Various Laboratory test procedures have been used to develop profiles and models of minimum effective dosage as a function of water chemistry, temperature and time. Some procedures provide realistic data, directly applicable to operating systems. Others that have been used and published serve only as generators of marketing data under conditions no sane water treatment chemist would run, with performance no customer would accept. This paper discusses the development of standard test procedures for simulating calcium carbonate scale control in operating systems.

This study and paper is the first in a series on test procedures for calcium carbonate, calcium phosphates, calcium sulfate, barium sulfate, and the elusive culprits silica and magnesium silicate.
