One Utilities Experiences on Permitting for Desalter Brine and Concentrate Recovery to Minimize Disposal of Reusable Resource
This paper and presentation will provide the steps and methods used by the Irvine Ranch Water District (IRWD) on the permitting and concentrate recovery methods for the Irvine Desalter Project (IDP) and the Deep Aquifer Treatment System (DATS)....
IRWD's Experience with MBR
This presentation provides an overview of MBR technology and presents a case study for procurement of MBR. Advantages of MBR including higher MLSS concentrations; effluent quality not dependent on operations; smaller footprint, modular units and other parameters that result in a higher quality effluent are Included in the presentation....
Case Study for Irvine Ranch Water District - Fouling of NF Membranes
This paper is a case study of the Irvine Ranch Water District (IRWD) in Orange County, California that provides potable water (local groundwater and imported), wastewater treatment for the production of recycled water, and natural treatment system to clean urban runoff. IRWD has several membrane treatment facilities that include the Deep Aquifer T...
Integrated Membrane Portfolio Key Role for Water Supply For Water District in Arid Southwest
The IRWD was a typical water agency in southern California, utilizing imported surface water supplies for potable water usage. As demands for water increased the District evaluated multiple, local water sources, resulting in the development, construction, and operation of five membrane technologies: DATS NF, CATS NF Plant, DP-PTP RO Plant, Desalter...
Qualification Membrane Demonstration Study Concentrate Recovery System
Demonstration study results of an alternative membrane for application at a concrete recovery membrane system will be provided including train modifications, test protocol, operating procedures, process control monitoring, data gathering, results, and recommendations. Experience gained from testing an alternative membrane will be shared with fellow...
DATS/IDP Instrumentation Modifications to Enhance System Performance Monitoring
Membrane plants using spiral wound membranes typically are constructed with instrumentation for monitoring the performance across the entire train, however, membrane plants are typically comprised of multi-staged trains, and to properly perform the process control and monitoring of each stage, many existing plants must be retrofitted. The case stud...
Repair and Rehabilitation of Twenty-Year-Old NF Plant Trial and Tribulation
The Deep Aquifer Treatment System (DATS) is an 8-mgd nanofiltration (NF) plant owned and operated by the Irvine Ranch Water District (IRWD) located in Santa Ana, California, that was put online in February 2002 and has successfully operated in the removal of natural organic color causing compounds utilizing organic selective membranes. The facility...
