Abstract
PURPOSE: To completely remove phosphates from an aqueous phosphate-contng. solution, by using a calcined material prepared by calcining fossil coral, which does not contain salt at a fixed temperature.
CONSTITUTION: After salt is removed from fossil coral by washing it with water, the fossile coral is calcined at a 300W500°C. After cooled, the calcined fossil coral is crushed into a proper size, and packed into a packed column or charged into a vessel provided with an agitator. Phosphate-contng. waste water is let flow through the column or vessel. Consequently, phosphates in the filthy water are adsorbed by the calcined fossil coral, and completely removed from the waste water.
