In this paper, through ,wastewater, acidification and c.d. altering, we clarified the pptn. process and electrochem. interaction of phosphate and coexisting ions. The removal of P is attributed to amorphous calcium phosphate (ACP) formation, whereas the removal of bicarbonate is mainly due to calcite (CaCO3) formation and ,acid,-base ,neutralization,.

Abstract Pulsed bed treatment ,of acid, mine drainage (AMD) uses CO2 to accelerate limestone dissolution and intermittent fluidization to abrade and carry away metal hydrolysis products. Tests conducted with a prototype of 60L/min capacity showed effective removal of H+ acidity over the range 196–584mg/L (CaCO3) while concurrently generating surplus ,acid neutralization, capacity.
