PRODUCTS

As part of Toray’s MEMBRAY MBR series, the NHP (New High Performance) module features thin membrane flat sheets that are densely packed into easily interchangeable cassettes. These cassettes allow for a higher packing density than what was originally thought possible with flat plate designs. The thin membranes are also highly flexible and allow for more movement, resulting in increased vibrations during aeration. This helps dislodge sludge and improve cleaning efficiency, all with less energy use. 

CSM NF membranes selectively removes divalent and monovalent ions, making it ideal for a wide range of applications. Typical uses include production of food & beverage, dye recovery, and water softening and removal of specific impurities (i.e. color, DBP, THM) for potable use. CSM NF Membranes are constructed with either a polyamide or piperazine thin-film layer, and are available in various sizes. Inquire within for custom-engineered solutions.

Following 4”, 8” and 16” membranes can be used in multiple membrane systems to treat sea water or high salinity water > 10’000 ppm. The 4” membrane types can be used for small private or shipboard sea water desalination.

FEATURED ARTICLES

  • 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.

  • Taiwan Mandates Water Reclamation For Economic Sustainability

    As a leading global supplier of semiconductors and other related IT components, access to a consistent supply of clean water is essential in Taiwan for sustaining a growing economy. However, in 2015, the country experienced one of the worst droughts in its history. Combined with frequently occurring typhoons that hamper the availability of clean water, this sparked the government to implement countermeasures immediately. Read the full case study to learn more.

  • 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.

  • Seawater Desalination Using RO Membranes To Support A Thriving Agricultural Economy

    As the agriculture economy boomed, needs for freshwater demanded by irrigation, tourism and the local community also grew in Campo de Dalías, a coastal region on the Mediterranean Sea. As a result, the region faced overexploitation of groundwater aquifers. Read the full case study to learn how Toray was selected as the sole membrane supplier for a two-pass system for a newly implemented national desalination plan.

  • How To Score High Marks For Low-Pressure RO Performance

    For water system operators, contract engineers, OEMs, and reverse-osmosis (RO) membrane suppliers alike, the difference between expectations for RO membrane element performance and quantifiable performance in the actual operating environment can be fraught with surprises. This article addresses guidelines for establishing realistic RO warranty performance criteria and achieving those criteria in real-world applications.

  • How UF Membrane Fiber Strength Impacts Reuse Success

    Advanced technology and more widespread acceptance are driving a growing number of municipalities to adopt the practice of wastewater reuse. Ultrafiltration (UF) has been proven a key in this process, but operators have struggled to keep up with repairs or having to replace older hollow-fiber membranes. Recent advancements in manufacturing have produced more durable membranes that accomplish the task at a lower cost based on the total lifecycle.
