摘要： In a filtration equipment with a filtrate recovery process, in order to achieve reduction in recovery time of suspension in a tank and allow sludge such as filtration aid to be exfoliated readily from filtration elements and discharged, pressurized water is introduced into the tank which includes tubular filtration elements and a plate element provided at upper and lower locations thereof to recover the suspension as filtrate, and pressurized gas such as air or carbon dioxide is introduced into the tank from the suspension side so that water remaining on the suspension side is discharged from the tank by the pressurized gas, whereafter sludge is exfoliated from the filtration elements and then discharged to the outside of the tank.
