through a small diameter (47 mm), 0.45-micron absolute membrane filter while maintaining a pressure of 30 psi. The time required to pass 500 mls at the end of 5, 10, and 15 mins is taken and used to calculate the unit-less SDI value. The silt density index is calculated as follows:...
Figure 1: the Silt Density Index (SDI) Equipment: The feed water has to be supplied with a pressure of 2 bars, which will be regulated with the pressure regulator and reading off the value on the pressure gauge. With the ball valve you turn the flow on and off. ...
Silt Density Index (SDI) is an empirical test developed for measuring the rate of fouling of nano filtration (NF) or RO membranes. Suspended solids and colloidal materials in feed water are one of the biggest problems in reverse osmosis systems. Although most systems have some pre-treatment, ...
