25、14-06 EN 16070:2014 (E) 5 1 Scope This European Standard is applicable to natural zeolites used for treatment of water intended for human consumption. It describes the characteristics of natural zeolites and specifies the requirements and the corresponding test methods for natural zeolites. It gives
26、 information on their use in water treatment. The natural zeolites included in this standard are clinoptilolite, chabasite and phillipsite/analcime. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applicat

32、e over 200 different zeolites with about 30 natural zeolites. However, not all natural zeolites can be used in the treatment of water intended for human consumption. Given the particular characteristics needed for this type of application, only three species are identified: clinoptilolite, chabazite
33、 and phillipsite/analcime. These zeolites are available in large quantities in Europe, with no trace of hazardous or toxic elements. 5 Physical properties 5.1 Appearance The product consists of dry, free flowing granules. The product has a granular shape and a rough texture. The product shall be gen
34、erally homogeneous and shall be visibly free of extraneous matter. 5.2 Particle size distribution The particle size distribution shall be determined on samples taken at the point of manufacture using the method of test given in EN 12902. NOTE 1 The particle size can decrease during transportation an
35、d handling. The particle size distribution shall be described by either: a) effective size: (d10) with a maximum deviation of 5 %; median size: (d50) with a maximum deviation of 5 %; 1)Chemical Abstracts Service Registry Number. 2)European Inventory of Existing Commercial Chemical Substances. DIN EN
36、 16070:2014-06 EN 16070:2014 (E) 7 uniformity coefficient: (U) shall be less than 1,5; minimum size: (d1) with a maximum deviation of 5 %; or b) by particle size range and by mass fraction of oversize and undersize particles (see A.2.2.1). The maximum permitted mass fractions of oversize and undersi
37、ze are 5 %. NOTE 2 Other values might be necessary for certain applications. 5.3 Density (bulk density loose) The bulk density loose shall be in the range of: 800 kg/m3to 1 100 kg/m3for a clinoptilolite type zeolite; 700 kg/m3to 850 kg/m3for a chabazite type zeolite; 1 000 kg/m3to 1 100 kg/m3for a p
38、hillipsite/analcime type zeolite. 6 Chemical and mineralogical properties 6.1 General This European Standard specifies the minimum purity requirements for natural zeolite used for the treatment of water intended for human consumption. Limits are given for impurities commonly present in the product.
39、Depending on the raw material and the manufacturing process, other impurities may be present and, if so, this shall be notified to the user and when necessary to relevant authorities. Users of this product should check the national regulations in order to clarify whether it is of appropriate purity
40、for treatment of water intended for human consumption, taking into account raw water quality, contents of other impurities and additives used in the product not stated in this product standard. Limits have been given for impurities and chemical parameters where these are likely to be present in sign
41、ificant quantities from the current production process and raw materials. If the production process or raw materials lead to significant quantities of impurities, by-products or additives being present, this shall be notified to the user. The composition of the commercial product shall conform to Ta
42、ble 1. Table 1 null Composition of commercial product Parameters Limit in mass fraction % Mass loss at 150 C max. 7 Ignition loss at 650 C max. 14 After filling, washing and commissioning of a filter system producing drinking water, natural zeolite should not increase the concentrations of chemical
43、parameters (see1). NOTE Water extractable substances, determined in accordance with the method for granular materials given in EN 12902, can be used to estimate the leaching of the chemicals specified in EN 12902. DIN EN 16070:2014-06 EN 16070:2014 (E) 8 6.2 Capacity The cations that maintain the el
44、ectronic neutrality of the zeolite structure can be exchanged. This is a selective cation exchange according to the zeolite affinity for the replacing cation. The total cation exchange capacity and the selectivity are specific to each type of zeolite. This property makes the zeolites especially usef
45、ul and efficient for cation elimination or to achieve control of their concentration in water. Ammonium can be used as a quality standard to determine the Cation Exchange Capacity (CEC) of a natural zeolite. The total CEC shall be not less than 1,2 mg of ammonium per gram zeolite. 7 Test methods 7.1
46、 Sampling Prepare the laboratory sample(s) required by the relevant procedures described in EN 12902. 7.2 Analysis 7.2.1 Particle size distribution The particle size distribution shall be determined in accordance with EN 12902. 7.2.2 Bulk density loose The bulk density loose shall be determined in a
47、ccordance with EN 12902. 7.2.3 Mass loss at 150 C It is assumed that water is the only material present in the natural zeolite that is volatile at this temperature. The mass loss shall be determined by the method for water content, heating to 150 C, in accordance with EN 12902. 7.2.4 Precision - rep
48、eatability limit The absolute difference between two single test results, obtained under repeatability conditions, shall not exceed the repeatability limit, r, in more than 1 in 20 cases. 107,0 Xr = (1)where X1is the measured value. 7.2.5 Ignition loss at 650 C 7.2.5.1 Principle Heat the sample to c
49、onstant mass at 650 C. It is assumed that water, including chemically bound water and carbon dioxide produced from carbonates, are the only materials present in natural zeolite that are volatile at this temperature. At 650 C, the loss of water is practically complete.
