EN 14652:2005+A1:2007 (E) 4 Introduction With respect of potential adverse effects on the quality of water intended for human consumption caused by the product covered by this European Standard, the following is
20、 pointed out to the user of this European Standard: 1) this European Standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA; 2) it should be noted that, while awaiting the adoption of verifiable European criteria, exis
21、ting national regulations concerning the use and/or the characteristics of this product remain in force. EN 14652:2005+A1:2007 (E) 5 1 Scope This European Standard specifies requirements relating to the construction, performance and methods of testing for membrane separation systems with a particle
22、rating below 1 m, namely microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) for drinking water installations inside buildings, intended to remove from the drinking water marginal concentrations of suspended and colloidal solids, microorganisms, organic molecules
23、 and/or to reduce the dissolved solids concentration and applies to systems with a minimum pressure of PN 10, connections between DN 15 and DN 100 and a maximum working temperature of at least 30 C. This European Standard applies to membrane separation systems, whose elements may be partly or entire
24、ly cleanable or disposable in accordance with the type of system. It only concerns units which are permanently connected to the mains supply at the point-of-entry or the point-of-use. A membrane separation system may include, together with the separation device pre- and /or post-treatment devices. F
25、or the scope of this European Standard: separation device shall comply with this European Standard, i.e. without pre-and/or post-treatments; where pre-and/or post-treatment devices are incorporated in the system, each of them shall conform to the relevant standard. If this is the case, the complete
26、system shall be considered as conforming as a whole. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、crobiological substance or parameter in drinking water 3.7 cross-flow filtration mode of operation by which part of the water passes through the membrane (product water) and the remaining part is rejected (reject water) NOTE 1 The reject water, which can be wasted or partly recycled, plays the major
37、 role of keeping the membrane surface clean. NOTE 2 Term “tangential flow“ has the same technical meaning. 3.8 daily production volume of product water produced by the system per day 3.9 dead-end filtration mode of operation in which all the water feed passes through the membrane (no reject water).
38、Depending on the rate of fouling/clogging of the membrane due to the retained substances, this filtration method is subject to declining rate of flow due to build up of retained matter.
