Research on SDI Fast Test Method
Hongwei Li · Machine Tool & Hydraulics · 2007
Silt density index(SDI)is a most important index of evaluating water pretreatment effect of RO system.Some existing SDI test means using manual measurement are time-consuming,and the artificial error could be resulted.According to actual needs of corporation and the development of SDI test technology,a new SDI test method was developed by using AVR microcontroller and SITRANS FM Intermag as hard core,and a new measure system was established.The system can measure SDI with high efficiency and veracity.
