    3、icy and Strategy Committee on 30 April 2007 BSI 2007ISBN 978 0 580 50508 9National forewordThis British Standard was published by BSI. It is the UK implementation of EN 14701-3:2006.The UK participation in its preparation was entrusted to Technical Committee EH/5, Sludge characterization.A list of o

    4、rganizations represented on EH/5 can be obtained on request to its secretary.The UK committee has never seen the need to standardize this method at a European level and, as a consequence, has not been actively involved in the development of this standard. However, the UK committee is pleased that a

    5、classic British method was selected. The method has long been used as a valuable operational-control method and is available in existing technical literature (see reference 1 in the bibliography of this standard). Due to the difficulty and cost of sending liquid sludge samples (in such a manner that

    6、 their properties do not change) to laboratories for international interlaboratory trials of the performance of this method, interested parties convened at a workshop to assess the test. Their conclusion was that the results are operationally defined (e.g. by the filter paper used) and, as the docum

    7、ent does not specify all such operational details, the performance data are not really applicable outside the context of the workshop. As a result, the members of EH/5 have no information to offer on the reproducibility of the results.This publication does not purport to include all the necessary pr

This European Standard shall be given the status of a national standard, either by publication

    17、of an identical text or by endorsement, at the latest by December 2006, and conflicting national standards shall be withdrawn at the latest by December 2006. Other parts of this European Standard are: Part 1: Capillary suction time (CST); Part 2: Determination of the specific resistance to filtratio

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

    20、bility is complementary to that of specific resistance to filtration (see EN 14701-2). The scope of this determination is to evaluate the best range of pressure to be adopted for filtration. This parameter can be used together with other parameters to evaluate the performance of full-scale filtratio

    21、n devices. Licensed Copy: Wang Bin, na, Tue Aug 21 01:03:35 GMT+00:00 2007, Uncontrolled Copy, (c) BSIEN 14701-3:2006 (E) 5 1 Scope This document specifies a method to determine the compressibility of sludges, conditioned or not. This document is applicable to sludges and sludge suspensions from: st

    22、orm water handling; urban wastewater collecting systems; urban wastewater treatment plants; treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EEC); water supply treatment plants. This method is also applicable to sludge and sludge suspensions of other origin.

    27、s of the specific resistance to filtration at least at three different pressures, following the procedure reported in the relevant method (see 6.2 or 6.3 of EN 14701-2:2006). The following values are suggested: 50 kPa, 150 kPa and 500 kPa. 7 Expression of results The coefficient of compressibility,

    28、s is related to the applied pressure p by the equation (1): sporr = (1) where rois the specific resistance to filtration at pressure = 100 kPa; r is the specific resistance to filtration at pressure p; p is the pressure drop across the cake and cloth in Pascals (Pa); s is the coefficient of the comp

    29、ressibility. Introducing logarithms, results: plogsorlogrlog += (2) Plotting on a log-log scale diagram r versus p, a straight line having a slope s is obtained. The value of s is calculated considering two points of the line r-p having respectively, co-ordinates (r1, p1) and (r2, p2) by equation (3

    30、): )1p/2p/(log)1r/2r(logs = (3) NOTE Values of s higher than 1 indicate an increase of the specific resistance to filtration more than proportional to the pressure, thus it is not convenient to operate at high pressures (see clause 6). 8 Precision Precision is referred to that of the Determination o

    31、f the specific resistance to filtration (EN 14701-2). 9 Test report The test report shall contain the following information: a) reference to this document; b) all information necessary for the complete identification of the sample; c) method with a reference to this document; d) test results obtaine
