LABS Members Win Big At 2009 CWEA Annual Conference By Alec Mackie Local members and agencies were big winners at the Annual Conference in Palm Springs earlier this year. LABS member and CWEA Past-President Dave Greenwood (LACSD) hosted the awards luncheon - handing out awards to dozens of agencies and individuals. Agency Awards The County Sanitation Districts of Los Angeles County (LACSD) won the Engineering Achievement Award for developing an innovative, cost-effective solution for the Antelope Valley that advances water reuse, protects local water resources, promotes sustainability, limits greenhouse gases and provides flexibility for growth, water reuse, and regulatory compliance. The projects will cost around $384 million, including: • Upgrading two LACSD Water Reclamation Plants (WRPs) including conventional activated sludge with nitrification/denitrification (N/DN), secondary flow equalization, tertiary filtration, and chloramine disinfection to produce Title 22 recycled water. • Storage reservoirs, pump stations, and pipelines to handle around 2.1 billion gallons of recycled water for agricultural and reuse needs. • Acquiring 9,700 acres for agriculture to provide reliability and flexibility while the customer base for recycled water develops. • Construction of 1 MGD pilot membrane bioreactor at the Lancaster WRP to optimize practices prior to large-scale implementation with upgraded WRPs. • Creating a partnership of nine Antelope Valley agencies to develop an Integrated Regional Water Management Plan for reuse and a "backbone" system to distribute the water. LA Wrecking Crew Wins Ops Challenge

After a tough loss last year, the LA Wrecking Crew’s grit and determination once again brought home the CWEA championship title and they advance to the WEFTEC national event. Stephen Johnson (LACSD) will serve as team coach at the competition in Orlando and feels they have an

excellent chance of bringing home the national title – the team took second last year. “The team had a better performance, a consistent performance (at CWEA) this year,” said Stephen. “I think we have the potential to do extremely well at WEFTEC.” The team has won WEFTEC six times and held the CWEA title for 15 years in a row until 2008. A new Ops Challenge event this year is the use of an Automated External Defibrillator to revive a heart attack victim in the Safety Event. Call for Abstracts

Leo J. Vander Lans Advanced Water Treatment Facility (AWTF) Tour By Wendy Wert On July 22, 2009 the Water Replenishment District of Southern California (WRD) hosted a tour of the Leo J. Vander Lans Advanced Water Treatment Facility (AWTF), which provides advanced treatment (microfiltration and reverse osmosis) to effluent from the Long Beach Water Reclamation Plant (WRP). The Long Beach WRP is owned and operated by the County Sanitation Districts of Los Angeles County (CSDLAC). Representatives from both agencies explained their unique partnership that is responsible for advancing responsible, local management of water resources by increasing opportunities for water reuse. Dave Snyder, of the Districts began the tour with a brief overview of the Long Beach WRP. The 25 million gallon per day (mgd) Long Beach Water Reclamation Plant began operation in 1973 and serves a population of approximately 250,000 people. Almost 5 mgd of the treated effluent is reused at over 40 sites, this includes landscape irrigation of schools golf courses, parks, and green belts and the re-pressurization of oil-bearing strata. The Long Beach WRP consists of primary (solids removal), secondary (biological activated sludge) and tertiary (filtration and disinfection) treatment stages. The secondary activated sludge process provides for nitrogen removal through the step feed process. This nitrification de-nitrification (NDN) process is similar to the conventional activated sludge process which provides for carbon oxidation only. The NDN activated sludge process requires a longer process optimization period to establish an adequate population of nitrifying organisms for ammonia oxidation. Due to their slow growth rate, nitrifying organisms typically require a longer mean cell residence time (MCRT) of 8 to 10 days depending on the wastewater temperature. The mixed liquor suspended solids (MLSS) concentration is in the range of 3,000 to 4,000 mg/L to accommodate the longer MCRT and to incorporate the available nitrogen into microbial mass as a result of cell growth. Conversion of ammonia and organic nitrogen to nitrate by the nitrifying microorganisms requires more process air than for carbon oxidation alone. In the step feed process one third of the aeration area is dedicated to the denitrification process, which occurs in an anoxic environment. In the anoxic compartment, the plant influent, return activated sludge, and nitrified recycle flow are combined and mixed by submerged mechanical mixers. This is where most of the nitrogen removal (denitrification) takes place.

