title: Seed selections for crystallization of calcium phosphate for phosphorus recovery.
abstract: Seed induces and promotes the crystallization of calcium phosphate, and acts as carrier of the recovered phosphorus (P). In order to select suitable seed for P recovery from wastewater, three seeds including Apatite (AP), Juraperle (JP) and phosphate-modified Juraperle (M-JP) were tested and compared. Batch and fixed-bed column experiments of seeded crystallization of calcium phosphate were undertaken by using synthetic wastewater with 10 mgP/L. It showed that AP had bad enduring property in the crystallization process, while JP had better performance for multiple uses, and M-JP was a hopeful seed for P recovery by crystallization of calcium phosphate.
