Before 2005, there were no industry-wide concentrate management performance standards for the types of desalination technologies identified in "Desalination and Water Purification Technology Roadmap" (joint authors were Sandia National Labs and the Bureau of Reclamation). Additionally, brackish and sea-water desalination and concentrate management regulations varied significantly from state-to-state, region-to-region, and internationally, in terms of both field testing and monitoring requirements. For example, the best management practices recommended for concentrate disposal in one state may not be allowed in an adjoining state. In other cases, receiving water quality criteria either do not exist, or may require a concentrate stream's quality to be significantly better than the quality of the receiving water. In 2005, several organizations including the American Water Works Association, Ground Water Protection Council, Water Reuse Foundation, and the Environmental Protection Agency agreed to work cooperatively through an American Society of Civil Engineers (ASCE)-Environmental and Water Resources Institute's (EWRI) task committee to develop a consensus-based assessment and provide recommendations and guidance on sound and commonly acceptable concentrate management practices for new and existing desalination and water reuse facilities of all sizes. Since that overall effort was not funded by outside sources of ASCE; the EWRI task committee (TC) has strived to be converted to a technical committee under the Water, Wastewater, and Stormwater Council of EWRI of ASCE. The TC began working to establish appropriate writings about case studies on concentrate management projects and other activities in desalination during 2006-2008. A two session track was held in Tampa in May 2007 along with a TC of CM in Desalination meeting that established outline material for future documents. Another EWRI Congress session was held in Honolulu in May 2008 and in Kansas City in May 2009. At the beginning of FY09, the new Concentrate Management in Desalination (CM in Desal) technical committee volunteered to develop a EWRI Monograph on case studies prepared in its ASCE eRoom by individual members of its four practice area subcommittees and using presentations at the 2007-2009 EWRI Congress tracks. This paper provides an overview of the goals, objectives, schedule, and progress to date of this overall long-term effort. The task committee's officers for FY 2010 will use the task committee proposal and some accomplishments to date of these activities for the basis of this paper at the 2010 EWRI Congress in Providence, RI. © 2010 ASCE.

Leading up to the current drought, EPWU had already diversified its water supply portfolio through use of brackish groundwater via the Kay Bailey Hutchison Desalination Plant, IPR through groundwater recharge at the Fred Hervey Water Reclamation Facility, and strong conservation measures. The proposed AWPF will further diversify EPWU's water resource portfolio with a locally controlled and reliable supply via DPR. The feasibility of implementing DPR in Texas has been demonstrated through CRMWD's raw water production facility and Wichita Falls' Cypress Hill WTP. However, EPWU's AWPF concept is unique in providing full advanced treatment to produce purified water for introduction directly to the distribution system. Drivers for this particular potable reuse concept for EPWU include the proximity of the Bustamante WWTP to the distribution system served by Jonathan Rogers WTP, absence of a yearround surface water supply to facilitate blending, and the reality of technological capabilities to reliably produce purified water that meets and exceeds all drinking water standards. The planned AWPF treatment process train includes multiple barriers for pathogens and diverse treatment for chemical microconstituents, including consideration of a range of NF and RO membranes as alternatives for the desalination process. NF treatment may be an option for membrane desalination, providing potential benefits of lower energy requirements and costs; permeate water quality more consistent with current water quality in EPWU's distribution system; and a concentrate stream with lower TDS, sodium, and chloride concentrations. Initial planning for the AWPF included concept development, regulatory coordination, IAP review, and public outreach. TCEQ approved the pilot testing plan for the AWPF concept in April 2015, and pilot testing is ongoing. Not only will this pioneering project provide a sustainable source of water supply for El Paso, it is also expected to help pave the way for similar DPR efforts around the country. © 2015 American Physical Society.

