This book was released on 1960 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: (A) This method describes a procedure for the examination of water-formed deposits by means of chemical microscopy. The procedures of chemical microscopy are applicable to all water-formed deposits. They are much less time consuming than chemical macroanalysis, and, when they can be supplemented by optical data, sufficient information may be obtained to make complete chemical analysis unnecessary. The sample required is small. The method can be applied in cases where there is not sufficient sample available for a macroanalysis. (b) The petrographic procedure which is a part of this method is limited to deposits that are composed of individual particles or crystals having a diameter of at least 10 μ, unless the particles have a characteristic form, cleavage, or highly specific identifying optical properties.

Book excerpt: Many of the difficulties that arise during the industrial use of water are closely related to water-formed sludges, scales, and corrosion products. These water-formed deposits are the accumulations of insoluble material derived from the water, or are formed by the reaction of water with surfaces in contact with it. The composition of such deposits can be used to diagnose the reason(s) for deposition, to determine preventive treatment of either the water or its environment, and to effect their removal. A thorough and accurate analysis is an important beginning in this process. The analysis of water-formed deposits must be versatile and comprehensive in order to handle the most complex sample. It must also be flexible enough to handle the simplest samples easily and efficiently. The usual quantitative analysis will yield the elemental composition of the major constituents of such deposits. When single elements or simple compounds predominate, such an analysis is probably sufficient. For more complex deposits, however, other tools must be used to determine accurately the combinations of these elements. These include emission spectroscopy, X-ray diffraction, X-ray fluorescence, electron probe microanalysis, flame photometry, atomic absorption, petrographic microscope, and the electron microscope. A method for atomic absorption and spectrographic analysis is outlined in ASTM Testing Water-Formed Deposits (Method D 2331) [1]; a procedure for identification by X-ray diffraction is dealt with in ASTM Test for Identification of Crystalline Compounds in Water-Formed Deposits by X-Ray Diffraction (Method D 934) [1]; X-ray fluorescence is covered in ASTM Analysis of Water-Formed Deposits by X-Ray Fluorescence (Method D 2332) [1]; flame photometry in ASTM Test for Sodium and Potassium Ions in Industrial Water and Water-Formed Deposits by Flame Photometry (Methods D 1428) [1]; and microscopy in ASTM Examination of Water-Formed Deposits by Chemical Microscopy (Method D 1245) [1]; These and other instrumental techniques are also discussed in Chapter 13. It is often possible to determine the source or cause of water-formed deposits from the results of chemical and physical analyses. The treatment for removal or prevention of such deposits can thus be accomplished scientifically instead of by trial and error.

This book was released on 2005 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: So that engineers can respond to consumer complaints about particulate matter in drinking water, this manual provides a series of decision trees for selecting an analysis process, and describes wet chemical methods for making qualitative identifications of aluminum, copper, iron, lead, manganese, and zinc contaminants along with advanced methods for confirming results. Preparation of reagents required for each wet chemical method and procedural instructions are listed on the left-hand page, while color images are reproduced on the right.

Book excerpt: This method describes the manner in which the results of examination and analysis for inorganic constituents of deposits formed from industrial waters are to be reported. Note 1.--All analyses are to be made in accordance with the methods of test of the American Society for Testing Materials, unless otherwise specified. Note 2.--While various other methods of reporting the analysis of water-formed deposits are in use, this method is intended as a rational and comprehensive practice for general application. For use in specific industries or individual cases, molecular combinations may be useful and desirable.
