
Over the past several decades, as the understanding of the adverse impacts of nitrogen and phosphorus loadings on waterways has been better defined, increasing measures have been taken to limit these nutrient loadings.  Regulations have been and continue to be developed that impose numerical nutrient discharge limits on POTWs discharging to nutrient impaired waterways.  Nutrient discharge limits range from ultra low concentrations that require limit of technology (LOT) or enhanced nutrient Removal (ENR), to more moderate limits that can be achieved by conventional biological nutrient removal (BNR).  In the first part of our two-part series on nutrient removal, we will focus on BNR at levels of treatment which have been successfully applied to numerous treatment plants in the United States for the past 20 years or more.  Our second BNR session, scheduled in late 2012, will focus on ENR and LOT nutrient removal.    

 

This Insight H2O session will open with a discussion of the current regulatory approach to nutrient removal.  The discussion will include water quality perspectives and information on how water quality based goals are converted into end of pipe NPDES permit limits.  This will be followed by a discussion on the biological fundamentals which make BNR the most cost effective nutrient control strategy, and the options available to upgrade existing treatment works to BNR.  The application of mathematical models and sampling procedures for BNR design and operation will also be covered.  Lastly there will be presented a case study describing operations at the McDowell Creek WWTP in Charlotte, North Carolina, which has been successfully controlling nutrients since 1997 when its first numerical limits of 10.0 mg/L N and 1.0 mg/L P were imposed on the facility.  This facility also has mass nutrient discharge limits that have required higher levels of removal as plant flows increased over the years. The case study will focus on operation during the process upgrades to plant, how these were successfully performed while not interrupting treatment plant service, and nutrient removal lessons learned.

Delivery and Financing Options for Water and Wastewater Projects 
May 8, 2012; 2:30pm ET
120 minutes duration
 
 

This session will feature the following speakers:

·         David Kinchen (Director of Water Expanded Scope Projects; Black & Veatch)

·         Larry Wyeno (Engineering Administrator; City of Longmont, CO)

·         Tami Ray (Director of Management Consulting; Black & Veatch)

·         Eric Zampol (Director of Infrastructure Banking; BMO Capital Markets)

Municipal water providers are facing increased pressure to provide the same quality of safe drinking water and wastewater treatment solutions with fewer resources and at a lower cost. In many cases time constraints place additional pressure on Owners as they seek best-value solutions and project funding.  This complex set of objectives and limitations often times requires that a more complete suite of project delivery and financing options be given consideration.   

 

This presentation discussed an overview of various delivery and financing methods and the key features for consideration in their application to your project.   Delivery options discussed include the traditional design-bid-build, as well as the less traditional design-build approaches, construction manager-at-risk (CMAR), design-build-operate-finance (DBOF) and public-private partnerships (P3).  A case study was presented demonstrating how the City of Longmont, Colorado successfully used the progressive design-build method to deliver a major water project.  Available funding resources and methodologies were discussed, including those that provide financing for P3 initiatives.  An example of how these funding methodologies were successfully applied to over 30 systems by the Lower Colorado River Authority was examined.

 
 
Integrated Planning for Water Utilities  
 April 3, 2012; 2:30pm EST
120 minutes duration
 
This session featured the following speakers:
  •  Jeff Henson; Director of Water Resources, Black & Veatch
  •  Klint Reedy; Senior Water Resources Engineer, Black & Veatch   
  •  Dr. Fred Bloetscher; Associate Professor, Florida Atlantic University
  •  Steve Hellman; Chief Financial Officer, Aurora (Colorado) Water

Water utility managers are facing an ever-increasing set of goals and constraints that affect how safe and sufficient water can be supplied to their customers in a cost effective and sustainable manner. The traditional elements of supply, treatment, and distribution must be balanced with stakeholder involvement, environmental stewardship, and financial sustainability. In most metropolitan areas, there is also an increased emphasis to look at water holistically, with combined assessments of regional water supplies along with wastewater and stormwater systems. Water planning must address the uncertainties associated with changes in projected demands due to conservation and climate variability and also must consider the full range of available supplies including reuse, desalting, and rainwater capture. All of this emphasizes the need for water utilities to utilize more comprehensive and sophisticated tools for planning.

This presentation provides a valuable overview of the integrated planning process and the benefits to be derived through its application with particular emphasis on water supply, systems planning and financial sustainability. The water supply planning component will address uncertainties associated with climate variability and increased competition for available supplies and demonstrate how progressive utilities are using a portfolio of supplies to provide greater resilience in the face of future uncertainty.

