... is reversed across the membrane once during each backwash cycle, two consecutive backwashing pulses during each cycle is an optimized operation. A chemical cleaning may be required to restore the initial performance of the membrane when the fouling occurs. As for Binxian reservoir water, 0.1% citri ...

... the operating lifetime of the membranes. In this research work, the structural changes that take place in ceramic membranes as a consequence of chemical cleaning were evaluated. As a case study, milk ultrafiltration process was selected since this is a typical and well-established application i ...

... line (OTPL). The optimized cleaning condition was CSDBS = 0.30 wt.%, TMP = 0.10 MPa, CFV = 3 m/s, T = 60 °C, and OTPL = 80 min. The dynamic and chemical interaction between chemical agents, foulants and the membrane was also studied in this research. The methods were successfully applied to th ...
