DRINKING WATER FILTRATION RESOURCES

• Filter Membrane Predictive Maintenance

  At manufacturing operations using ultrafiltration systems, the ultrafiltration membranes are used for numerous batches without replacement, using Clean-In-Place (CIP) operations in between batches to maintain filter performance. However, ineffective CIP cycles or long-term fouling or degradation of the filter membrane can result in increased cycle times to move the desired amount of product through the filter, lost yield as the product is unable to permeate the filter, or poor product quality as membrane failure may occur.

• Drinking Water Treatment Plant (DWTP) Filtration System For Arsenic Removal

  The Toquepala mine is a large copper mine in the Tacna Province in Peru, on the border with Chile and Bolivia. The mine is situated far from nearby towns and cities and is operated by between 800-900 employees living on-site.

• Integrated Treatment System For Drinking Water

  Dominica is an island in the Caribbean Sea that was granted independence by the United Kingdom on December 3rd 1978 after many years as a British colony. The island is comprised of a black volcanic sandy coastal strip, rain forest and mountains rising to a height of over 1,400 meters. The island’s area is about 750 km2 with a population of 70,000.

• 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.

• 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.
