Permeability properties of incineration ashes suspension due to ceramic membrane in supersonic flow field were investigated.
The permeation flux of coloidal suspension in supersonic flow field decreased by prompt fouling. In filtration for one day, the flux decreased with increasing time because of the pore narrowing.
The membrane resistance increased with increasing time. However, backwashing to take off plugging by nitorogen gas was found to be effective for the recovery of flux.
The permeation flux of coloidal suspension under supersonic flow field decreased with increasing the concentration of slurry. The permeation flux, however, change very little with the concentration for not less than 4 mass%. The limitations of concentration to be fluidized slurry under this experimental conditions was found to be 3.5 mass%.
