--

The Reverse Osmosis Membrane element is designed for the treatment of low-salinity water resources such as tap water, well water, etc. Working under extra-low pressure, it is applicable to water purifying devices for residence, hospitals, and laboratories.

Notes: Permeate of a single element may vary within [-20%] ~ [+20%]

Dimensions: 1.0 inch = 25.4 mm

TESTING CONDITIONS:

• Testing Pressure ………………………………… 60 psi (0.41MPa) (0.41MPa)


• The temperature of Testing Solution ……………….. 25℃


• The concentration of Testing Solution (NaCl) ……… 250 ppm


• the pH of Testing Solution ………………………….. 6.5~8.5


• Recovery of Single Element……………………. 15%

Reverse osmosis (RO) membrane elements for home drinking water are the industry’s most reliable. Advanced membrane technology and automated fabrication allow these elements to deliver consistent performance that equipment suppliers, water treatment dealers, and residential customers can rely on. Membrane elements are shipped dry for convenient handling and long shelf-life. These elements are NSF/ANSI Standard 58 listed.

Equipment suppliers can take advantage of the membrane's Standard 58 listing and participation in the NSF Data Transfer Protocol to reduce costs for reduction claims for their systems. Reverse Osmosis home drinking water elements are rated a 50 psi and will purify about 20% more water than competitive elements rated at 60 psi (please see reference charts on page two for more information).

2. Refer to Cleaning Guidelines in specification sheet 609-23010.


3. Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure.Since oxidation damage is not covered under warranty, FilmTec recommends removing residual free chlorine by pretreatment prior to membrane exposure. Please refer to technical bulletin 609-22010 for more information.
