Frequently Asked Questions

What is Silt Density Index (SDI)?

SDI is a quantitative measure of particulate and colloidal contamination in water that can potentially clog water treatment devices. It is expressed as a percentage and indicates the fouling potential of the water.

What equipment is required to perform the SDI test?

Only two items are needed: a stopwatch and a 500 mL graduated cylinder, available as Hach Product Numbers 2630200 and 108149 respectively.

Why is SDI testing important for water treatment?

SDI testing determines the correct type and placement of pre-filtration systems, preventing premature fouling of expensive filtration and membrane equipment, and ensuring optimal system performance.

Does this test require specialized laboratory skills?

No, the SDI test is a simple procedure that can be performed in the field without specialized training or complex laboratory instrumentation.
