Reverse osmosis and nanofiltration device leakage detection method
1 Scope
This standard specifies the overall leakage detection of reverse osmosis or nanofiltration devices, membrane module leakage detection and detection methods for leak points in membrane modules.
This standard applies to reverse osmosis or nanofiltration devices equipped with rolled membrane elements in municipal and industrial water treatment systems for desalination purposes.
Leak detection, installation of other types of reverse osmosis and nanofiltration membrane components can be referred to.

3 Terms and definitions
The following terms and definitions defined in GB/T 20103-2006 apply to this document. For ease of use, the following is repeated
Certain terms and definitions in GB/T 20103-2006.
3.1
Reverse osmosis reverseosmosis; RO
Under pressure above the osmotic pressure difference, a solvent (such as water) passes through the semipermeable membrane into the low pressure side of the membrane, while other components in the solution (eg
The salt is blocked on the high pressure side of the membrane and discharged with the concentrated solution to achieve an efficient separation process.
[GB/T 20103-2006, definition 4.2.2]
3.2
Nanofiltration nanofiltration; NF
Pressure-driven, membrane separation process for removing multivalent ions, partially monovalent ions, and organic matter with a molecular weight of.200-1000.
[GB/T 20103-2006, definition 4.2.3]
3.3
Membrane element membraneelement
A membrane separation unit composed of a membrane, a membrane support, a flow channel spacer, a perforated central tube, or the like.
[GB/T 20103-2006, definition 2.2.1]
3.4
Shell housing
A container that can be loaded into a membrane element.
Note. The outer layer of the membrane element bonded with epoxy resin or the like may also be considered as a casing.
