FALL 2012 inside this issue by David Laliberte, Program Chair SEDA/AMTA Key Largo Workshop The SEDA/AMTA workshop in Key Largo was a rousing success despite the efforts of Hurricane Sandy to rain on everybody’s parade. The theme of the conference was “Reducing Costs at Membrane Plants” which attracted SEDA/AMTA operators, plant managers, consultants, and manufacturer’s representatives. It is a topic on the minds of many and the presentations were selected to appeal to a wide range of members. By noon on Wednesday registrations reached 109 which demonstrated a wide interest from the industry on this topic. John Potts and Bob Oreskovich, the SEDA and AMTA workshop co-chairs, opened the workshop on Wednesday morning. Greg Turman moderated the morning session, “Energy Costs and How to be More Efficient” which included presentations by Larry Smith, Jeff Bergman, Harold Fravel, Mark Miller, Ben Movahed, Phil Locke, and Ryan Popko. Steve Messner moderated the afternoon session which began with a presentation from Ray Simokubo of Florida Keys Aqueduct Authority (FKAA) on their Florida City water treatment plant. After the presentation we all piled into buses and drove north to Florida City for a tour of the facility. This water plant includes lime softening treatment of shallow aquifer groundwater and reverse osmosis treatment of brackish Floridan Aquifer water. Many thanks to the good people of the Florida Keys Aqueduct Authority for being our host utility and opening up their Florida city facility to so many visitors. Wednesday evening we boarded buses again to Gilberts Resort where we embarked on the Island Time vessel for a really enjoyable two hour networking event. The Island Time vessel was spacious and accommodated all of us very well. Despite Sandy knocking at our door, the captain found calm waters and nobody was seen seasick. Sunset occurred just before docking which demonstrated Sandy was not going to stop us from a planned event. We all had plenty of time to network, catch up with people we have not seen in a while, and get answers to the questions which troubled us the most. Chris Owen moderated the morning session, “Plant Innovative Alternatives”, which included presentations by Glenn Dunkelberger, Coley Ali, Amanda Barnes, David Brown, Julia Nemeth-Harn, and Mike Liggins. After another sumptuous lunch overlooking the now angry Florida Bay, David Brown moderated the afternoon session “Optimizing Plant Costs & Operation” which included presentations from Bob Oreskovich, Matthew Charles and Chaparro, and Jim Andersen. The workshop was put together very well, as usual, by the people at TEAM. On-site were Janet Jaworski, Alie Griffin, Judy Widmeier and Marilyn Medlock.

2 RECOVERY ZONE

Message From The PresidentDear SEDA Membership,

I would like to wish all of our members a happy and healthy holiday season. We have had a very productive year: seven

technology transfer workshops, spring symposium, two Membrane Operators Certification (MOC) Schools and two

joint events with American Membrane Technology Association (AMTA).

We have launched the new SEDA webpage to better communicate with our members and provide immediate postings

of activities and happenings within the organization. We are eager to receive feedback from you on the new website.

Our awards committee has modified our Plant of the Year applications to allow parity with respect to the utility production

capacity. The award is now separated into two categories, larger utilities producing 5 million gallons per day (MGD)

or more and smaller utilities producing less than 5 MGD. Our awards committee is looking for your submission by the

beginning of February 2013. Please visit the webpage for the on-line application forms.

SEDA membership has continued to grow steadily with membership approaching 800 members. We are continuing to

grow both in Florida and the nearby states. As we grow, I would like to honor our long-time members while welcoming

our new members into one of the strongest Membrane Operator Associations in the country.

As I stated earlier, our MOC and Technology Transfer Workshop Committees have been very busy planning events for our

members. We are very excited about the upcoming year and want your input on locations and topics for our technology

transfer workshops. Our MOC School has been divided into two modules to better serve our members’ schedules. We are

also working with other Membrane Operator Associations to provide training modules three and four to complete the four-

module course. We have scheduled the first sessions with the revised modules for this month.

