Investigation of Optimal Mode Parameters of Nanofiltration Separation Process
Downloads
The main operating parameters of the process of nanofiltration separation are investigated in the work: pressure, speed of the circulation flow and height of the pressure chamber of the membrane module to determine their optimal values. Theoretical and experimental studies have shown that relatively small pressure chamber with a height of 0.2–0.4 mm is optimal for ensuring laminar flow of deionized water in the pressure chamber of the membrane device, while the optimal range of transmembrane pressure and tangential flow speed is 5 bar and 5 m/s, respectively, which ensures optimization of the nanofiltration process due to increasing the degree of separation and reducing energy consumption.
