Abstract
he method of this invention is effective for removal of colloidal and other suspended particles, and the reduction of boron from lightly polluted water such as grey water (soap solution), underground water in built up area, and any other lightly polluted waters, after flocculation, sedimentation and filtration. In general, this method includes the introduction into the lightly polluted water, such as grey water, of a complex chemical solution which is produced from the natural oxidation of iron pyrites and its surroundings rock formations. With the introduction of this complex chemical solution several chemical bondings are formed, flocculation and sedimentation of suspended particles (coloidal and other suspended particles) and boron. Following this the lightly polluted water such as grey water is passed through the upflow and downflow filters, so that the remaining suspended particles are removed; each filter bed consists of a bar (solid piece) of flexible polyurethane foam, up to 10 cm in depth.