We are gearing up for our Spring Symposium at the Delray Beach Marriott June 16 – 19, 2013. Please mark your

calendar and look for the program entitled “Membrane Rising” early next year.

Our legislative committee is looking for members to join this group. We are looking

for articles on legislative activity to publish in our newsletter and post on our webpage.

If you have an article you would like to share with other members, please contact our

Legislative or Newsletter Chair.

Finally, I would like to thank everyone for your support. I am looking forward to

another productive year for SEDA. Please feel free to contact me or any other Board

Member with your thoughts and suggestions on how we can make SEDA a stronger

organization. David M. Laliberte

County. Delray Beach has been awarded the status “All American City” and offers a lot of shopping, dining, and nightlife wrapped up in a very pleasant small city atmosphere. The networking event will be a dinner cruise on the Intracoastal Waterway which will provide an great opportunity to talk with other plants and exchange ideas on how to correct each other’s issues. The symposium theme is “Membranes Rising – What’s New in Membranes”. The program will have a focus

on UF/MF in both wastewater and water treatment applications; advancements in membranes that have led to lower operating costs, less frequent cleaning, and production of better quality drinking water; and disinfection byproduct new rules and issues. Sponsorships and exhibit opportunities will be available. Attendees will be able to get CEU’s and will have an opportunity to interact with individuals dedicated to membrane applications. The SEDA Spring Symposium is always well attended and gives members a chance to learn , have fun and take advantage of a nice location.

The City of Clearwater will expand production capacity at RO Plant #1 from 3 MGD to 4.5 MGD. Plans include membrane replacement, addition of an arsenic adsorption system, re-use of backwash from existing Dual Media filters and iron solids decanting, settling and disposal. Increased production capacity will be achieved by reconfiguring the raw water flow to treat only the portion of water needed for RO processing through the existing Dual Media filters and bypassing the remainder through the arsenic adsorption system for increased blend water capacity. In

addition, the original membranes are to be replaced with high-flux membranes to increase permeate production. Other improvements include demolition of an existing 5 MGD ground storage tank built in 1965 and replacement with (2) 3 MGD ground storage tanks. In addition the concentrate from RO Plant #1 will be pumped offsite to be used as feed water at RO Plant #2, which is currently under design, thereby creating beneficial use of the concentrate, and reducing the load on the City’s sanitary sewer system. The consultant is CDMSmith and completion is expected in late 2013.

One of the most requested changes to the MOC School through the years has been to divide the course into a beginner’s course and an advanced course. While I would not characterize the course that way, Module 1 is what you need to know and Module 2 builds on that foundation. All of the chapters have been reviewed and freshened up by our expert group of instructors and the SEDA Board of Directors. The modules are now scheduled as 2 ½ day courses including a final exam. As stated in the last newsletter we held our last full week school in Palm Coast in May of this year. We are finishing up the final review of the Module 1 and Module 2 courses for publication and delivery at Pompano Beach in the first week of this December. As early as next spring we will add Module 3 to our course lineup and it will cover low pressure membrane (MF/UF) applications. This module is currently in development by our sister affiliate, the South Central Membrane Operators Association (SCMA) 2012 is turning out to be a year of very positive changes for our organization and its membership.

The 2013 spring symposium will be held on June 16 through June 19 in Delray Beach. The host facility is the Marriott Hotel located in the beautiful Delray Beach in southern Palm Beach County. Delray Beach has been awarded the status “All American City” and offers a lot of shopping, dining, and nightlife wrapped up in a very pleasant small city atmosphere. The networking event will be a dinner cruise on the Intracoastal Waterway which will provide an great opportunity to talk with other plants and exchange ideas on how to correct each other’s issues.