Real world utility perspectives will be presented to illustrate the measures taken by utilities integrating their planning with operational and financial objectives. We will focus on utilities’ operational decision making to incorporate new sources and water of different quality into their system. One utility manager will share a focus on maintaining a strong financial balance sheet while addressing reduced water sales due to aggressive conservation practices and significant needs for capital expenditures to diversify sources of supply.

 
 
 
 
21st Century Solutions for Water Reclamation  
 June 1, 2011; 2:30pm EDT
120 minutes duration
 
This session featured the following speakers:
  •  Cindy Wallis-Lage (Managing Director, Technical Solutions; Black & Veatch)
  •  Vasu Veerapaneni (Senior Process Engineer; Black & Veatch)   
  •  Mr. Wah Yuen Long (Director of Water Reclamation Plants; Singapore PUB)
  •  Mehul Patel (Groundwater Replenishment System Program Manager; OCWD)
The ever-increasing demand for potable water coupled with stressed fresh water sources is forcing utilities to manage total water solutions now more than ever before. This involves developing an environmentally sustainable water supply portfolio that meets demands for potable, industrial and agricultural use, and preserves our natural waterways. This complex and often competing set of objectives is driving utilities to look more closely at water sources that were previously considered impaired. Successful incorporation of these sources into a water supply portfolio requires a solid understanding of diverse issues including treatment process selection, nutrient and micro contaminant removal, management of waste streams, optimization of energy consumption, and managing public perception.

This presentation will discuss the major aspects of implementing water reclamation including the drivers for reuse, the multiple approaches to selecting treatment processes, and a look at what two of the leading utilities in this field are doing; Singapore PUB and Orange County, CA (OCWD). As the national water agency, PUB is responsible for the collection, production, distribution and reclamation of water in Singapore. OCWD operates the world’s largest water reuse facility, and is currently expanding its facility from 70 to 100 MGD involving MF/UF, RO, and UV/H2O2 technologies.

    What's on the Drawing Board for Wet Weather Management?
     March 3, 2011; 2:30pm EST
    120 minutes duration
     
    This session featured the following speakers:
    Wastewater utilities across the United States continue to move forward with programs aimed at controlling wet-weather overflows while maintaining or improving the effluent quality from their facilities. Many factors complicate the challenges faced by these programs, including:
    • The current economic slowdown along with aging infrastructure needs and other water quality concerns and regulatory drivers (nutrients, microconstituents, etc.) have increased the need for utilities to further prioritize capital expenditures and more highly scrutinize their potential benefits.
    • Significant regulatory uncertainties have raised concerns about the lack of comprehensivenational policies to sustainably address wet-weather management issues at the watershed level.
    • Influent characteristics are much different for wet-weather flows than during normal dry-weather conditions, and water quality professionals have long understood that conventional treatment processes are susceptible to upsets from wet-weather flow events.
    •  The wet-weather characteristics and behavior of each collection system, treatment plant and receiving waters are unique and complex. To effectively solve these problems for each watershed, planners and designers need a wide assortment of alternatives, many of which are beyond the scope of existing conventional POTW standards.
    Jim Fitzpatrick spoke on treatment strategies and technologies, focusing on state-of-the-art approaches that have been implemented in the last decade or so along with recent designs and pilot trials and perspectives on potential regularoty disconnects.
     
    As co-chair of the WEF Government Affairs Wet Weather Workgroup and managing engineer for many of Johnson County Wastewater’s I/I reduction projects, Dan provided insight into collection system issues, sustainable infrastructure practices, and the implementation realities for medium-sized suburban wastewater utilities with separate sanitary sewers.
     
    As NACWA president and St. Louis MSD executive director, Jeff spoke on policy issues and their implications, particularly for large urban wastewater and stormwater utilities with both separate and combined sewers.

    ·Pat Sullivan (Engineering Manager, Black & Veatch)
    ·Adam Turner (Project 7 Water Authority, Colorado)

    The global drive for renewable energy has not only motivated power producers to invest in hydropower, water and wastewater utilities are also seizing upon the opportunity to take advantage of hydropower in their systems. The adoption of hydropower in water and wastewater systems typically takes the form of small hydropower units (less than 5 MW), and has gained momentum in part thanks to federal, state, and local financial incentives and regulations. These incentives coupled with rising power costs result in attractive financial metrics for owners.
     
    The discussion will focus on emerging trends in small hydropower for water and wastewater utilities including technologies, financial incentives, licensing concerns, hydropower opportunities, and one utility’s recent small hydro implementation experience. The Webcast will also discuss basic hydropower terminology to facilitate communication between water producers and the hydropower industry. Finally, the Webcast will highlight the benefits of installing hydropower in existing water and wastewater systems including offsetting power consumption, selling power back to the grid, and improving community and stakeholder relations through sustainability.
