Dow Filmtec reverse osmosis membranes TW30-1812-50 are specifically designed for home drinking water treatment. These Polyamide (TFC) Thin Film Composite, standard 1.8” diameter elements that have been tested and certified by NSF/ANSI Standard 58. It is some of the most reliable and consistent elements in the water filtration and water purification.
TW30-1812-50 RO membrane is rated at 50 Gallons per Day. If there is chlorinated water, we recommend you use a Carbon filter.
OV-FR SERIES INDUSTRIAL MEMBRANE EL EMENTS
MAIN TECHNICAL FEATURE
OV-FR series fouling membrane components are produced by qualified materials with durable, high desalination, large permeate flow components properties., OV-FR series membrane elements is designed to be easily-clean, with a wider feed water inflow conduit net. A special surface treatment is used to change the surface smoothness and the embrane material, for the purposes of increasing the membrane surface hydrophilicity. The structure of the contaminants and microbial contamination deposited on the membrane surface. Therefore, the special design improves cleaning effect, reduces the membrane element pollution and elongates service life. OV-FR series are perfect for desalination of surface water, groundwater, tap water and other low salinity water sources(s10000ppm). It is mainly used in industrial water reuse, boiler feed water and other industrial water treatment, as well as urban sewage treament and industrial wastewater which contain a small amount of organic pollutans.
