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,.

Water/Wastewater Aluminum, can be successfully, removed, from slightly acidic water-based streams with a strong, acid cation, exchanger like AmberSep™ G26 H Resin. If the aqueous stream has a pH from 3 to 6, a weak, acid cation resin, such as AmberLite™ IRC83 H Resin should be considered due to the higher, ion, exchange capacity and economical regeneration.
