Nano Filtration RO Membrane

Waterfiltec Nanofiltration membrane elements are designed for process applications where a separation of solutes is desired.

Nanofiltration membrane is a durable polypiperazine amide membrane designed to reject organics with a molecular weight above 200 while passing monovalent salts.

Our Nanofiltration membrane elements are used in a variety of applications such as desalting organic compounds, acid processing, metal recovery and antifreeze recovery.

Remarks

Depending on the application requirements, new Nanofiltration spiral elements may be cleaned prior to initial use. The cleaning procedure should be based on the application for which the elements are to be used. If cleaning with formulated agents is not available, an alkaline wash with wetting agent is recommended prior to initial use.
