Book Description
Many of the difficulties that arise during the industrial use of water are closely related to water-formed sludges, scales, and corrosion products. The composition of such deposits can be interpreted to provide a guide for practical preventive treatment of either the water or its environment. In the proper hands, complete and detailed information concerning water-formed deposits can be useful; unless this information is accurate, however, it can be misleading. Accordingly, reliable methods should be available for the analysis of carefully selected samples. The chemical analysis of water-formed deposits presents a challenge to the analyst's skill and causes him to muster all the knowledge of his profession. The usual quantitative analysis will yield the elemental composition of the major constituents of such deposits, but other tools must be used to determine accurately the combinations of these elements. These include the spectrograph, biological and petrographic microscopes, and X-ray diffraction equipment described in Chapter VIII. 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.

Book Description
Pure water in an uncorrodible vessel would never leave a deposit. Although this ideal case has been very nearly reached in some instances, deposits are still found in most water or steam systems. The examination and analysis of these deposits provides the person responsible for water treatment with information about phenomena in the water system, and will frequently indicate to him the means for correcting the condition that caused the deposit. This chapter covers the nature of water-formed deposits, the sampling of deposits for analysis, and methods for identification of the constituents of a deposit. Quantitative chemical analysis is dealt with in Chapter IX. Some of the instrumental methods discussed in this chapter are not at present widely used in the examination of water-formed deposits, but brief descriptions are included because there are instances where they can be used to advantage. Deposits may be divided into three general classes: inorganic, organic, and biological. Inorganic deposits result from corrosion of containing surfaces; from precipitation by chemical reaction between two or more constituents of the water; or precipitation from physical causes, such as change in solubility with pressure or temperature, by evaporation to dryness, or by relief of supersaturation. Closely akin to these, but still somewhat distinct, is the sedimentation of suspended matter.

Book Description
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.

Book Description
Water-Formed Deposits: Fundamentals and Mitigation Strategies wholly presents the important issue of deposits in aqueous systems, both industrial and biological. By analyzing causes, mechanisms and mitigation strategies, the book helps researchers/engineers/end-users gain a fundamental understanding of the issues underlying deposit formation and mitigation. It covers numerous, fundamental aspects of water-formed deposits, while also giving an applications’ perspective. The book's goal is to assist the reader in his/her understanding of the important issues of scale formation, while also helping with potential solutions. Provides a fundamental understanding of deposit formation by presenting basic science and mechanisms Presents an “applications perspective Reveals a systematic overview of deposit-related challenges and their mitigation Correlates structure to performance in mitigation strategies Analyzes current legal aspects and regulations Includes case studies from the “real industrial world for the industrial reader/end user
