For the most part liquid clarifiers, i.e. apparatuses for removing suspended solids from liquids are unduly complicated in terms of structure and/or operation. A simple clarifier includes an elongated cylindrical tank with a frusto-conical bottom end, a large diameter, central downflow tube extending downwardly from the closed top end of the tank to beyond the middle of the tank for receiving a solids-containing liquid from a smaller diameter inlet tube, and for discharging the liquid against a conical deflector. Solids settle to the bottom end of the tank for removal via an outlet pipe or for recycling via a return pipe and pump to the inlet pipe. Liquid rising in the tank overflows an annular weir or is decanted and is discharged through a second outlet pipe.
