Bryce Danker (Hazen Sawyer) Speaks About Tertiary Membrane Bioreactors at the December LABS Meeting by Dan Gary At the December 14 LABS meeting, Bryce Danker (Hazen Sawyer) spoke about the design of a tertiary membrane bioreactor (TMBR) for pristine reclaimed water. Low turbidity water with a low concentration of ammonia (NH 3 ) and suspended solids was required by Tesoro Refinery for its cooling water. The West Basin Municipal Water District treats recycled water from the City of Los Angeles Hyperion Treat- ment Works at its Edward C. Little Water Recycling Facility in El Segundo, where it is tertiary filtered and disinfected to Title 22 recycled water standards, and further treats it by converting all the ammonia to nitrate (NO 3 - ) at its satellite Janita Millen- dar McDonald Carson (California) Region- al Water Recycling Plant. While the nitri- fied water is one type of recycled water made by the Carson water recycling plant, the facility also makes water treated by microfiltration (MF) followed by reverse osmosis (RO) for industrial boiler feed water. Mr. Danker and Hazen and Sawyer en- tered into this project when the design was 30% completed. The facility’s goal was to increase the productivity and reli- ability of nitrified product water in a compact footprint. Anticipated increased ammonia loadings would overload an original aging upflow biological aerated filter (BAF) that nitrified water. It was to be replaced with a robust, reliable and expandable method that could convert over 40 mg/L NH 3 to NO 3 - , reduce total suspended solids from 5mg/L to <0.2 mg/L, and produce <0.5 NTU turbidity waters (from water that entered the plant at 3 NTU turbidity). Although se- quencing batch reactors, moving bed bio- logical reactors and a new BAF were con- sidered, the TMBR was thought to be more favorable. A TMBR was pilot tested. Based on the pilot test, a TMBR composed of two aeration basins, a separate mem- brane chamber and a separate blower building was chosen (Figure 1). The mixed liquor will be circulated between the aer- ation basin and membrane chamber. Product water will be drawn off the top of the membrane chamber. Additional alka- linity is anticipated to be needed. To pro- vide the optimal amount of alkaline addi- tion, a control system will be provided that will set the alkaline solution flow rate based on current alkalinity and am- monium concentrations. The system will be built as an open membrane system, with tankage and support systems de- signed to suit multiple MBR vendors. Mul- tiple membrane systems within mem- brane basins will be present. In 2017, the design passed the 90% mark, with a membrane bioreactor vendor chosen. Construction of the TMBR will occur in 2018. Concluding the talk, Mr. Danker empha- sized that maintenance of plant opera- tions, flexibility (including designing for increased loadings), stakeholder input, and conscientious cost monitoring were all important in this project. The result of this project was an easy to operate, ro- bust tertiary membrane system that pro- duces low turbidity, low suspended solids, highly nitrified water to be used in cus- tomer cooling towers.

The Los Angeles Basin Section of CWEA Dinner Meeting and Presentation
Thursday February 22, 2018 U.S.C. Professor Amy Childress
Desalination of Water Using Membrane Distillation
Membrane distillation is a method of providing clean water from high salinity sources relying on a vacuum source to lower the pressure required for water to be distilled. Contaminants concentrate on outer side of a membrane tubes while condensate (distilled water) forms on the inside of the tubes. Dr. Childress will talk about membrane distillation and membrane fouling. When: Thursday February 22, 2018 Presenter: Dr. Amy Childress, Ph.D. 6:00 pm Social Hour U.S.C. Dept. Civil & Environ. Engineering 6:30 pm Dinner 7:00 pm Presentation 7:50 pm Questions Questions: [email protected] 8:00 pm End of Presentation Where: Taix French Restaurant Dinner Choices:

SIDE-STREAM & MAINSTREAM NUTRIENT workshop Cost Effective Strategies for Nutrient Removal
In 2015, WEF released The Nutrient Roadmap with an aspirational goal: The next generation of wastewater treatment has zero net impact with regard to energy use, greenhouse gas emissions and nutrient discharge by 2040. Achieving this goal requires a dedication to overcoming technical barriers, financial constraints, and regulatory disincentives limiting nutrient removal, greenhouse gas emission reduction, and energy neutrality in wastewater treatment. View the Nutrient Primer from WEF.
Solids handling recycle flows contribute substantial nutrient loads to the main plants. Therefore, better managing solids handling side streams, reducing the nutrient loads is one of the overarching goals of the POTWs for NPDES permit compliance. The focus of this workshop is on nutrient removal technologies currently in use and the next generation technologies in development. This interactive workshop will cover fundamental principles of short-cut nitrogen removal and how we can apply this knowledge to reliably and cost effectively treating ammonia thorough application of side stream and mainstream processes.

CALIFORNIA FOG workshop Seeing Through the FOG to Keep Pipes Clear
Fats, oil and grease were the #1 culprit of sanitary sewer overflows in the early 2000s.
We’ve increased compliance with inspections and cleaning programs. Sewer overflows
are now at an all time low. Yet, large, complex FOG challenges remain.
Speakers will revisit the regulations, discuss new, affordable grease removal
technologies, new compliance programs and discuss steps you should take to continue
improving your FOG program. Let’s bring an end to fatbergs, even the mini-bergs!
This unique workshop is jointly organized by CWEA’s Collection Systems and P3S
Committees to demonstrate we are stronger together in water when we work together.
This will be a fun day bringing together pretreatment inspectors, engineers and sewer
system professionals. Wednesday, February 14th
