Features

• A liquid pollution control unit based on the SDI (Silt Density Index) method.
• It consists of a laboratory test baby tank BT-700S, a pressure gauge, a 47 mm stainless steel holder KS-47 and an instantaneous flow meter.
• The test solution is filtered by a filter under constant pressure, and the ratio of the initial filtration rate to the filtration rate after a certain period of filtration is expressed as an index. By selecting the filtration pressure, the pore size of the filter, and the filtration time, you can set the control standard according to the properties of the test solution.