The City of Port St. Lucie’s Utility Department hosted a recent Technical Transfer at their Prineville RO WTP which was sponsored by Hydranautics and CSM. The event was a great success with 26 attendees ready to engage in membrane technology. The instructors led a full day of membrane work and technical theory discussion mixed with stories of past challenges faced by RO plants around the world. The morning session was filled with extensive discussion of membrane operation and troubleshooting from a membrane and equipment perspective which was presented by Mr. Jason Deal of CSM. The afternoon session wrapped up the membrane operations and troubleshooting from a chemical and process perspective which was presented by Mr. Coley Ali of BWA Water Additives. In relating to each of the members in attendance, both presenters shared stories of experiences to demonstrate the techniques and practices discussed at the event. Closing out the

event, Mr. Pierre Vignier and Dan Burdett of Port St. Lucie lead the entire group on a tour of the Prineville RO plant highlighting many of the improvements in process as well as energy efficiency completed over the last few years. On behalf of SEDA, we would

like to extend a special thank you to Pierre, Dan and the City of Port St. Lucie for hosting a great event. In addition, SEDA would like to thank both presenters for sharing their knowledge and their donation of time to present this material. Lastly, SEDA would like to thank our sponsors Hydranautics and CSM for supporting the event and our membership through their financial contribution. For those operators looking for CEUs or just want to learn

more technical membrane knowledge and skills, several Technical Transfers are being presented this fall and early next year. Be sure to check the website (www.southeastdesalting.com) for events and topics of interest for you. We look forward to seeing you there!

Technical Transfer Workshops: Events that Save Your License

Sixteen SEDA members from around Florida attended “Chemical Pretreatment For RO” hosted by the City of Dunedin on September 18th. American Water Chemicals (AWC) sponsored the Technology Transfer Workshop and AWC’s CEO/Technical Director Mo Malki led the group through an in-depth presentation on the various types of chemical pretreatments available for RO systems and their applications. John Van Amburg, Water Production Foreman for the City of Dunedin led the group on a tour of the facility and discussed the history of the City’s water system and the plant, as well as the current status of the City’s utility system.

Dunedin hosted a SEDA Technology Transfer Workshop in September

Operators all across the southeast are due up for license renewals in the coming year. Don’t let your license renewal lapse because you can’t find CEU Credits. Register for the upcoming Technical Transfers as we close out the 2012 calendar year and open the 2013 with a bevy of choices. Starting off the month of December, events will be hosted in Collier County and Palm Bay, Florida on December 4th and 6th, respectively. An additional event will be hosted in Mt. Pleasant, South Carolina on December 5th. These and other Technology Transfer events can help you save your license so please, mark your calendars for these events and get those CEUs early.

For those of you looking to get the New Year started off with CEUs, we are kicking off the 2013 schedule with two Technical Transfers in January. The topics covered will be Chemical Pretreatment for RO in Lakeland, Florida and Pretreatment for RO/NF in Jupiter, Florida. One event is scheduled for February to highlight Chemicals, Optimization, Metering and Monitoring in Clearwater, Florida. We are also planning on hosting two Technical Transfer events in March to fulfill those last minute CEUs prior to renewal. Stay tuned to the SEDA website for more updates and new Technical Transfer event postings. Thanks to the new website upgrade, you can actively view the upcoming brochures and register online for SEDA events. Visit www.southeastdesalting.com/

calendar/ to register for these and other events.Those who attended the last two Technical Transfers can attest,

seating has been booked quite quickly. As many of you attended the Chemical Pretreatment for RO event held in Dunedin on September 18th or the Operating and Troubleshooting Membrane Systems event in Port St. Lucie on October 17th which reach capacity several weeks prior to the event. If you are planning on attending a Technical Transfer event, be sure to register early as many locations offer limited seating only and late registrants will be turned away. Finally, we ask that you provide feedback and input at all of our events to help focus our efforts on serving your needs as operations and utility staff. Please send any preferences for desired training topics that would be beneficial to you or your facility as we would like to expand our events and bring those topics to a facility near you.

