The shortcoming of traditional filter media, such as high and fluctuating resistance, low efficiency for very small size dust, high frequency of regeneration etc.
The thesis designs a frequency-power automatical control unit based on PLC, enabling generators to run reliably even if in the event of heavy load fluctuating.

The result indicates that the theoretical analysis is correct, and no resonance will appear between the fluctuating pressure of water flow and the gate vibration frequency.
