| titleOfInvention | A universal self-cleaning anti-membrane fouling method with pulsed water pressure response |
| abstract | The invention discloses a universal and autonomous anti-membrane fouling method with pulse water pressure response. During the membrane separation process, the piezoelectric filter membrane is stimulated to generate electric charges by periodically changing the transmembrane pressure difference, so as to realize the membrane separation process and the anti-membrane effect. Coupling of membrane fouling processes. The technical scheme of the present invention integrates the prevention and control of membrane pollution, does not use other power supply equipment (especially different from the existing in-situ vibration anti-membrane pollution of piezoelectric filter membrane materials through external voltage stimulation), does not use water treatment chemicals and backwashing The conventional anti-membrane fouling method only relies on the periodically changing transmembrane pressure difference in the process of wastewater membrane separation to stimulate the piezoelectric filter membrane material to generate charges, and through the multiple actions of in-situ generated oxidative radicals, electrostatic repulsion and dielectrophoresis force, it can be Prevent multiple membrane fouling. In the periodic pressure-variable operation mode, the membrane fouling is significantly controlled, and the membrane flux is significantly improved compared with the constant-pressure operation mode. |
