WATER MEMBRANES RESOURCES

• Technologies That Can Achieve Water And Sanitation For All

  A staggering four billion people — two-thirds of the world’s population — experience water scarcity each year, and more than half lack access to safe sanitation services. The severity of this global water crisis will only increase as populations continue to rapidly grow, industries exhaust shared resources and extreme weather events exacerbate shortages. If we don’t act urgently, 700 million people could be displaced by intense water scarcity in just a few short years.

• Liqui-Flux Case Study: Large-Scale Treatment Of River Water For Industrial Use

  Ultrafiltration (UF) is commonly used as a pre-treatment to Reverse Osmosis (RO) to ensure reliable, consistent and efficient operation. As Shandong Hongxin Chemicals Co., Ltd in China recently discovered, this consistency and reliability, along with quick setup and installation times, helped them realize convenience and cost savings.

• UF/RO System Treating Mine-Influenced Water To Remove Selenium

  A Phosphorus mine in Wyoming needed to treat high selenium concentrations leaching into the surface water. A 3-month pilot study of a UF/RO system was conducted to reduce selenium levels under the US EPA's maximum contaminant level (MCL) of 0.05 mg/L, and mitigate impact to the ecosystem, especially aquatic species. Read the full case study to learn how Toray's high-rejection energy-efficient RO (TMGD series) removed the selenium at reduced feed pressures, projected to save the plant energy costs for years.

• Retrofit Expansion Of An Ultrafiltration System Using TORAYFIL™ UF Modules

  The Brazos Regional Public Utility Agency (BRPUA) in Texas operates the Surface Water and Treatment System (SWATS) that treats water from Lake Granbury, fed by the Brazos River. The SWATS facility first began operating in 1988 with clarification, dual media filtration, and electrodialysis reversal (EDR). The plant was upgraded in 2001 to include ultrafiltration (UF) and reverse osmosis (RO) membrane treatment to produce higher quality effluent.

• 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.
