Abstract:
An ultrasonic method for in-line control to the pollution of membrane features that in the condition of particular ultrasonic frequency and energy density, an 'Order increment method of ultrasonic working time' is used to optimize the ultrasonic working time and the cross flow speed on the membrane surface in order to minimize to total systematic energy consumption, and under the predefined cross flow speed, the ultrasonic working time is optimized to make the membrane resistant constant.
