1、Designation: D 5905 98 (Reapproved 2003)Standard Practice forthe Preparation of Substitute Wastewater1This standard is issued under the fixed designation D 5905; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi
2、sion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the preparation of an aqueousmixture containing constituents in concentrations such that itwill have phys
3、ical and chemical matrix characteristics similarto municipal wastewater.1.2 Wastewaters are extremely variable, depending on thequantity and nature of the materials being discharged into thecollection system. The mixture prepared with this practice isnot representative of any particular wastewater.
4、Rather, itallows the user to prepare a mixture that exhibits a similarmatrix impact on test method performance as is typical ofmunicipal wastewater and can be prepared from commonmaterials inexpensively and reproducibly. It allows the evalu-ation of test methods, over time, against the same referenc
5、epoint.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Refer

Significance and Use4.1 Substit
8、ute wastewater may be used for laboratory testingwhere a reproducible mixture simulating municipal wastewateris required. To provide a more rugged evaluation of a testmethods ability to measure analytes and the precision of thetest method under more demanding conditions, it is necessaryto utilize a
9、matrix more complex than reagent water. Substitutewastewater is intended to be used as a material to be spikedwith analytes or interferents of interest to evaluate the perfor-mance of test methods.4.2 Utilization of substitute wastewater as a matrix ininterlaboratory validation studies will allow in
10、clusion of per-formance statistics for this matrix in the Precision and Biassection of test methods. Users of test methods will be able toevaluate their application of test methods in this matrix againstpublished results.5. Apparatus5.1 Blender, household or commercial variety, with achemically iner
