Calcium phosphate flocculation
WebPhosphate precipitation. Chemical precipitation is used to remove the inorganic forms of phosphate by the addition of a coagulant and a mixing of wastewater and coagulant. The multivalent metal ions most commonly used are calcium, aluminium and iron. Calcium: it is usually added in the form of lime Ca(OH) 2. It reacts with the natural ... Web2.2.3. Flocculation tests The flocculation tests were conducted using a jar test [37] on the algal suspension and three flocculants (i.e. hydroxyapatite (Ca 5(PO 4) 3OH), octacalcium phosphate (Ca 4H(PO 4) 3) and calcium phosphate (Ca 3(PO 4) 2)). The methodology as described by Vandamme et al. [37] was used in our study.
