Portable Silt Density Index (SDI) Test Kit – AQSDIKIT

Note: This kit already includes with 25 pieces of membrane papersIn order to measure the degree of this fouling problem, a concept called Silt Density Index or SDI is used. Here filtration rates are calculated by exposing a 0.45-micron filter to the feed water under pressure and filtration rates are calculated. With this SDI test kit, you can get a clear measure of the degree of suspended solids and colloidal materials you have in your feed water. In most cases, an SDI of less than 5 is considered acceptable for the reverse osmosis systems. Determiningthe SDI value, would be instrumental in investigating relevant water purified technology or device which underASTM method 4189-95 is generally accepted.
