16-16: The Evolution And Practical Application Of Scale Inhibitor Modelling Standards and SpecificationsModels for scale inhibitor dosage optimization have been evolving since the 1970s in parallel to the computerization of scale prediction methods. Increasing use of less than desirable water sources, and application over broad pH, temperature and iconic strength ranges have increased the need for sophisticated models to allow effective economical treatment, and to minimize treatment levels and cost, while providing acceptance levels of scale contrail.
