Product Description Model NO.: LCHR-4040 Application: Industry, Food and Beverage, Medicine, Textile, Metallurgy Trademark: Filmtec HS Code: 8421999000 Material: Chemical Fiber Filtration Grade: Medium Filter Origin: USA What is Reverse Osmosis? 
Reverse osmosis (R/O) is a water treatment process in which water is forced through a semi-permeable membrane that has very small holes or "pores". Clean water passes through and impurities that are too big to pass through the membrane are left behind and flushed away. 

How Does Reverse Osmosis Work? 
Reverse osmosis systems purify water by forcing pressurized water through a very fine, plastic membrane. If the raw water being treated comes from a well or another private source, disinfection and pre-filters (to remove chlorine and/or particulates/sediment) may be needed in advance of the R/O unit to remove contaminants that can foul or damage the membrane. 

FilmTec Corporation is a subsidiary of The Dow Chemical Company and part of the Dow Water & Process Solutions business. They make high-quality Dow FilmTec reverse osmosis and nanofiltration elements for a wide variety of industrial, municipal and commercial water applications. 

FilmTec elements from Dow feature a spiral wound design and are based on the FT30 thin-film composite polyamide membrane, which has long been the industry standard for RO performance. The FilmTec FT30 membrane consists of three layers: An ultra-thin polyamide barrier layer, a microporous polysulfone interlayer, and a high-strength polyester support web. The FT30 membrane has been continuously updated and refined to provide higher rejection, improved membrane flux, and low fouling performance. Today's FT30 membrane is uniquely uniform in performance and quality, without the taped or glued defects that can cause other membranes to fail. Good understanding and execution of the basics of reverse osmosis can minimize troublesome and costly problems in the future. Consult these tools to get a detailed understanding of the effects of feed pressure and operation parameter changes on the performance of an RO membrane system.
