Overview of Membranes & Terms MF, UF, RO, NF and MBR
The presentation will give a brief introduction to membrane technology including microfiltration, ultrafiltration, nanofiltration, reverse osmosis and membrane bioreactors. Terminology and operating parameters will be discussed as well as differences between the different membrane processes....
A Novel Approach to the Management of RO Concentrate Derived from Coal Seam Gas Water Treatment
The extraction of coal seam gas (CSG) produces significant quantities of brackish water. After separation, the brackish water is typically treated by RO plants to enable beneficial use of up to 90% of the water, with the remaining RO concentrate (or brine) stored until its final management is determined. Reducing brine volume through further treatm...
Advanced Purified WTP Water Quality Sampling and Monitoring for Direct Potable Reuse
This presentation is intended to inform a utility engineering and operations audience a general understanding of how the El Paso Utilities has approached the idea of implementing direct potable reuse to the City. The proposed Advanced Purification Water Treatment Plant (APWTP) is designed to provide the City with additional potable water to meet t...
Implementing CCDTM Reverse Osmosis to Minimize Water Footprint
This presentation provides a general overview of the water issues surrounding the southwestern United States and sustainable measures that can be implemented to reuse valuable wastewater resources for agriculture and indirect potable reuse applications. As the growing population of the southwest moves inland, the need for maximizing water resources...
Scottsdale Water Campus Overview & Tour
An overview and tour of the City of Scottsdale's 20 mgd advance water treatment plant (AWT). Scottsdale's AWT takes tertiary treated effluent, processes it through an ultrafiltration and reverse osmosis process for delivery to 22 golf course for irrigation needs and or distribution into 63 vadoze zone injection wells for groundwater recharge of a p...
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...
Inland Concentrate Methods in the Southwest
Reverse osmosis (RO) is a proven technology for the removal of high concentrations of total dissolved solids. One of the major challenges of any RO system is the disposal of the brine, or concentrate, which is produced during normal operations. The treatment of brine is typically undertaken to minimize the cost of disposal or to maximize the reco...
Wetland Treatment of Reverse Osmosis Concentrate
The City of Goodyear and the U.S. Bureau of Reclamation partnered to study wetlands treatment of reverse osmosis (RO) reject concentrate. RO concentrate includes elevated concentrations of contaminants that are removed during treatment of brackish water for potable water use. Contaminants include salts, metals, and nutrients typically at concent...
Are Operations Ready for Direct Potable Reuse?
With the increasing frequency and severity of drought, agencies across the United States and in particular in Texas have been turning to the potable reuse of municipal wastewater, either directly or indirectly, to help meet growing demands. It is important for any water treatment facility to have a high level of reliability to ensure water quality...
Squeezing Every Last Drop
Constructed in 1995, West Basin's Edward C. Little Water Recycling Facility (ECLWRF) treats municipal secondary effluent from the City of Los Angeles' Hyperion Wastewater Treatment Plant for a variety of reuse applications. West Basin has expanded the ECLWRF four times since startup, and has also added three satellites treatment facilities, which a...
Membrane Systems For Sustainable Solutions
Sustainability or the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs is an important consideration for any project. The need to achieve a sustainable design means that we need to evaluate the circumstances where resource recovery makes the most sense. Membrane systems such as ...
Operating RO Plants in Remote Locations
Osmoflo remotely operates more than 120 plants that are located across Australia, Hong Kong, New Caledonia and Chile. More than 50% of these are located in remote locations, having significant distances from a major city and remotely operating the RO plants is a challenge. To overcome the challenges innovation has been applied in man, machine, meth...
Chemistry of Difficult to TreatWaters
Membrane system design is a dynamic process. Systems that were designed 20, 15, even 10 years ago are often quaint by today's standards. Membrane manufacturers have developed new technologies that allow for higher recovery. Water plants have become more conscious over the years of trying to eek out every drop of water possible. And the industry has...
11 Years of Successful Brackish Water RO Membrane Operation with High silica in well water
Case study of a brackish water Reverse Osmosis plant in Virginia which has been in operation on original membranes for eleven years will be presented. The raw water from wells has a high silica content. Various blending scenarios were investigated during study phase. The plant final design was based on optimum bypass blend, which has been proven to...
