As turbidity levels decrease, what becomes more effective?

As turbidity levels decrease, chlorine disinfection becomes more effective due to the clearer water allowing for better contact between chlorine and any pathogens present. In water treatment, turbidity can interfere with disinfection processes by providing a barrier that protects microorganisms from the disinfectant. When turbidity is high, particles in the water can shield pathogens, making it more difficult for chlorine to act effectively. However, as turbidity is reduced, there are fewer particles to obstruct the chlorine, allowing for more efficient disinfection. This enhanced interaction leads to a higher likelihood of successful pathogen inactivation, resulting in safer drinking water.

The other methods mentioned may have different effectiveness under varying turbidity conditions, but they do not directly relate to the same mechanism of disinfection as chlorine. For instance, while filtration improves with lower turbidity for removing particulate matter, the focus of this question is on the specific effectiveness of disinfection methods, making the enhancement of chlorine disinfection the most pertinent outcome as turbidity decreases.
