What is the purpose of conducting a post-installation chlorination at 50mg/l for 24 hours?

Conducting a post-installation chlorination at 50 mg/l for 24 hours serves primarily as a disinfection procedure to ensure that any potential pathogens or contaminants are eliminated from the water line following installation or repairs. This high concentration of chlorine acts as a powerful germicide, effectively killing bacteria, viruses, and other microorganisms that may have entered the system during maintenance activities.

As the chlorine maintains its effectiveness for a specified duration, it allows for thorough contact with all surfaces within the water line, increasing the likelihood that biofilm, or any other residual microbial presence, is eradicated. Ensuring the water line is sanitized is critical for public health and is part of best practices in water system management.

While addressing the other choices, enhancing the flavor of the water isn't a primary motivation for chlorination; instead, chlorine's taste can be considered undesirable. The reduction of biofilm is a secondary benefit of disinfection, but the main goal of chlorination in this context aligns directly with ensuring the integrity and safety of the water supply. Furthermore, increasing water pressure is unrelated to chlorination procedures and is controllable through different system management techniques, not through chemical treatment.
