What is FilmTec membrane?
Filmtec membrane elements provide unmatched quality in separating the contaminants from concentrated water ending with purified clean water. These membrane filtration products are exceptionally efficient in water treatment applications that include industrial, commercial, municipal, and consumer-related concerns.
How can you tell a real FilmTec membrane?
On FilmTec™ and TapTec™ reverse osmosis filters, look for the following features indicating a genuine RO product:
- Genuine RO product label with secure graphic and QR code.
- Genuine FilmTec hologram printed on the product label.
- Classic white-colored product water tubes.
How many microns is an RO membrane?
approximately 0.0005 micron
The pores in a reverse osmosis membrane are only approximately 0.0005 micron in size (bacteria are 0.2 to 1 micron & viruses are 0.02 to 0.4 microns).
How many layers are in RO membrane?
An RO membrane is composed of three layers: a bottom layer made of unwoven polyester cloth of thickness 100–200 μm to support the entire membrane, a middle layer consisting of polysulfone (PSF) or polyethersulfone (PES) of thickness 30–50 μm, and a top layer of polyamide (PA) or polyetherimide (PEI), supported by PSF …
What are the types of RO membranes?
There are two common types of membranes: cellulose acetate (CA) and thin film composite (TFC).
What does a 0.2 micron filter remove?
Abstract. Filtration of liquids through 0.2-μm filters is a common and often-used method for the removal of microorganisms from heat-sensitive solutions.
What does a 0.1 micron filter remove?
A microfiltration filter has a pore size around 0.1 micron, so when water undergoes microfiltration, many microorganisms are removed, but viruses remain in the water. Ultrafiltration would remove these larger particles, and may remove some viruses.
What is the porosity of RO membrane?
RO membranes are effectively non-porous and, therefore, exclude particles and even many low molar mass species such as salt ions, organics, etc. 2 NF membranes are relatively new and are sometimes called “loose” RO membranes.
What is the difference between 50 gpd and 75 gpd membrane?
The major difference, besides how much water they can make, is the rejection rate. Normally, the lower the GPD volume, the higher the removal rate is. The 50 GPD membrane has a 97% rejection rate whereas FilmTec redesigned their 75 GPD membranes and it now has a 99% rejection rate.
Which type of RO membrane is best?

What is membrane pore size?
The pore size of a membrane gives an indication of the median or mean size of the pores on a membrane surface. It also describes the particle size that the membranes will be able to reject, as well as characterising the membrane.
