SDI Test Kit

Silt Density Index (SDI) is a measurement used to quantify the amount of particulate contamination in a water sample.

Silt Density Index testing is a widely accepted method for estimating the rate at which colloidal and particle fouling will occur in water purification systems, especially applications using reverse osmosis (RO) membrane elements. The SDI test is commonly used to help ensure that feed water suspended solids do not end up fouling RO systems by plugging the micropores in RO membrane elements.

The PCKem SDI test kit, complete set is used to indicate the quantity of particulate contamination in relatively low-turbidity water supplies for RO membrane. Based on ASTM Method 4189-95, the test is accepted industry-wide to estimate the rate at which colloidal and particle fouling will occur in water purification systems.
