Which method can chlorine be added to water for initial pipeline disinfection?

Adding chlorine to water for initial pipeline disinfection can effectively be done using tablets. This method involves using solid chlorine compounds that dissolve in water and release chlorine, which is a powerful disinfectant. The use of tablets allows for a controlled release of chlorine, ensuring that the water being treated maintains adequate disinfectant levels for effective microbial control throughout the pipeline.

Chlorine tablets are advantageous because they are easy to handle, measure, and store. They provide a consistent dose of chlorine and can be used in various situations where precise management of chlorine levels is necessary. This makes tablets a preferred choice for initial disinfection in water distribution systems, as they help establish a chlorine residual that can protect the integrity of the water supply.

In contrast, other methods like segmented, low dose, or air injection may not be as effective or practical for initiating a strong and immediate disinfection process in pipelines, as they may not achieve the necessary chlorine concentration uniformly across the system.
