A separator for solid particles from a liquid, such as a dirty industrial machine tool coolant, comprising a settling tank with one or more frames or assemblies of horizontally extending tubular filters and means to removably clamp such frames against a side of the settling tank over suction outlets. Each of the filter frames comprises a chamber into which all of the tubular filters communicate, which chamber is provided with a gasket that is pressed against the vertical wall of the settling tank around an outlet therefrom. Socks may be provided for the tubular filters, which socks may contain seams that are aligned in vertical planes for the easy severance of the cakes of solid particles which build up upon them. A bottom drag out conveyor may be provided for the settling tank and a suction pump draws the liquid through the filters into an adjacent clean tank. When the coating of removed solid particles on the tubular filters becomes excessive, such as after a certain period of time and/or a predetermined vacuum occurs on the intake of the pump, the suction may be automatically shut down, and reverse pressure applied to the filters to bump off the cake that has formed on the filters so it can settle and be removed from the settling tank. If required, a precoat filter medium may be applied to the filters. This precoating filter medium or material may be fed from a hopper onto a screen where jets of liquid disperse it through the screen for introduction into the settling tank above each of the tubular filter frames for direct and rapid deposit on the filters to minimize loss due to settling.
