What condition hinders effective disinfection of water due to suspended particles?

• A. Turbidity
• B. Hardness
• C. pH levels
• D. Saturation

Answer: (A)

Turbidity refers to the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye. When water contains suspended particles, such as silt, clay, or organic material, it can significantly affect the effectiveness of disinfection processes. Effective disinfection relies on methods like chlorination, ultraviolet (UV) light, or ozone treatment, which can be hindered by turbidity. The suspended particles can shield microorganisms from the disinfecting agents, preventing them from effectively contacting and neutralizing pathogens. This shielding means that even if the disinfectant is present in adequate quantities, it may not reach and kill the microbes, leading to insufficient disinfection and potential health risks. In contrast, hardness is more related to mineral content in water, such as calcium and magnesium, and does not directly affect disinfection efficiency. pH levels can influence disinfection but primarily by affecting the form and efficacy of disinfectants rather than by directly obstructing their ability to reach microorganisms. Saturation typically relates to solubility levels of minerals in water rather than particle suspension, thus not impacting the disinfection barrier like turbidity does.