Severe restrictions exist in the disposal of the concentrate from the 15 mgd (2370 m3/h) reverse osmosis (RO) plant in El Paso, Texas (i.e., 15 mgd blended to 27.5 mgd). The current permit for the disposal by deep well injection limits the total dissolved solids in the brine to 10,000 mg/l. This limits water recovery in the plant and drives up the cost of sending a large volume of the concentrate a long distance for discharge. We have continued to work on developing a concentrate treatment process aimed at zero liquid discharge or a greatly reduced concentrate volume suitable for evaporation ponds. This is an interim report documenting an exciting demonstration of the feasibility of using a seawater RO system and synergistic antiscalant and low pH inhibition of reactive silica polymerization to concentrate the primary brackish water RO concentrate to total silica concentrations exceeding 1000 mg/l. This approach makes possible the use of tandem brackish RO followed immediately by a seawater RO (SWRO) to achieve an overall water recovery of greater than 96%, limited only by the highest pump pressures to overcome the resulting osmotic pressures. Pilot plant data using a single SWRO membrane and 700-740 psi feed pressure concentrating the brackish RO concentrate in a batch recirculation mode is presented. Recoveries of water in the 84-96% range were performed repeatedly with no apparent fouling of the membrane and no precipitation in the super-concentrate. The flux reduction curves in each case are consistent with gradual reduction of net driving pump pressure due to the rise in osmotic pressure that needs to be overcome. The reactive and total silica concentration profiles provide insight on the effects on membrane operation during buildup of reactive silica concentration with or without the increasing amounts of colloidal polymeric hydrated silica expected from the spontaneous polymerization of the reactive silicic acid monomer. © 2010 Desalination Publications.

El Paso Electric Company (EPEC) is the sole commercial electricity provider for two metropolitan economies in the southwestern desert region of the United States: El Paso, Texas and Las Cruces, New Mexico. A publicly traded corporation, EPEC employs a structural econometric system of equations model to forecast energy sales for various customer classes. Although the modeling system has provided reliable inputs to annual corporate planning efforts at EPEC, its historical track record has not previously been formally assessed for forecast accuracy. Both descriptive and inferential statistics are used to evaluate the EPEC model’s forecasting performance. Results indicate that accurate prediction of electricity usage in this service area is an elusive target. Those results are similar to what has been documented for other regional economic variables. © 2015, Econjournals. All right resurved.

Arsenic (As) is present in several of the wells that El Paso Water Utilities (EPWU) uses as part of the drinking water supply. EPWU has several wells that are equipped with reverse osmosis (RO) systems for desalting brackish groundwater. This process is referred to as Wellhead RO. At most of the wells, the RO membranes do an excellent job of rejecting As, but at one of the well sites, As rejection is less than 40%. Several techniques were investigated for removing the As, including new standard RO membranes, high-rejection (HR) RO membranes, and oxidation of As followed by standard membrane treatment. This paper presents the results obtained from pilot testing the standard and HR membranes, pilot testing of arsenic oxidation by chlorine and hydrogen peroxide, and full-scale implementation of a prechlorination/dechlorination process for arsenic oxidation prior to treatment in a reverse osmosis treatment system. The results showed that new standard RO membranes rejected 95% of the TDS and 58% of the As, while the high-rejection membranes rejected 98% of the TDS and 77% of the arsenic. Where blending with feed water is practiced, it appears that the relatively small extra cost of the HR membranes compared to the standard membranes would be economically justified. The capital and operating costs for retrofitting a well with a chlorination/dechlorination system are very economically attractive at 34∫ per 1000 gallons in the example cited here. © 2012 American Water Works Association.

A major obstacle to large-scale water desalination (desalting) projects in inland areas of the United States is disposal of the concentrated brine that is generated in a reverse osmosis or nanofiltration process. This problem is exacerbated when the concentrate contains a significant amount of silica, a common occurrence in groundwater in the southwestern United States. This project was undertaken to investigate using a batch-treatment seawater reverse osmosis (SWRO) system to reduce the volume of silica-saturated, reverse osmosis (RO) concentrate by recovering most of the water from the concentrate. The pilot-scale treatment plant that was used in this project was a four gallon per minute (15.1 L/min), fully-automated, data logging batch-treatment seawater reverse osmosis (SWRO) system. The RO concentrate that served as the feedwater supply for the SWRO unit was generated at the Kay Bailey Hutchison (KBH) Desalination (Desalting) Plant. The KBH Plant is located in El Paso, Texas. Test results showed that by reducing the pH to less than 4.5, and using an antiscalant for calcium sulfate control (an antiscalant for silica control was already present in the concentrate), recoveries in the 85-90% range were achievable with the SWRO system without fouling the membranes. Reactive silica concentrations of over 1000 mg/L were measured in the concentrated concentrate. Implementation of a full-scale SWRO system at the KBH plant would generate an additional four million gallons of potable water per day at a cost of less than $1.87 per thousand gallons ($0.49/m3). Furthermore, at 85% recovery of concentrate, there would be a net cash flow exceeding $178,000 per year, and the overall water recovery at the plant would increase to 97%. © 2010 ASCE.
