SDI test kits: what are they and how do they work?

What is SDI? Silt Density Index (SDI) is a measure to assess the fouling in water purification systems from Suspended solids and colloidal materials. When it comes to reverse osmosis membranes, suspended solids within the water can cause problems. Then these levels get high, it can cause fouling of the membrane. This will lead to: Increased cost for maintenance Reduced lifetime In...

What filter paper is used to measure silt density index (SDI)?

Silt Density Index (SDI)  is a test used to determine the levels of colloidal and particulate suspended solids in the feedwater to reverse osmosis (RO) systems. This in turn will enable you to estimate the fouling potential. This measurement is of importance as it can be used to predict the lifetime of the RO membrane. This can help save time and money. It is measured following the test...
