SILT DENSITY INDEX (SDI) Membrane fouling is the main cause of permeate flux decline and loss of product quality in reverse osmosis (RO) Systems, so fouling control dominates RO system design and operation. SDI is a measurement of the fouling potential of suspended solids. It measures the time required to filter a fixed volume of water through a standard 0.45µm pore size microfiltration membrane with a constant given pressure of 30 psi (2,07 bar). An SDI of less than 5 is considered acceptable for the reverse osmosis systems and no pre-filtration is necessary. A media (sand-type) filter is required if the value of SDI ranges from 5-10. If the SDI is greater than 10, a 2-stage media filtration is necessary, possibly with the aid of coagulants or settling tanks. .
