Model SGW - Grit Washer Brochure

These machines are used for the separation and cleaning of sandy material from wastewater. These machines consist of a conical settling hopper, provided with a stirrer that gives to water a rotational movement; this rotation facilitates the settling process and, at the same time, keeps in suspension the organic matters. The hopper`s bottom is fed with clean water that creates a counter-flow that removes the organic material which is then evacuated from a pipe placed at the upper side of the hopper. The washed sands are removed from the bottom of the hopper by a shafted screw conveyor, while the output cleaned water outflows from a pipe placed at the top of the hopper.
