It is that dissolved matter that is capable ofpassing through a glass fiber filter and dried to constant weight at 180C, as determined by following the procedures outlined inthis test method.3.2.2 nonfilterable matteralso commonly

18、known as total suspended solids (TSS). It is that particulate matter that is retainedon a glass fiber filter and dried to a constant weight at 103 to 105C, as determined by following the procedures outlined in theisetest methods.3.2 Definitions of Terms Specific to This Standard:3.2.1 filterable mat

It is that dissolved matter that is capable ofpassing through a glass fiber filter and dried to constant weight at 180C, as determined by following the procedures outlined inthis test method.3.2.2 nonfilterable matteralso commonly known a

20、s total suspended solids (TSS). It is that particulate matter that is retainedon a glass fiber filter and dried to a constant weight at 103 to 105C, as determined by following the procedures outlined in thesetest methods.4. Significance and Use4.1 Solids, both as filterable matter (TDS) and nonfilte

21、rable matter (TSS), are important in the treating of raw water andwastewater, and in monitoring of streams.4.2 Waste solids impose a suspended and settleable residue in receiving waters. Suspended and soluble materials provide amatrix for some biological slime and, in sufficient quantity, impair res

22、piration of organisms.These solids may create nuisance slimebeds and odors while imposing a long-term biological oxidation load over limited receiving water areas.4.3 Knowledge of suspended and soluble materials is important in treating raw water supplies. Knowledge of solids loading canaid in deter

23、mining the type or amount of treatment, or both, necessary to make the water acceptable for use. Such information mayalso be used to determine acceptability of water after treatment.Too little treatment may not be desirable and excess treatment costsmoney.4.4 Stream monitoring is important for envir

24、onmental reasons, such as compliance with discharge permits. Streamimprovements, water pollution monitoring, mass wasting, algal studies, and sediment loads are but a few of the many reasonsstreams are monitored.5. Interferences5.1 For some samples, chemical reactions may cause some materials to cha

25、nge from one phase to another. For example, in somegroundwaters, ferrous ions may form insoluble ferric hydroxides. Softened water high in carbonates may precipitate calciumcarbonate. In such cases, holding time may have a critical impact upon both the filterable and nonfilterable matter. Such sampl

26、esmay have to be filtered in the field.5.2 This test method is not meant to include nonrepresentative particulates such as leaves, sticks, insects, fish, etc. These shouldbe removed before the analysis.5.3 Certain materials may be measured poorly, or not at all. Some materials may decompose or volat

27、ilize at the requiredtemperature. Other substances, such as glycerin or sulfuric acid, will remain liquid at the required temperature, giving variableresults. Oils and greases may present similar problems and can end up in either the filterable (TDS) or nonfilterable (TSS) portion.5.4 Suspended soli

28、ds samples high in dissolved matter, such as saline waters, brines, and some wastes, may be subject to apositive interference by the retention of dissolved matter, such as salts and sugars, on the filter. Care must be taken in the finalrinsing of the filter so as to minimize this potential interfere

29、nt. Additional washing may be necessary.5.5 Clogging of the filter with too fine or too much material will prolong the filtering time and retain smaller particles that wouldnormally pass through the filter, thus giving elevated values to nonfilterable matter (TSS) and low values to the filterable ma

30、tter(TDS). Biological material, such as algae, may also prolong filtration time or plug the filter.D5907 1325.6 Some samples may be hygroscopic, requiring prolonged drying, extra careful desiccation, and rapid weighing. For filterablematter (TDS), samples highly mineralized or high in bicarbonate ma

31、y require careful and possibly prolonged drying. For thebicarbonate, the extended drying may be needed to ensure complete conversion to carbonate.5.7 Too much material retained on the filter may entrap water, and may also require extended drying time for the suspendedsolids. For filterable matter (T

32、DS), excessive residue in the dish may cause the formation of a water-trapping crust, giving elevatedvalues.5.8 For some users, certain biological materials, such as algae, slimes, insects, or other small crustaceans, may be consideredto be positive interferences for nonfilterable matter (TSS). Modi

33、fications or adjustments may be needed to generate a better value.An example is determining chlorophyll content to estimate the amount of algae present. Such modifications may be beyond thescope of this test method.6. Apparatus6.1 Analytical Balance, capable of measuring to the nearest 0.1 mg.4 For

