Abstract
A method for controlling a hollow fiber nanofiltration membrane system with controllable power consumption, including the following steps. A filtration flow rate is determined by the program control system according to preset working conditions and the electricity price and the inlet water temperature obtained by a first monitoring module when the hollow fiber nanofiltration membrane assembly is started to perform a filtration process. The inlet water pressure change and the permeability change are monitored and recorded by a second monitoring module during the filtration process. A flushing mode and a flushing intensity of the cleaning system are determined by the program control system according to the inlet water pressure change and the permeability change during the filtration when the filtration process is completed.
