This paper will outline initial public outreach efforts in Corpus Christi Texas, lessons learned, public concerns associated with locating desalination facilities on North Padre Island, a barrier island, and a proactive public involvement plan for carrying out project implementation...

This presentaiton will provide an overview of the types of fouling that affect spiral wound membranes. Details of fouling and scaling are investigated as well as how to develop appropriate cleaning criteria. Chemicals used to clean membranes and safety considerations are coverd as well....

This presentation provides details about Twin Oak Valley water treatment plant located in Northern San Diego County. This is a 100-mgd drinking water treatment plant with GE Submerged Membranes. AN overview of the permitting, construction, operations and cleaning chemicals and energy costs is provided....

This PowerPoint presentation describes the membrane treatment plants in Hawaii and the Regulatory concerns...

All raw waters contain microorganisms such as bacteria, fungi, virus, algae, which have the ability to reproduce and form a biofilm under favorable conditions, like on the surface of a reverse osmosis (RO) or nanofiltration (NF) membrane, where nutrients dissolved in the water accumulate. Like all the depositions on membrane surfaces, biofouling ma...

Irreversible membrane scaling caused by silica remains a severe problem in many reverse osmo-sis plants. The engineering task is to find out the appropriate anti-scalant agent and its optimal dosage. Because suitable test methods are missing, a new membrane-based test method was de-veloped. The fully automatically controlled test set-up and the tes...

Paper presents the deisng considerations of the Jurong membrane bioreactor treatment facility in Singapore. The plant was designed retrofitting existing aeration basins with a membrane bioreactor to produce effluent which is suitable for reuse in industrial applications. Report outlines steps taken that are expected to reduce overall energy consump...

This paper describes an in-depth investigation of a steel companies waste water by looking at the feed water quality including size fractionation and chemical analyses of feed water constituents, bench scale fouling and scaling studies while applying some proprietary geochemical and RO process modeling tools. From these analyses, they were able ...

The oxygen transfer efficiency in the aeration process plays a large role in determining the size and footprint of MBR equipment. Higher concentrations of MLSS tend to restrict the oxygen transfer process when using a conventional fine or coarse bubble process. The Supersaturated Dissolved Oxygen Injection System (SDOX) significantly increases oxyg...

Presents how RO technology is applied in different types of feedwaters by modifying the arrangement of commercially available membranes within the RO system....

Research a new FO draw solution of EDTA-2Na combined with a nonionic surfactant (Triton X-100) to reach zero salt reverse sault diffusion. Assess the efficiency of FO performance with various EDTA-2Na concentrations and various Triton X-100 concentrations. Recovery of diluted draw solution using nanofiltration (NF)....

The paper discusses the first full-scale vendor supplied Anaerobic Membrane Bioreactor AnMBR) system in North American at Ken?s Foods plant Foods in Marlborough, Massachusetts that has been treating salad dressing and BBQ sauce wastewater successfully for seven years since being commissioned in July 2008. The (AnMBR) process incorporates anaerobi...

The presentation will discuss the applicability of Silicon Carbide ceramic submerged UF membranes for industrial applications, including the advantages and limitations. In addition to this, a comparison to conventional organic membrane technologies is included along with case study data and field experiences....

Prestage Foods is building the most modern and technologically advanced pork processing plant in North Central Iowa. Construction began in the Spring of 2017 with the project opening to be in late 2018. With a facility of this size, water quantity and quality was a main concern. Requirements for the water quality could only be met through membrane ...

This presentation will address the use of a proprietary direct organic solvent extraction technology for the desalination of high salinity oil and gas produced water. The topics include an overview of the market application, a description of the treatment technology, cost figures, and current state of development....

Water efficiency (recovery) for industrial process and wastewater treatment is often limited by hardness and silica levels in the feed stream. In particular, water efficiencies above 90% often lead to significant operational challenges for membrane desalination systems. This presentation will discuss the challenges presented by hardness and silic...
