Full title and description

St NACE Paper 14491-2020 — conference paper published in the CORROSION 2020 proceedings. The paper is titled "The Development of Novel Laboratory Test Method on Evaluation of Scale Inhibition and Dispersancy for Downstream Water Treatment Applications" and presents a kinetic turbidity test (KTT) method using UV-Vis monitoring to evaluate scale inhibitors and polymer dispersants for industrial cooling and downstream water systems.

Abstract

This paper describes a new laboratory approach — the Kinetic Turbidity Test (KTT) — to characterize scale formation and to evaluate the performance of scale inhibitors and dispersants. KTT uses continuous UV-Vis/turbidity monitoring to record scale formation kinetics at various inhibitor dosages, giving time-resolved data that enable minimum-dosage recommendations and insights into mechanisms. The authors compare KTT results with traditional static bottle tests and demonstrate that KTT provides faster, more objective, and richer data for selecting scale control chemistries in systems with particulates (iron oxides, clays) and variable water chemistry.

Scope

The document presents a laboratory test method (KTT) for rapid, kinetic assessment of scale inhibitor and polymer dispersant performance in industrial water systems. It covers test setup (UV-Vis/turbidity monitoring), comparison against static bottle tests, representative water chemistries and suspended solids conditions, interpretation of kinetic turbidity curves, and recommendations for using KTT data to select minimum effective dosages for downstream/cooling-water applications. The focus is on practical selection and screening of chemical treatments rather than on regulatory limits or design standards.

Key topics and requirements

• Kinetic Turbidity Test (KTT) methodology — continuous UV-Vis/turbidity monitoring to track scale formation over time.
• Comparison of KTT with traditional static bottle testing (advantages in speed, data richness, and repeatability).
• Evaluation metrics: minimum effective inhibitor dosage, rate of turbidity increase, dispersancy performance in presence of particulates.
• Test conditions and reporting: recommended sample handling, turbidity/time curve presentation, and dosage–response interpretation.
• Application guidance for downstream water treatment practitioners selecting scale control chemistries.

Typical use and users

Intended for corrosion and water-treatment researchers, laboratory analysts, chemical suppliers (scale inhibitor and dispersant manufacturers), process/water treatment engineers, and plant operations teams responsible for cooling systems and downstream water treatment. The method is used for R&D screening, vendor/product evaluation, and developing dosage recommendations for field trials and plant operation.

Related standards

Related material includes CORROSION conference proceedings and guidance published by NACE/AMPP on corrosion testing and water treatment, plus relevant ASTM and ISO test methods for water analysis and corrosion evaluation. Practitioners frequently combine KTT screening results with established corrosion test methods and water chemistry standards when developing treatment programs.