Because denitrification is adversely affected by oxygen, contact with the air needs to be minimized in the anoxic compartments. The primary influent provides the carbon source required by denitrifying organisms in the anoxic environment to convert the nitrate in the recycle flow to nitrogen gas. While the daily influent flow rate remains fairly constant, biological NDN process is highly dependent on the return activated sludge and the nitrified recycle flow rate. Return activated sludge rate needs to be carefully determined to maintain the MLSS concentration in the reactor while ensuring adequate settling in the clarifiers. Nitrified recycle flow rate, which may range from 125% to 300% of the influent flow rate, is another important operational variable that affects the performance of the NDN process. Conversion of the Long Beach WRP to the step feed NDN process at the Long Beach WRP has eliminated the need for chemical addition upstream of primary treatment. Disinfection at the Long Beach WRP relies on a combination of free chlorine added prior to filtration and chloramination subsequent to filtration to minimize the formation of trihalomethanes. The City of Long Beach provided the Long Beach WRP property to the CSDLAC. As a term of this agreements the CSDLAC supplies the tertiary treated influent water to the Leo J. Vander Lans AWTF at no cost. Jim McDavid, of the WRD then explained that approximately 3.8 mgd of the Long Beach WRP effluent is sent to the Leo J. Vander Lans AWTF. This state-of-the-art treatment facility uses microfiltration, reverse osmosis and ultraviolet light to treat the water and insure that Southern California’s groundwater supply is sufficient, clean and safe. The purified water produced at the AWTF is almost like distilled water and is blended at a ratio of 50% recycled to 50% imported water and pumped into the Alamitos Seawater Barrier to protect the Central Basin groundwater from seawater intrusion.

The Leo J. Vander Lans AWTF provides advanced treated recycled water to the Alamitos Seawater Intrusion Barrier. The AWTF provides advanced treatment through a process train that includes microfiltration (MF), reverse-osmosis (RO), and ultraviolet (UV) light. Paul Fu of WRD explained that MF is a low-pressure membrane process that removes fineparticles, protozoa, and most bacteria out of the water. MF provides a very efficient pretreatment of water prior to the RO process. RO is a membrane process that forces water through the molecular structure of a thin-film membrane that filters out minerals and contaminants, including salts, viruses, pesticides and other materials. Paul explained that the primary purpose of the UV process is to reduce N-Nitrosodimethylamine (NDMA), which is a semi-volatile organic chemical that has a California notification level of 10 ng L−1 in drinking water.

The AWTF operations permit was approved by the Los Angeles Regional Water Quality Control Board on September 1, 2005, and the replenishment operations started in October 2005. The product water has since been discharging to the barrier to replace up to 50% of the potable imported water currently used, thereby improving the reliability and quality of the water supply to the barrier. The plant is designed to produce approximately 3,000 AFY for delivery to the barrier. Jim McDavid explained that testing has been completed to allow this ratio to be increased to 75% recycled water. Paul Fu stated that the injection operations for recycled water are restricted to ensure that there is at least a 6-month lag before recycled water reaches production wells. Advanced hydro-geologic model simulations are conducted to verify that operational pumping rates meet the requirement. For the imported water used for injection at the seawater barrier wells, WRD pays the premium price for “non-interruptible” water meaning that it will be available all year long. Because of the increasing water costs at the barriers, WRD is looking at ways to minimize costs such as reduction of pumping near the barriers, increased recycled water to offset imported water, or banking water at lower seasonal rates. The City of Long Beach and WRD have entered into an agreement to bank seasonal treated water through inland injection wells and then extract the water for injection at the barriers, thus saving considerable costs on barrier water. However, because MWD has halted the availability of seasonal water, the amount remaining in the bank has been put on hold. When seasonal water becomes available again, the storage bank will be refilled. The approximate cost of treated delivered recycled water from the AWTF is $800/AF, this includes capital costs ($450/AF), O&M costs ($600/AF) less the MWD local resource program rebate ($250/AF). The use of imported water to manage the ground water supply has been increasing in cost due to the State’s water crisis including drought, environmental concerns and energy concerns. WRD cannot buy imported water directly from MWD because it is not a member agency. WRD purchases water from the Central Basin Municipal Water District (CBMWD), West Basin Municipal Water District (WBMWD), and the City of Long Beach. The cost of replenishment water to WRD is the MWD rate plus any surcharges added by the member agencies. Recently, MWD made a substantial increase (approximately 30%) in their water rates due to drought conditions. As the cost of imported water increases and the availability of this commodity decreases, local solutions such as WRD’s Leo J. Vander Lans AWTF provide opportunities for sustainable regional groundwater management.