SEDA Awards It’s a BIG Year for Electionsby Sean McFarland David M. Laliberte, SEDA Elections Committee Chairman

SEDA members, it is that time of year again to show off your plant to your fellow professionals or nominate one of your fellow employee’s as the SEDA Outstanding Operator Award. The 2012/2013 plant award is being broke-down into two categories. There will be a 5 MGD and smaller award as well as a 5 MGD and larger Membrane Plant award. The form for the Membrane Plant award has also been shortened to make it easier for a utility to fill out. The cash prize amount for the plant and the operator award is $100.00 for each. The forms can be found on the SEDA home website (www.southeastdesalting.com) on the Awards link in a Word or PDF file. The deadline for submission is February 8, 2013. We plan to visit the plants that qualify for the final award after reviewing the submissions and will speak personally with the operators who make the final cut.

We are moving into the election season, not only for the US President but also for the 2013-2015 SEDA Board of Directors. Becoming a nominee for the Board of Directors does not require a large advertising campaign, debates or television commercials across the country. It does, however, require contributing hours of service to the organization in the areas of environmental regulation and legislation, teaching and training, operation and maintenance, process design, equipment education, research, and hands on training. The SEDA Board of Directors is always looking for people who would be willing to contribute their experience and knowledge to the SEDA organization.

We are accepting nominees for the upcoming 2013-2015 Board. If you have an interest in supporting SEDA by participating as a Board member or assisting as a committee member, please contact the SEDA Election Committee at 772-781-7698.

One of the primary goals of municipal water purveyors is to protect the health of its consumers. Disinfection provides reasonable assurance against exposure to harmful bacteria and viruses, however, disinfectants themselves can react with naturally occurring materials in the water to form byproducts, which may pose additional health risks. As such, the Environmental Protection Agency (EPA) continues to develop rules that balance the risks between exposure to pathogens and disinfection byproducts (DBPs). In 2006, the EPA initiated the Stage 2 Disinfectant and Disinfection Byproducts Rule (Stage 2 DBP Rule). The Stage 2 DBP Rule builds upon the existing Stage 1 DBP Rule to provide increased protection against exposure to DBPs. DBPs regulated under the Stage 2 Rule include total trihalomethanes (TTHM) and five haloacetic acids (HAA5).

As a review, some of the critical requirements under the Stage 1 DBPR included maintaining TTHM and HAA5 concentrations below their associated maximum contaminant levels (MCLs) of 0.080 and 0.060 mg/L, respectively. For larger systems, four locations were sampled four times per year (quarterly). Municipalities selected three sampling locations with average distribution system residence times and one remote location. System wide running annual averages (RAAs) for TTHMs and HAA5s were determined from the four sampling locations, and had to remain below their associated MCLs. For smaller systems, compliance was based on monitoring once per year, when the levels were expected to be the highest, and at one location, again where levels were expected to be highest.

The Stage 2 DBP Rule introduced several changes;

however, the MCLs for TTHM and HAA5 remained the same. The first requirement under the Stage 2 Rule was for utilities to conduct an Initial Distribution System Evaluation (IDSE) to identify locations with the highest DBP concentrations. Systems receiving a 40/30 certification (previously demonstrated that Stage 1 DBP Rule compliance samples were less than or equal to 0.040 mg/L for TTHM and 0.030 mg/L for HAA5) or systems that served fewer than 500 people while having eligible TTHM and HAA5 data were exempt from conducting an IDSE, however were still required to comply with the Stage 2 DBP Rule. The locations identified in the IDSE with the highest TTHM and HAA concentrations are intended to become the new sampling sites for Stage 2 DBP Rule compliance monitoring.

Under the Stage 2 DBP Rule, the requirements for the number of new sampling locations range from two for smaller systems up to eight for larger systems. Again, it is required that new sampling locations represent the “worst case” or highest DBP concentrations in the system. Another change reflected in the Stage 2 Rule reuiqres systems to meet TTHM and HAA5 MCLs as an average at each new compliance monitoring location, also known as determining the locational running annual average (LRAA) rather than the RAA specified in the Stage 1 DBP Rule. The following example demonstrates the potential significance of this rule change.

