State-of-the-Union of Inland Desalting: Western U.S. Case Studies
This presentation reviews how utilities evaluate alternative sources of supply to meet their potable water needs including desalination and membrane softening. General industry trends and project challenges specific to inland desalination applications in the western United States is reviewed....
Meeting Criteria for Water and Wastewater Systems Simultaneously Using Reverse Osmosis and Zero Liquid Discharge Technology
The California Department of Corrections and Rehabilitation (CDCR) has taken steps to improve the water supply system for the Deuel Vocational Institution (DVI) in Tracy, CA. In the past, the Institution supplied potable water to the facility from four slightly brackish groundwater wells. The groundwater has a TDS concentration of 1,150 to 2,200 mg...
Designing the World's Largest NF System for the Miami Dade Water and Sewer Department's 165-MGD GWUDI Upgrades Project
This paper discusses the designing of the 225 MGD Hialeah and Preston Nanofiltration Plant and the methodology and analyses performed to establish: membrane selection, design flux, system size and configuration and pumping strategy. Additionally, results from process validation testing are presented....
Checking In on the Chino Concentrate Reduction Facility
The Chino II Desalter (Chino II) began operation in 2006 to expand the capacity of the groundwater treatment system with a combined ion exchange (IX) and reverse osmosis (RO) treatment capacity of 10 million gallons per day (MGD). High salinity concentrate from the Chino II Desalter is disposed of through the Inland Empire Brine Line (IEBL). The IE...
RO/NF Membrane System Characteristics
This presentation covers main characteristics of RO/NF membrane systems. It provides an overview of NF/RO basic theories; system Components, typical process energy use, energy recovery system, operating parameters and performance monitoring. It also provides description of four main types of energy recovery devices used for these systems....
Pilot-Scale Evaluation of Three-Stage Nanofiltration for Treatment of a Hard, Highyl-Colored Groundwater
Paper presents the results of pilot testing of nanofiltration water treatment conducted on behalf of Miami Dade Water & Sewer Department. The pilot treatment train included dual media pressure filters, strainers, cartridge filters, three stage nanofiltration array and an ultraviolet system. The testing evaluated alternative membranes and optional o...
Improving Inland Water Use Efficiency in Municipal and Industrial Applications
Idaho Power's Langley Gulch power plant generates approximatly 300 MW of power per day using natural gas fired boilers. The facility uses water from lateral collection wells along the Snake River for both boiler makeup and cooling. The treatment systems had several single points of failure and areas of challenging operation. This paper discusses th...
