%X Collect the effluent of Jinhai lake after precision filtration ultrafiltration pretreatment, and use SDI tester (Hangzhou Hengshui filtration Co., Ltd.) to measure the SDI value of water samples. The collection time is from July 5, 2020 to November 2, 2020.  It is obtained according to the standard test method for silent density index (SDI) of Water ASTM d4189-07 (r2014). The measurement is accurate to two decimal places. The value of SDI of produced water after pretreatment is less than 3, which can meet the requirements of nanofiltration / reverse osmosis membrane module for inlet water SDI < 5, and meet the assessment index of the assignment.
