D1291-17 – Standard Test Method Technical Guide
🧪 Scope and Significance of D1291-17
ASTM D1291-17 (Reapproved 2023) is a standardized practice under the jurisdiction of Committee D19 on Water. It provides a reliable, empirical method for estimating the chlorine demand of water, a critical parameter for effective water treatment. This practice is used to determine the correct chlorine dosage required to achieve specific treatment goals, including disinfection, control of microorganisms, oxidation of organic matter, and reduction of biochemical oxygen demand (BOD). It is broadly applicable to potable water, wastewater, and industrial process water.
The standard explicitly acknowledges that the chlorination process is highly dependent on variables such as temperature, pH, initial chlorine dosage, and contact time. This practice is designed to allow users to systematically evaluate the effects of these variables to optimize their treatment strategies for maximum efficiency and efficacy.
