Book Description
A review and summary of the basic chemistry of the formation and deposition of scale from evaporating sea water shows that the equilibrium solubility product relations of the scale constituents are of secondary importance in the prediction and evaluation of scaling rates. The quantity of scale actually deposited on the heated surfaces depends additionally upon those factors of chemical content and physical operation which determine the relative proportion of each scaling constituent. Using data obtained by operating the experimental evaporator previously described, the relations between scalling rates and the physical factors of operation are found. The corrosion of the copper-nickel and bronze alloys of the experimental evaporator is briefly reviewed. The sea water additives, Navy Boiler Compound-plus-starch and Belloid T-D have been tested using normal sea water in the experimental evaporator. Scale remaining after such treatment was reduced. It is concluded that the concept of preconcentration, developed in the preceding report, may be used with increased brine velocities, to reduce scaling rates in sea water evaporators of all types.

Book Description
The heat balance equation for the experimental sea water evaporator is developed for atmospheric evaporation, and the overall coefficients of heat transfer are presented. The major components of sea-water evaporator scale are identified. The physical deposition of suspended scale constituents is shown to affect all scale constituents, and to be more greatly influenced by brine velocity than by temperature gradient. The role of calcium sulfate as a cementing agent is discussed. The mechanism of carbonate scale formation is reviewed. A simple modification of present evaporator design is suggested to minimize the formation of carbonates. The velocity of scale deposition is influenced by operating factors other than those which proportionately affect the rate of distillation. It is therefore suggested that the use of 'scaling rates, ' - weight of scale per unit volume of distillate, be implemented by scale analyses or by a description of these operating factors in the evaluation of sea water scales. Recommendations for further research are presented. (Modified author abstract).
