Dow Filmtec RO Membrane TW30-1812-50HR, BW60-1812-75, TW30-1812-100HR/FR Option

Note 1 : For international buyers purchasing the membrane with no flow restrictor or capillary flow restrictor, contact us before purchase as shipping cost is significantly lower than when purchasing with barrel style flow restrictor. Alternatively, we offer each membrane with capillary flow restrictor for reduced shipping cost . Listing ID numbers for each membrane are provided below. TW30-1812-50HR: 153976200978 BW60-1812-75HR: 153976205709 TW30-1812-100HR: 153976207699 Note 2: Membranes ordered with flow restrictors are shipped with the following. If you require a different size, notify us PRIOR TO SHIPMENT. Otherwise, the customer will assume all cost associated with replacement. TW30-1812-50HR: 525 cc/min capillary or 550 cc/min barrel BW60-1812-75: 730 cc/min capillary or 800 cc/min barrel TW30-1812-100HR: 1000 cc/min capillary or 1000 cc/min barrel Authentic NEW DuPont Filmtec (formerly Dow Filmtec) TW30-1812-100HR (NEW-replaces TW30-1812-100), BW60-1812-75 (NEW-replaces TW30-1812-75), and TW30-1812-50HR (NEW-replaces TW30-1812-50) Reverse Osmosis Membranes with QR anti-counterfeiting code. Simply download the DUPONT water app to your smartphone and scan the membrane to verify authenticity/obtain the membrane serial number. Each membrane can be purchased with either a capillary (internal) or barrel type (external) flow restrictor, sized for the membrane, for a small upcharge. We recommend replacing the flow restrictor each time the RO membrane is changed. Filmtec is the #1 selling membrane is the world, delivers up to 20% greater output than other membranes of comparable size, and has a typical membrane life of 3-5 years (versus 1-2 years for competitor brands). Maximum Operating Temperature 113°F (45°C) Maximum Operating Pressure 150 psig (1 0 bar) Maximum Feed Flow Rate 2.0 gpm (7.6 lpm) pH Range, Continuous Operation 2 – 11 Maximum Feed Silt Density Index (SDI) SDI 5 Stabilized salt rejection 98% (performance measured by manufacturer at 250 ppm NaCl, 77F, and 15% water recovery) Free Chlorine Tolerance < 0.1 ppm Maximum temperature for continuous operation above pH 10 is 95 F (35 C). Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Sin ce oxidation damage is not covered under warranty, Dow Water & Process Solutions recommends removing residual free c hlorine by pretreatment prior to membrane exposure. Please refer to technical bulletin "Dechlorinating Feedwater" for more information. Actual membrane performance may vary, dependent on a number of factors outside of our control (water temperature, water pressure, water source, water contaminants, TDS, silt index, pH, alkalinity). Typical % rejection, based on TDS, is 95-98%. We guarantee the membranes to be authentic Filmtec membranes, manufactured in the USA. To verify authenticity download the Dupont Water App from the App store. Scan the membrane. The scan will authenticate the membrane and provide the membrane serial number. The membrane serial number and date of purchase are required for any warranty claim filed with Dow Filmtec. WE DO NOT ACCEPT RETURNS FOR OPENED PACKAGES OF FILMTEC MEMBRANES. RETURNS ARE ACCEPTED FOR FILMTEC MEMBRANES IN THE ORIGINAL UNOPENED PACKAGE ONLY. AUTHENTICITY OF THE MEMBRANE CAN BE VERIFIED BEFORE REMOVING PACKAGING.
