Under optimum conditions, what percentage of filtration efficiency can be expected?

95%
99%
99.5%
100%

The correct answer is: 99.5%

Under optimal conditions, a filtration system can achieve a filtration efficiency of approximately 99.5%. This high level of efficiency is typically attributed to the advanced technological processes used in modern water treatment facilities, which are designed to significantly reduce the number of particulates, pathogens, and contaminants in the water. Achieving 99.5% efficiency means that the system is able to remove the vast majority of unwanted substances, making the water safer for consumption. This level of efficiency helps ensure compliance with health and safety regulations and contributes to the overall quality of the drinking water supplied to the public. The options reflecting lower percentages, like 95% or 99%, represent realistic efficiencies for less advanced filtration systems or may consider different conditions, such as variations in water quality or age of the filtration media. The choice of 100% indicates a theoretical scenario rather than a practical expectation, as it is virtually impossible to remove every single contaminant from water completely. Thus, aiming for, and achieving, a filtration efficiency near 99.5% under ideal situations provides an optimal benchmark for drinking water quality.
