✦ Synopsis

A Sfudy jS ma& of the mechanism of CaC0.a scale deposition on hat exchanger surfaces. occurring in the turbulent flow of wntcr containing dissolved scale constituents under non-boiling conditions. A general rate model is presented which takes into account physical and chemical steps involved in scale deposition. Controlling mechanisms are elucidated by examining the dependence of scale growth rate on the pertinent basic parameters: tlow velocity, scale surfacc temperature and \atct composition. Scale growth-rate varies with (Reynolds number) . 0 65 and is only slightly dependent on surface

Cellulose powder was found to be a substrate favoring the deposition of calcite crystals from stable supersaturated solutions at pH 8.50 and at 25 β€’ C. Kinetic analysis of the initial rates showed that they were proportional with the relative supersaturation with respect to calcite. Analysis of the