34、the high precision total dissolved solids method, therecommended balance should have a capacity of 200 g and be capable of measuring to the nearest 0.01 mg.6.2 Drying Oven, capable of maintaining a temperature between 103 and 105C and between 178 and 182C .182C.NOTE 1To prevent dust and sample from

35、being blown around, it is preferred that the oven for the particulate matter (TSS) be of a gravity convectiontype. If this is not possible, samples should be shielded from the forced air of mechanical convection ovens.6.3 Evaporating Dishes, 70-mL to 250-mL capacity, not to exceed 200 g in weight.6.

36、4 Glass Fiber Filters, without organic binder.5 47-mm diameter filters are needed for the high precision TDS method whenfield filtration is not utilized.NOTE 2Although there is no organic binder in these filters, they may contain a wet strength resin that is partially soluble. It is therefore import

37、antto adequately prewash the filters as prescribed.6.5 Membrane Filter AssemblyA borosilicate glass, stainless steel, or plastic funnel with a flat, fritted, or grid base so as toprovide uniform support and filterable surface. The top section of the funnel shall fit over the edge of the filter to pr

38、ovide a seal.The top should be removable to allow easy access for removing the filter. A Gooch crucible with a fritted bottom may be used inlieu of the funnel. A 47-mm filter assembly is needed for the high precision TDS method when field filtration is not used.6.6 Planchet or Pan, made of aluminum

39、or stainless steel, capable of supporting the filter when it is not on the filter assembly.6.7 Vacuum Source.7. Reagents and Materials7.1 Purity of WaterUnless otherwise indicated, references to water shall be understood to mean reagent water conforming toType I or II of Specification D1193. Type II

40、I or IV may be used if they effect no measurable change in the blank or sample.8. Hazards8.1 Care must be taken to ensure filter funnels and filtering flasks are in a sound state. Any tiny nick, scratch, or weakness inglass flasks or other apparatus can create a potential for an implosion hazard. Wr

41、apping a flask is not adequate protection in caseof an implosion. It is recommended that a solid shield, such as a plexiglass cage, be placed around any filtering flask.9. Sampling9.1 Collect the sample in accordance with the applicableASTM standard as follows: Specification D1192 and Practices D337

42、0.9.1.1 If sampling is required from an open channel flow, use Guide D4411 and Test Methods D3977 on a separate sample bottleto determine the sediment concentrations instead of the TSS.9.1.2 The user of the method is advised to use a slurry rotary sample divider to obtain reproducible aliquots of su

43、spended solidsfor the TSS determination.69.2 If theTDS concentration is shown to change as a function of time more than the repeatability measured in the interlaboratorytesting of the method for a particular sample matrix, it will be necessary to filter the sample in the field and transfer the sampl

44、evolume needed for the high precision TDS method to refrigerated sample collection bottles.4 The balance prescribed in this test method should be tested periodically according to Practice E319 or Test Method E898.5 Millipore AP-40, Whatman 934-AH, Gelman type A/E, or equivalent, was specified for th

Summary of Test Method10.1 Awell-mixed samp

47、le is filtered through a weighed standard glass fiber filter. The suspended solids are retained on the filter,which is dried at 105C and weighed. The increased mass on the filter represents the nonfilterable matter (TSS).10.2 The filtrate from 10.1 may be used to determine the filterable matter (TDS

48、).The filtered sample (liquid phase) is evaporatedto dryness and heated to 180C in a tared vessel to a constant weight.11. Procedure11.1 Prepare the glass fiber filters before use.11.1.1 Place the glass fiber filter on the membrane filter assembly, or insert into the bottom of a suitable Gooch cruci

49、ble, withthe wrinkled surface up. While a vacuum is applied, wash the disc with three successive volumes of water. Each volume of watershould be equal to 3 mL for each square centimetre of filterable surface area. For standard 47 mm 47-mm filter holders with 35mm 35-mm diameter funnels, this would be 30 mL for each wash for a total of 90 mL. Continue the vacuum until the free waterhas been removed. Discard the washings.NOTE 3Proper washing is important for removing loose fiber and wet strength resins. One 90-mL wash is not as effective as three 30
