Apparatus for use in settling or separating finely divided solids, i.e., minerals, from a liquid such as water in which they are suspended. A plurality of settling tanks is provided, each of which is flow connected in series at about the mid-level, which receives processed supernatant fluid in stages. The mineral content of the water in each tank tends to settle by gravity toward the bottom of each tank and is extracted from each tank by extractor pumps. The initial high mineral water is pumped into the first stage tank and is pre-treated by an electromagnet unit surrounding a pipe which contains a helical screw impeller, and each of the succeeding tanks is provided with a pump at about the mid-level and is similarly pre-treated by a similar electromagnetic field and screw impeller in the flow line. Thus, the separation of water containing a high mineral content is affected by gravity and an induced magnetic field impressed by the windings of an electromagnet suspends the particles, and the screw impeller provides a sweeping action to the particles, such that initially processed muddy water is treated in stages to obtain clean water for industrial or home use.
