WILMINGTON, MA, June 15, 2005 -- Koch Membrane Systems Inc. (KMS), a developer and manufacturer of innovative membrane filtration and separation systems, has received certification of compliance with NSF/ANSI Standard 61 for nanofiltration (NF) and reverse osmosis (RO) elements. These include the Fluid Systems® TFC®SR®2, TFC-S, TFC-HR, TFC-XR, and TFC-ULP® membrane types. Certification was provided by NSF International.
The certified NF elements include both TFC-S "Softening" and TFC-SR2 "Selective Rejection" membrane types. Both membranes are effective in removing hardness, organics (i.e. disinfection by-product precursors) and color at low operating pressures. The SR2 membrane allows more monovalent ions to pass through the membrane, reducing operating pressure requirements and brine concentration.
The certified brackish water RO elements include the TFC-ULP, TFC-HR, and TFC-XR membrane types. The TFC-ULP element is an "Ultra-Low Pressure", high rejection membrane, making it attractive for municipal drinking water applications where high permeate quality and low pressure operation and the associated energy savings are primary considerations. The TFC-HR "High Rejection" membrane provides high salt rejection and fouling resistance compared to other low pressure RO membranes. The TFC-XR membrane is an excellent choice for high purity water applications where high silica and TOC removal are primary considerations or in applications where high quality permeate is required from a high salinity brackish feed. Operating in the 250-400 psi range, the TFC-XR membrane is also an excellent replacement option for higher pressure cellulose acetate (CA) membranes.
KMS also offers a broad line of antiscalants and several cleaners that have been certified to NSF/ANSI standard 60.
All KMS chemical formulations are carefully reviewed by its process engineers and membrane and polymer scientists to ensure that they will provide enhanced performance benefits, including physical and chemical compatibility with KMS membranes. KochKLEEN® cleaners and storage solution, and KochTREAT® antiscalants help prolong membrane life and reduce cleaning cycle time.
