  • Electromagnetic-force-based dewatering for sewage sludge reduction
    Patent number: 10494285
    Abstract: For sewage sludge reduction, an apparatus includes a front-end auxiliary filter plate, a back-end auxiliary filter plate, and a plurality of filter plate modules disposed between the front-end auxiliary filter plate and the back-end auxiliary filter plate. Each filter plate module includes a middle main filter plate, a middle auxiliary filter plate, and a plurality of electromagnetic modules comprising an electromagnetic coil wound around an electromagnetic core. The middle main filter plate and the middle auxiliary filter plate are disposed at opposite sides of the electromagnetic modules. An electric current is applied to the electromagnetic coil, attracting the middle auxiliary filter plates and the main filter plates and applying pressure to the sewage sludge.
