DIN EN 14652:2007-09

This European Standard applies to membrane separation systems with a particle rating below 1 mm, namely Microfiltration(MF), Ultrafiltration (UF), Nanofiltration(NF) and Reverse Osmosis(R.O.), for drinking water installations inside buildings, intended to remove from the drinking water marginal concentration of suspended and colloidal solids, microorganisms, organic molecules and to reduce the dissolved solids concentration, with a minimum pressure of PN10, connections between 15 NS and 100 NS and a maximum design temperature of at least 30 °C. It specifies requirements relating to the construction, performances and methods of testing. It only concerns units which are permanently connected to the mains supply at the point-of-entry (POE) or the point-of-use (POU). This standard applies to membrane systems, whose elements may be partly or entirely washable or disposable according to the type of system. A membrane separation system may include,together with the separation device some pre-and /or post-treatment devices.
