SDI Tester

Feature: The Silt Density Index (SDI) is calculated upon the sample waters actual decay in flow rate, when it flow trough the 0.45micron pore size filter membrane under 0.207MPA in a certain time. SDI is one of the effective measurements to quantify the amount of the particle and colloid in the pre-treated water. It is an important index ensuring the efficient operation of the reverse osmosis separation process etc. Water Silt Density Index Tester possesses the properties of the convenient membrane installment, speedy pressure adjustment and small testing error etc. The main components of the test apparatus include: inlet connection, Valve, pressure regulator, pressure gauge, A-type adaptor, filter and other connection fittings.
