WATER MEMBRANES RESOURCES

• Optimal Ultrafiltration Uses For Beverage And Dairy Companies

  When you’re sipping on a cold soda or snacking on a creamy piece of cheese, you probably don’t really think about what went into making your food or beverage. Aside from the automated production-line machines, one of the most important things that goes into the making of any soda, juice, wheel of cheese, or gallon of milk is water. Producing beverages and dairy products uses substantial amounts of water within production processes.

• Mobile Home Park Installs Modular MBR System To Save Valuable Space

  Bay Meadows is a year-round RV and mobile home park located along the shores of Lake Ontario. The facility had been reliant on subsurface treatment, however current regulatory requirements eliminated the option of continuing with that approach. In addition to high bedrock, the lack of available area due to design flow values meant a more sophisticated sewage treatment solution would be necessary.

• Low-Fouling RO Tech Keeps Replacement Costs Down At Wastewater Reuse Plants

  By using Toray's low-fouling polyamide composite membranes, the WTPs at the AMATA estates operated the RO systems for more than five years before requiring replacement of the RO elements. This low rate of replacement has considerably helped the end-user save operational and capital costs and is noted as one of the most successful wastewater reuse plants in Thailand.

• Cost-Effective Sludge Thickening Processor Using MEMBRAY™ Membrane Bioreactor

  The Valley Center Municipal Water District (VCMWD) operates two wastewater treatment facilities in Valley Center, which is located in the northern part of San Diego County, California. Both WRF's incorporated an in-house membrane thickener (MBT) design and selected Toray's MEMBRAY™ Membrane Bioreactor (MBR) modules for the process. VCMWD's objectives were to conserve water and meet the Regional Water Quality Control Board's effluent standards (Title 22), so the reclaimed water can be used for irrigation and other reuse applications. The MEMBRAY™ MBR modules helped the local utility achieve these goals.

• Butler WTP Solves Membrane Integrity Issues And Meets EPA LT2 Rule With Aqua MultiBore® Membranes

  Butler Water Treatment Plant (WTP), located in Missouri, receives its influent from a surface water impoundment fed from Butler Lake, Maris de Cygenes River, and Miami Creek. Following treatment, it provides potable water to over 300 businesses, (4) schools, 4100 residents and (4) other Public Water Supply districts.

• PVDF Hollow-Fiber Ultrafiltration Membranes Selected For Plant Upgrade

  The City of Delaware, Ohio's Water Treatment Plant (WTP) started operating in 1889. Under the EPA's Long Term 2 Enhanced Surface Water Treatment Rule (LT2), the WTP's feed water is classified as Bin 2, which requires a 4-log removal of Cryptosporidium. As a result, the City would convert its 6.0 MGD lime softening plant to a 7.2 MGD membrane treatment facility utilizing a 4.5 MGD ultrafiltration (UF) system to comply. A total of seven proposals were received during the bidding phase of the UF system, which was narrowed down to three based on best projected capital and operating costs and membrane performance. The three selections would be piloted for further evaluation. Read the full case study to learn more.

• When To Replace Your RO Membrane

  On the surface, it might seem that knowing when to replace the membrane elements in a reverse osmosis (RO) system would be simple. In attempting to keep it simple, many companies will use one or more of the following guidelines for replacing their membrane.

• High-Flux Membrane Filtration For Oil And Water Separation

  Environmental regulations and water scarcity have created a need for economical water treatments that increase reuse. This paper will review the new PPG membrane that has a unique composite single-layer microstructure that provides high-flux, excellent separation capabilities and exceptional durability to improve the filtration and recovery of industrial wastewater.

• High-Flux Polymeric Membrane For Industrial Water Separation

  Water is essential to numerous industries such as chemical manufacturing, automotive production, oil and gas refinery and power generation, yet the increasing scarcity of this precious resource makes its recovery from these activities more critical than ever.
