A » Silt Density Index (SDI) is crucial before membrane filtration because it measures the potential for particulate fouling in the water. High SDI values indicate a higher concentration of particulates, which can clog membranes and reduce efficiency. Therefore, assessing SDI helps in determining the need for pre-treatment processes, ensuring optimal performance and longevity of the filtration system.
