Full Description

A water chemical model involving the complexion and solubility equilibria of calcium, magnesium, zinc, iron, manganese, silica, chloride, orthophosphate, and carbonate has been developed and applied to laboratory pipe-loop-coupon and field data on asbestos-cement pipe. Calculation of the saturation states of the relevant solids enables preparation of graphic guides for the prediction of dosage levels for in-situ pipe coating by zinc compounds as well as protection afforded by coatings formed by natural inhibitory constituents of the water. Environmental impacts of zinc treatment, aggressiveness index, and A-C pipe coupon tests are discussed. Includes 91 references, tables, figures.
