The Evolution and Practical Application of Scale Inhibitor Modelling and Dosage Optimization in Industrial Water Treatment

This paper discusses the development and practical application of state of the art models for controlling mineral scale formation in industrial systems. Models for scale inhibitor dosage optimization have been evolving since the 1970?s in parallel to the computerization of scale prediction methods. Increasing use of less than desirable water sources, and application over broad pH, temperature and ionic strength ranges, have increased the need for sophisticated models to allow effective economical treatment, and to minimize treatment levels and cost, while providing acceptable levels of scale control
