Silt density index is essential, for this reason Everblue offers two types of SDI kits (testers), manual and automatic/electronic. The most frequent obstructions of the RO and nanofiltration membranes is caused by colloidal substances (aluminosilicates - clay). These materials often deposit together with iron corrosion products, precipitated iron hydroxide and biofilms. The SDI test is used to predict and thus prevent fouling of the membrane surface.