ExampleThe DBP monitoring results for a system that samples at

four locations, four times per year is shown in the following table. The values represent TTHM concentrations expressed as mg/L.

ResultsA. Stage 1 DBP Rule compliance monitoring required that the

system-wide RAA of the TTHM concentrations remain below the 0.080 mg/L MCL.• The system-wide RAA = 0.063 mg/LSince the TTHM RAA is less than the 0.080 mg/L, the system

remains in compliance with the TTHM requirements of the Stage 1 DBP Rule

B. Stage 2 DBP compliance monitoring requires that the site specific LRAA of the TTHM concentrations remain below the 0.080 mg/L MCL

• LRAA for Location 1 = (0.051 + 0.042 + 0.061 + 0.045)/4 = 0.050 mg/L

• LRAA for Location 2 = (0.071 + 0.057 + 0.065 + 0.068)/4 = 0.065 mg/L

• LRAA for Location 3 = (0.069 + 0.054 + 0.043 + 0.061)/4 = 0.057 mg/L

• LRAA for Location 4 = (0.075 + 0.083 + 0.084 + 0.085)/4 = 0.082 mg/L

Page 7: FALL 2012 SEDA/AMTA Key Largo Workshop

RECOVERY ZONE 7

Since the TTHM LRAA of one of the locations, Location 4, is greater than 0.080 mg/L, the system has violated the Stage 2 DBP Rule.

The final change introduced in the Stage 2 DBP Rule is the requirement for systems to conduct operational evaluations initiated by the operational evaluation levels (OEL) found in Stage 2 compliance monitoring. OELs are set at the same level as the MCLs for TTHMs and HAA5s (0.080 and 0.060 mg/L).

They are calculated as follows:

OEL = [(2*A) + B + C]/4

Where:

A = TTHM or HAA5 results for the current quarter;

B = TTHM or HAA5 results for the previous quarter;

C = TTHM or HAA5 results for the quarter before the previous quarter

This new requirement has been initiated as a way to provide an early warning of possible future MCL violations, which allows a system to take proactive steps to remain in compliance. A system that exceeds an operational evaluation level is required to review their operational practices and submit a report to their state that identifies actions that may be taken to reduce future high DBP levels. This could include examining the following:

• Storage tank operations

• Excess storage capacity

• Distribution system flushing

• Changes in sources or source water quality

• Treatment changes

If a system determines that their OELs do not exceed 0.080 mg/L for TTHM and 0.060 mg/L for HAA5, then an operational evaluation and report are not required.

The compliance activities introduced by the Stage 2 DBP Rule are outlined in the following table along with associated start dates according to system size.

Ben’s Tip CornerConfirm That Your Automated Valves Are Working Correctly

When a new system is commissioned it is reasonably safe to assume that all the automated valves will be calibrated and checked during the commissioning of the system.

Physically check that valves are functioning correctly on a regular basis

The larger and more complex systems have many automated valves. Over time sometimes one or more of these valves may not be in the position that is indicated on the HMI. Depending on which valve and its function in your system this could cause some very serious problems. I would offer the following scenario to make my point.

Visualize a large multi train system that operates from a common feed header. The system is large enough that it has significant excess capacity. The system operational program is set to close all valves on any train that is not in use. The trains are rotated daily to keep all trains sweet and free from biologic activity.

Over several months a steady decline in permeate quality is noticed on one train. After a cleaning and other investigation this train continued to be in a state of decline. Finally a very detailed investigation was done and the culprit turned out to be the Train Feed Valve.

Although it was indicating closed on the HMI it was actually stopping a few degrees short of fully closed. Anytime this train was off line it was actually producing some permeate at 100 percent recovery. Over several months this was the cause of the quality decline. Once the valve was recalibrated the problem was resolved.

You must remember that these valve actuators have several cams and micro switches that can ware or move slightly over time. Be sure that what you think you are seeing is what you are actually getting.
