Abstract
Abstract An apparatus wherein purified water is discharged after separation of particle solid substances from the liquid at its upper part; while particle solid substance is discharged from the bottom of the device after being made to settle downwardly. More particularly, it relates to a compact settler which increases not only the efficiency of solid-liquid separation equipment but also the efficiency of settlement and of concentration equipment.
